I ka honua o ka hana ʻana a me ka ʻenekinia mīkini, ʻo ka hana ʻana i nā mea kūpono ke kī. Ma laila e komo ai nā pae pae. Ua like lākou me nā lula no ke ʻano o ka hoʻohālikelike ʻana o nā spirals ma ka bolt me nā spirals i loko o kahi nut. He mea koʻikoʻi kēia mau lula no ka mea ʻike lākou i ka paʻa pono ʻana o nā ʻāpana, a hiki iā lākou ke mālama i ka hana a lākou i manaʻo ai e hana me ka haki ʻole.
E hoʻomaka kākou ma ka hoʻomaopopo ʻana i ke ʻano o nā pae pae . ʻO ka waiho wale ʻana, he mau alakaʻi ia e wehewehe i ke ʻano, ka nui, a me ka hoʻomanawanui o nā kaula i hoʻohana ʻia i nā bolts, screws, a me nā nati. E noʻonoʻo iā lākou e like me kahi puke meaʻai no ka hana ʻana i nā milo i kūpono pū. ʻO kēia mau kūlana e hōʻoiaʻiʻo i kahi bolt mai kahi hui e komo i loko o kahi nut mai kahi ʻē aʻe, e mālama ana i ka kūlike a me ka pololei ma waena o nā ʻoihana like ʻole.
He kuleana koʻikoʻi ka pae pae thread i ka honua o ka hana ʻenehana a me ka ʻenekinia . ʻO lākou nā koa kaulana ʻole i ka hui ʻana o nā mea āpau mai nā ʻāpana uila ma ka papa kaapuni a hiki i nā kino nui o nā mokulele. I nā ʻoihana e like me hana mokulele , nā mea a me nā mokulele mokulele , hōʻoia kēia mau maʻamau i kēlā me kēia mea paʻa paʻa , a me nā wili , a me nā ʻāpana mechanical e hui pū me ka pololei a me ka ikaika . He mea koʻikoʻi kēia no ka hoʻokumu ʻana i kahi pilina paʻa akā no ka mālama ʻana i ke kūpaʻa a me ka palekana o nā huahana.
I kēia manawa, e hele wikiwiki kākou ma ke ala mōʻaukala. ka Unified Thread Standard (UTS) ma ke ʻano he ala e hoʻomaʻamaʻa a hoʻopaʻa ʻia i Ua hoʻokomo ʻia nā kaula screw ma United States a me Kanada. Ma mua o ka UTS, ua nui nā pae maʻamau, he mea huikau loa. Ua lawe mai ʻo UTS i nā mea a pau ma ka ʻaoʻao like me ʻelua mau ʻano nui: Unified National Coarse (UNC) a me Unified National Fine (UNF).
l UNC Threads : ʻIke ʻia no ko lākou pitch koʻikoʻi , maikaʻi kēia mau lola no nā noi maʻamau. ʻOi aku ka maʻalahi o ka hana ʻana a me ka lawelawe ʻana, e hana ana iā lākou i koho kaulana i nā ʻoihana e pono ai nā hoʻonā hoʻopaʻa ʻana i hiki ke ʻae i ke kaumaha haʻalulu a me ka wikiwiki o ka huli ʻana..
l UNF Threads : Loaʻa iā lākou kahi pitch maikaʻi , hāʻawi i ka ikaika kiʻekiʻe a me ka pololei . Hoʻohana pinepine ʻia lākou i nā noi e like me ka aerospace a me nā mea kani pololei , kahi e helu ai kēlā me kēia millimeter.
Hāʻule nā ʻāpana UNC a me UNF ma lalo o ka Unified Screw Thread Series , e like me ka ʻohana nui o nā kaula wili i hoʻolālā ʻia e hana like.
No ka noʻonoʻo ʻana, e noʻonoʻo i kahi pakuhi Screw Thread . Hoʻopaʻa ʻia kēia pakuhi i nā nui a me nā ʻano lola ma lalo o ka UTS, e komo pū ana me nā loina Unified coarse pitch a me Unified fine pitch threads . He mea hoʻohana ia no nā ʻenekinia a me nā mea hana hana e hana i ke koho pono no kā lākou mau noi kikoʻī.
Ma nā ʻōlelo kūpono, aia nā pae pae ma hope o nā hiʻohiʻona ma kahi kokoke i kēlā me kēia huahana mechanical. No ka laʻana, i nā lako uila , ʻo ka pololei o nā kaula UNF e hōʻoia i ka alignment pololei o nā ʻāpana. Ma nā noi ʻoi aku ka nui, e like me nā kaʻa a i ʻole nā mokulele , kōkua nā kaula UNC i ke kūkulu ʻana i ikaika nā ʻāpana chassis a me nā ʻāpana ʻenekini..
He mea koʻikoʻi ka hoʻomaopopo ʻana i nā pae pae, ʻoi aku ka ʻokoʻa ma waena o UNF a me UNC . ʻAʻole ia e pili ana i ka hoʻopili ʻana i ʻelua ʻāpana; e pili ana i ka hōʻoia ʻana i palekana , ka hilinaʻi , a me ka pono . Inā he hana kiʻekiʻe ma ka aerospace a i ʻole he hui nui i ka ʻenekinia mechanical , ʻo ke ʻano o ka pae kūpono - inā ʻo UNF a i ʻole UNC - hiki ke hoʻololi i ka hana a me ka lōʻihi o ka huahana. I ka hōʻuluʻulu ʻana, ʻo nā pae pae e like me UNF a me UNC ma lalo o ka Unified Thread Standard he mea nui i ka hana ʻana i nā huahana i hilinaʻi a palekana. Hoʻopaʻa lākou i nā mea āpau mai ka liʻiliʻi liʻiliʻi i ka papa kaapuni a hiki i ka bolt nui loa i loko o kahi mokulele e pili ana i ka hana, e hāʻawi ana i ka ikaika e pono ai , pololei , a me ke kūpaʻa e pono ai i nā noi like ʻole.
Ua like ka Unified Thread Standard (UTS) me ka rulebook no nā lola i hoʻohana ʻia ma ʻAmelika ʻĀkau. ʻO ia ka mea e hoʻopaʻa pono ai ka wili mai kekahi wahi i loko o kahi hua mai kahi ʻē aʻe. He mea koʻikoʻi kēia maʻamau i nā ʻoihana e like me ka aerospace , automotive manufacturing , a me nā lako uila.
ʻEkolu mau māhele nui o ka UTS:
1. Puka Uila : ʻO kēia ke ʻano o ka milo. E noʻonoʻo ʻoe e like me ke ʻano o ka bolt a i ʻole ka wili. He mea koʻikoʻi ia no ka mea e hoʻoholo i ka maikaʻi o ka hui ʻana o ʻelua ʻāpana.
2. Series : E pili ana kēia i nā ʻano milo like ʻole. Ma UTS, ʻelua pūʻulu nui - Unified National Coarse (UNC) a me Unified National Fine (UNF). ʻOi aku ka liʻiliʻi o ka moʻo koʻikoʻi (UNC) i kēlā me kēia ʻīniha, a ʻoi aku ka nui o ka moʻo maikaʻi (UNF). Pili kēia ʻokoʻa i ka ikaika a me ka paʻa o ka pilina.
3. Nā Papa Pono : Ua like kēia me ke kiʻekiʻe o ka snugness ma waena o nā kaula. E pili ana ia i ka paʻa a ʻoluʻolu paha. Nui nā papa, kūpono kēlā me kēia no nā noi like ʻole.
Ma ʻAmelika ʻĀkau, aia ka UTS ma nā wahi a pau. Penei kona hoʻohana ʻana:
l Mea Hana Hana : Hoʻohana nā ʻoihana i ka UTS no ka hana ʻana i nā ʻano mea āpau. Mai nā papa kaapuni liʻiliʻi a hiki i nui nā ʻāpana mīkini mokulele .
l Nā Mea Hana Pono : Ma nā hāmeʻa a me nā mea pono e pono ai ka pololei kiʻekiʻe loa , e like me ka aerospace a i ʻole nā mea hana mokulele , kōkua ʻo UTS i ka hana ʻana i nā ʻāpana kūpono.
l Nā ʻenehana kaʻa a me nā mīkini : Pono nā kaʻa, nā kaʻa, a me nā mīkini i nā hale hana i nā ʻāpana kūpono. Hana kēia i ka UTS, inā paha no nā ʻāpana ʻenekini , chassis , a i ʻole nā hale kino.
l Nā ʻĀpana Electronic : Ma nā hāmeʻa liʻiliʻi, he kuleana nui ka UTS. Hoʻopaʻa ʻo ia i nā bolts liʻiliʻi a me nā wili i loko o nā mea uila e pili pono.
E noʻonoʻo ʻoe ke kūkulu nei ʻoe i robot. Pono ʻoe i nā bolts a me nā screws e hoʻopaʻa paʻa iā ia. E koho ʻoe i ka pae UNC a i ʻole UNF pono e pili ana i ka hana a ka robot. Pono anei ia e pale i ka nui o ke kaumaha puiwa ? A i ʻole pono e pololei maoli? Alakaʻi ʻo UTS iā ʻoe i kēia mau koho.
Ua like ka UTS me ka ʻōlelo a nā mea hana a pau ma ʻAmelika ʻĀkau e ʻōlelo ai. E pili ana i ka hōʻoia ʻana e pili pono nā mea a pau, inā paha he wili liʻiliʻi i loko o ke kelepona a i ʻole ka pahu nui i ka mokulele. Mālama kēia maʻamau i nā mea palekana, ikaika, a me ka hana maʻalahi.
E luʻu kākou i loko o UNF Threads , kaulana no kā lākou Unified Fine Pitch . ʻO kēia mau milo nā mea kiʻi kikoʻī o ka honua thread. ʻOi aku ka nui o nā milo i kēlā me kēia ʻīniha ma mua o nā milo UNC , ʻo ia hoʻi, ʻoi aku ka maikaʻi o lākou a kokoke loa. ʻAʻole kēia hoʻolālā maikaʻi no ka hōʻike wale ʻana; e pili ana i ka pololei.
ʻO nā pae UNF ke koho i nā hiʻohiʻona kahi kiʻekiʻe ka pololei a me ka ikaika . Eia ko lākou ʻālohilohi:
l Aerospace : Ma nā mokulele a me nā mokulele, pono kēlā me kēia wahi liʻiliʻi. Hoʻohana ʻia nā pae UNF ma ʻaneʻi no ko lākou pololei.
l Mea Pono Pono : E noʻonoʻo i nā mea hana i loko o nā labs a i ʻole nā mea hana lapaʻau. Kōkua nā pae UNF i kēia mau hāmeʻa i pololei a hilinaʻi.
l Hana 'Oihana : I loko o nā kaʻa, ʻoi aku hoʻi i nā ʻāpana ʻenekini a me nā ʻāpana uila , hāʻawi nā kaula UNF i ka pono kūpono.
l Nā lako uila : ʻOiai ma nā papa kaapuni liʻiliʻi , he mea nui nā kaula UNF no ka hoʻopaʻa ʻana i nā mea āpau.
Ke kamaʻilio mākou e pili ana i nā ana o nā pae UNF, ke nānā nei mākou i kahi Screw Thread Chart . Hōʻike kēia pakuhi i nā nui āpau - ke anawaena, ka pitch, a me ka lōʻihi. Hiki ke ʻokoʻa ke anawaena o nā kaula UNF mai ka liʻiliʻi a hiki i ka nui, akā ʻo ke kī ʻo ka pitch maikaʻi - ʻoi aku nā kaula i kēlā me kēia ʻīniha o ka wili.
I ka honua o ka hana kiʻekiʻe, ua like nā pae UNF me nā VIP. Hāʻawi lākou:
l Ka ikaika kiʻekiʻe : Ma muli o ko lākou pitch maikaʻi, hiki iā lākou ke mālama i ka ukana a me ke kaumaha.
l Hoʻohui paʻa : ʻoi aku ka nui o nā kaula i ʻoi aku ka paʻa. He mea koʻikoʻi kēia i nā ʻāpana ʻaʻole pono e wehe, ʻoi aku ma lalo o ka haʻalulu.
l Ka pololei : Me ka nui o nā kaula, ʻaʻole hiki ke neʻe a i ʻole ke kuhi hewa. He mea nui kēia i nā mea hana pololei a me nā lako aerospace.
E noʻonoʻo ʻoe e hui nei i kahi drone ʻenehana kiʻekiʻe. Pono pono kēlā me kēia ʻāpana i kūpono. Hiki i nā loina UNF ke kōkua iā ʻoe e wili i kēlā me kēia ʻāpana me ka pololei, e hōʻoia i ka paʻa a hilinaʻi ka drone.

I ka hōʻuluʻulu ʻana, pili nā kikoʻī a me ka pololei o nā pae UNF. ʻO lākou nā poʻe koa ʻike ʻole i ka nui o nā ʻenehana kiʻekiʻe a me nā noi kiʻekiʻe, mai ka hohonu o ka lewa ma kahi mokulele a hiki i nā mea koʻikoʻi o ka mīkini kaʻa hana kiʻekiʻe. ʻO kā lākou pitch maikaʻi a me ka ikaika kiʻekiʻe e pono ai lākou i ka honua o ka hui pololei a me ka hana kiʻekiʻe.
nā loina UNC no nā loina Kū Unified National Coarse . E noʻonoʻo iā lākou he ʻano ikaika a hilinaʻi i ka ʻohana thread. He liʻiliʻi ko lākou mau milo i kēlā me kēia ʻīniha ke hoʻohālikelike ʻia me nā loina UNF , ʻo ia hoʻi, ʻoi aku ka ʻoi aku o lākou. ʻAʻole kēia ʻano koʻikoʻi he drawback; ʻoiaʻiʻo he mea hoʻohui nui i nā kūlana he nui.
Ma hea e kūpono ai nā pae UNC? Eia kahi nānā wikiwiki:
l Hana : Ma nā hale a me nā alahaka, kūpono nā kaula UNC no ka hoʻopaʻa ʻana i nā mea kaumaha.
l Mīkini Nui : I nā mīkini ʻaʻole pono i ka precision maikaʻi loa, e like me kekahi mau wahi o ke kaʻa a i ʻole nā mea hana nui, hana maikaʻi nā kaula UNC i ka hana.
l Nā mea kūʻai aku : ʻO nā mea a mākou e hoʻohana ai i kēlā me kēia lā, e like me nā lako a i ʻole nā mea hana hale, loaʻa pinepine nā kaula UNC e mālama pū ana.
ʻIke ʻia nā pae UNC no nā mea ʻelua: ka ikaika a me ka hoʻomanawanui.
l Ka ikaika : Ua lawa ko lakou ikaika no ka paa ana i na hale nunui, nolaila oe e ike ai ia lakou i ke kukulu ana a me ka mīkini kaumaha.
l Hoʻomanawanui : Ua ʻoi aku ko lākou kala ʻana ma mua o nā kaula maikaʻi. ʻO ia ke ʻano hiki iā lākou ke mālama i ka lepo, ka pōʻino, a ʻoi aku ka maʻalahi o ka wili a wehe ʻana, ʻoi aku ka maikaʻi ma nā wahi ʻino.
I ka hana ʻana i nā mea me nā pae UNC, aia kekahi mau mea e hoʻomaopopo ai:
l Maʻalahi o ka hana ʻana : ʻoi aku ka maʻalahi a me ka wikiwiki o ka hana ʻana ma mua o nā milo maikaʻi. He mea nui kēia i ka wā e hana ana ʻoe i nā kaukani wili a i ʻole bolts.
l Kūʻai-Effective : No ka mea maʻalahi lākou e hana, pinepine lākou i ka liʻiliʻi. He mea koʻikoʻi kēia i nā huahana kahi āu e makemake ai i nā mea hoʻopaʻa he nui akā ʻaʻole pono i ka precision super fine.
l Versatility : He mea maʻalahi lākou. Hiki iā ʻoe ke hoʻohana i nā kaula UNC i nā ʻano huahana like ʻole, mai nā mīkini hana kaumaha a i nā mea o kēlā me kēia lā.

4. E nānā i ka pakuhi : Hiki iā ʻoe ke kuhikuhi i kahi Screw Thread Chart no ka hoʻohālikelike wikiwiki. Hōʻike kēia pakuhi i nā kaula UNF a me UNC me ko lākou pitch a me ke anawaena.
He mea koʻikoʻi ka loaʻa ʻana o nā ana kūpono. Eia kekahi mau ʻōlelo aʻoaʻo:
l E hoʻomaʻemaʻe i nā kaula : Ma mua o ke ana ʻana, e hoʻomaʻemaʻe i nā kaula. Hiki i ka lepo ke hoʻopilikia i kāu mau ana.
l Ana i kekahi mau Manawa : I mea e pale aku ai i na hewa, e ana i na manawa elua a e lawe i ka awelika.
l E hoʻohana i nā mea hana maikaʻi maikaʻi : E hoʻokomo i nā calipers a me nā ana kiʻekiʻe no nā ana pololei.
l Noho Paʻa : I ke ana ʻana, e hoʻopaʻa paʻa i kāu mau mea hana e pale aku ai i ka paheʻe ʻana a me ka loaʻa ʻana o nā heluhelu hewa.
Ke hana nei ʻoe i kahi papahana, ʻo ka ʻike inā hoʻohana ʻoe i nā pae UNF a i ʻole UNC hiki ke hana a uhaʻi paha i kāu hana. ʻO ke ana ʻana a me ka ʻike pono ʻana i kēia mau lola e hōʻoia i ka kūpono o kāu mau mea hoʻopaʻa , inā paha ʻoe e kūkulu ana i kahi ʻāpana, hoʻoponopono kaʻa, a i ʻole e hui pū ana i nā ʻāpana aerospace. ʻO nā ana maikaʻi e alakaʻi i nā pilina ikaika, paʻa, a palekana i nā mea āu e hana ai a hoʻoponopono paha.
ʻO nā pae UNF (Unified National Fine) e like me ka poʻe loea pololei i ka honua thread. Eia kahi i kū maoli ai lākou:
l Aerospace a me Aviation : Ma nā mokulele a me nā mokulele, pono e hemolele kēlā me kēia wahi liʻiliʻi. Hoʻohana ʻia nā kaula UNF i nā ʻāpana ʻenekini a me nā hale kino no ko lākou pololei kiʻekiʻe.
l Ka Hana Hana : Ma nā kaʻa, ʻoi aku hoʻi i nā ʻāpana ʻoi aku ka maʻalahi e like me nā ʻāpana uila , hāʻawi nā kaula UNF i ka pono kūpono.
l Nā lako uila : No nā hāmeʻa a me nā mea hana, kahi e helu ai kēlā me kēia millimeter, pono nā pae UNF no ka pololei a me ka pili paʻa..
I ka hana ʻana i nā mea hoʻopaʻa he nui me ka wikiwiki a me ka maikaʻi, UNC (Unified National Coarse) thread ka mea e hele ai:
l Hana 'ia : I loko o nā hale a me nā mea hana, ho'ohana 'ia nā kaula UNC i nā bolts a me nā wili no ko lākou ikaika a me ka ma'alahi o ka ho'ohana.
l Mīkini Nui : No nā mīkini e pono ai nā mea hoʻopaʻa paʻa a hilinaʻi, hāʻawi nā kaula UNC i ke kaulike kūpono o ka ikaika a me ka maʻalahi o ka lawelawe ʻana.
Loaʻa i kēlā me kēia ʻano o ke kaula kona mana mana no nā ʻoihana like ʻole:
l UNF Threads : I nā mea hana pololei a me ka aerospace , kahi e koʻikoʻi ai nā kikoʻī āpau, pono nā kaula UNF no ko lākou ikaika kiʻekiʻe a me ka pololei..
l UNC Threads : Ma nā ʻoihana e like me ke kūkulu ʻana a me nā mīkini kaumaha, kahi e pono ai nā mea hoʻopaʻa paʻa a paʻa pono, ʻo nā kaula UNC nā mea punahele.
ʻAʻole maʻalahi ka hana ʻana me nā kaula. Eia kekahi mau pilikia:
l Pono i ka Mīkini : ʻO ka hana ʻana i nā kaula UNF e koi i ka pololei kiʻekiʻe ma ka mīkini CNC . Hiki i kahi hewa liʻiliʻi ke hoʻololi nui.
l Ka lawelawe ʻana a me ka hui ʻana : ʻoi aku ka maʻalahi o nā kaula UNC, ʻoi aku ka maʻalahi, akā pono e hana pono ʻia i mea e kūpono ai i nā noi ʻoi aku ka maikaʻi.
l Koho Material : He mea koʻikoʻi ke koho ʻana i nā mea no nā pae UNF a me UNC. Hoʻopilikia ia i ke ikaika o ke kaula , kūpaʻa , a me ke kū'ē i ke kaumaha.
Inā ʻo ia ka pono o ka noi ʻana o nā kaula UNF i ka aerospace a me nā ʻāpana uila a i ʻole ka paʻa o nā kaula UNC i ke kūkulu ʻana a me nā mīkini, hana ʻelua i nā kuleana koʻikoʻi i kā lākou mau kahua. ʻO ka hoʻomaopopo ʻana i kā lākou hoʻohana kikoʻī a me nā pilikia e kōkua i ka hana ʻana i ke koho thread kūpono no kēlā me kēia noi kūʻokoʻa, e hōʻoia i ka pono a me ka palekana o ka huahana hope.
ʻO ke koho ʻana i ke ʻano thread kūpono - UNC a i ʻole UNF - he mea koʻikoʻi. Eia ka mea e noʻonoʻo ai:
1. Pono e noi : Ke hana nei ʻoe i kahi mea e pono ai ka pololei kiʻekiʻe, e like me kahi ʻāpana mokulele ? E hele no UNF. No ka hana maʻamau, ʻo UNC kāu koho maikaʻi loa.
2. Manaʻo ikaika : Hāʻawi nā kaula UNF i ka ikaika ma muli o ko lākou pitch maikaʻi, e hoʻolilo iā lākou i mea kūpono no nā noi kiʻekiʻe.
3. Kaiapuni Hui : Inā pili ke kaiapuni i ka lepo a i ʻole ka pōʻino, ʻoi aku ka kala ʻana o nā kaula koʻikoʻi o UNC.
4. Nā Hana Hana : Loaʻa iā ʻoe nā mea hana no ka hoʻopaʻa ʻana UNF pono? Inā ʻaʻole, ʻoi aku ka maʻalahi o ka UNC.
Loaʻa i kēlā me kēia ʻoihana kona makemake ponoʻī:
l Aerospace : Hoʻohana mau ʻia ʻo UNF no kāna kikoʻī kiʻekiʻe a me ka ikaika.
l Kūkulu ʻia : ʻOi ʻia ʻo UNC no kona ikaika a me ka maʻalahi o ka hoʻohana.
l Automotive : He hui o nā mea ʻelua, e pili ana i ka ʻāpana i hana ʻia.
ʻO ka loaʻa ʻana o ka hoʻopaʻa ʻana he mea nui:
l E nānā i ka hoʻohālikelike : E hoʻopaʻa mau i ke ʻano o ke kaula o ka bolt e like me ka nut. Pono ka bolt UNF i kahi nut UNF.
l E nānā i ka Palapala Uila Screw : Kōkua kēia pakuhi i ka hoʻohālikelike pono ʻana i nā milo, e hōʻike ana i ka pitch a me ka nui o ka milo..
l E noʻonoʻo i ka mea : Pono ka mea o ka bolt a me ka nut e kūpono no kahi pilina paʻa.
E ʻōlelo paha ʻoe e hui nei ʻoe i kahi ʻāpana uila. E koho paha ʻoe i nā pae UNF no ko lākou pitch maikaʻi a me ka pololei . Ma ka ʻaoʻao ʻē aʻe, inā ʻoe e kūkulu ana i kahi waihona puke, ʻoi aku ka maikaʻi o nā pae UNC no ko lākou ikaika a me ka maʻalahi o ka lawelawe ʻana.
ʻO ke koho ʻana ma waena o UNC a me UNF thread e iho mai i ka hoʻomaopopo ʻana i nā koi kikoʻī o kāu papahana, nā kūlana ʻoihana, a me ka hōʻoia ʻana i ka kūlike o nā mea āpau i pili. Inā paha no nā mea hana maʻalahi a i ʻole nā mea hana paʻa, ʻo ke ʻano milo kūpono e hōʻoia i paʻa , ka ikaika , a me ka kūleʻa holoʻokoʻa o kāu hui.
Ke hoʻopau nei mākou, e hoʻomanaʻo kākou i nā kuleana koʻikoʻi o nā pae UNF a me UNC ma nā ʻoihana like ʻole. ʻO kēia mau kaula, liʻiliʻi e like me ka mea i ʻike ʻia, he mea nui i ka hōʻoia ʻana i ka palekana, pololei, a me ka hana o nā noi he nui.
l UNF Threads : ʻO kā lākou pitch maikaʻi e hoʻolilo iā lākou i mea kūpono no ke kiʻekiʻe kiʻekiʻe a me ka ikaika i koi ʻia e like me aerospace , nā mea hana , a me ka hana kaʻa..
l UNC Threads : ʻIke ʻia no ko lākou pitch koʻikoʻi, pono kēia mau kaula i ke kūkulu ʻana, nā mīkini kaumaha, a me nā huahana o kēlā me kēia lā no ka maʻalahi o ka hoʻohana ʻana a me ka ikaika.
Ke koho ʻana i ka pae kūpono - UNF a i ʻole UNC - iho i lalo i:
l Ka hoʻomaopopo ʻana i ka noi : ʻO nā pono kikoʻī o kāu papahana, inā he kiʻekiʻe a paʻa paha, e alakaʻi i kāu koho.
l Nā Kūlana ʻOihana : ʻO ka ʻike ʻana i nā hui ʻoihana kōkua i ka hana ʻana i kahi koho ʻike.
l Ka hoʻohālikelike : ʻO ka hōʻoia ʻana i ka pili ʻana o nā kaula, nā bolts, a me nā nati āu e koho ai he mea koʻikoʻi ia no ka hui kūleʻa.
He liʻiliʻi paha nā kaula, akā nui ko lākou hopena. Mai ka mokulele e lele ana ma luna o mākou a hiki i nā mea uila a mākou e hoʻohana ai i kēlā me kēia lā, ua paʻa nā kaula UNF a me UNC i ko mākou honua. No laila i ka manawa aʻe e hana ana ʻoe i kahi papahana, e noʻonoʻo i kēia mau koa liʻiliʻi. Hiki i kāu koho ma waena o UNF a me UNC ke hoʻololi i ka ikaika, ka pololei, a me ka lōʻihi o kāu hana ʻana.
Nīnau: He aha ka ʻokoʻa ma waena o nā pae UNF a me UNC?
A: ʻoi aku ka maikaʻi o nā loina UNF; ʻOi aku ka maʻemaʻe o nā kaula UNC. Nui aʻe nā kaula o ka UNF i kēlā me kēia ʻīniha. He mea maʻamau ka UNC i ka hoʻohana maʻamau.
Nīnau: I ka manawa hea e hoʻohana ai au i nā pae UNF ma luna o nā pae UNC?
A: E hoʻohana i ka UNF no ka hoʻoponopono ʻoi aku ka maikaʻi a me ka hoʻoponopono. ʻOi ʻia ka UNF i nā noi e koi ana i ka pololei kiʻekiʻe.
Nīnau: Pehea e ana au i ka pae pae no nā pae UNF a me UNC?
A: E hoʻohana i kahi anana lola no ka helu ʻana i nā milo i kēlā me kēia ʻīniha. E ana i ka mamao peak-to-peak ma waena o nā milo. E hoʻohālikelike me nā kūlana i ʻike ʻia.
Nīnau: Hiki ke hoʻololi ʻia nā pae UNF a me UNC?
A: ʻAʻole, loaʻa iā lākou nā pae ʻokoʻa. Hiki ke hoʻololi i ka pōʻino. E hoʻohālikelike mau i ke ʻano milo pololei.
Nīnau: He aha nā mea hana e pono ai iaʻu e hana me nā pae UNF a me UNC?
A: Pono ʻoe i nā paʻi a me ka make, kahi anana pae, a me nā wrenches. E hōʻoia i nā mea hana e kūlike me ke ʻano o ka pae. Pono paha ka lubrication.
