Di Unified Thread Standard (UTS) tan lɛk di rulbuk fɔ di trɛd dɛn we dɛn kin yuz na Nɔt Amɛrika. Na wetin de mek shɔ se skru we kɔmɔt na wan ples fit insay nat we kɔmɔt na ɔda ples.

UTS gɛt tri men pat dɛn:
1. Thread Form : Dis na di shep fɔ di trɛd. Tink bɔt am lɛk di pɔtn we de na bolt ɔ skru. I rili impɔtant bikɔs na in de disayd aw tu pat dɛn go fit togɛda fayn fayn wan.
2. Series : Dis na bɔt di difrɛn kayn trɛd dɛn. Insay UTS, tu men siriɔs wan dɛn de - Yunaytɛd Nashɔnal Kɔs (UNC) ɛn Yunaytɛd Nashɔnal Fayn (UNF). Di kɔs siriɔs (UNC) gɛt smɔl trɛd dɛn pan wan inch, we di fayn siriɔs (UNF) gɛt mɔ. Dis difrɛns kin afɛkt aw di kɔnekshɔn go strɔng ɛn aw tayt.

Na Nɔt Amɛrika, UTS de ɔlsay. Na dis na aw dɛn de yuz am:
