FAQ a ni.
Q: UNF leh UNC thread te hi eng nge an danglamna?
A: UNF thread te hi a fin zawk a; UNC thread te hi a coarser zawk. UNF hian inch khatah thread a nei tam zawk. UNC hi a tlangpuiin hman a ni zawk.
Q: UNC thread aiin engtikah nge UNF thread ka hman ang?
A: Tension tha zawk leh finer adjustment atan UNF hmang ang che. UNF hi precision sang zawk mamawh application-ah chuan duh zawk a ni.
Q: UNF leh UNC thread te tan thread pitch hi engtin nge ka teh ang?
A: Inch khata thread chhiar nan thread gauge hmang ang che. Thread inkar peak-to-peak distance teh rawh. tehfung hriat tawh nen khaikhin rawh.
Q: UNF leh UNC thread te hi an inthlak danglam thei em?
A: Ni lo, thread pitch hrang hrang an nei. Interchanging hian chhiatna a thlen thei. Thread type dik tak nen inmil fo rawh.
Q: UNF leh UNC thread hmanga hnathawh tur hian eng hmanrua nge ka mamawh?
A: Tap leh dies, thread gauge, leh wrench te i mamawh ang. Tools te chu thread type nen a inmil em tih enfiah rawh. Lubrication pawh a ngai mai thei.
