Pamusoro pehumwe hunhu hwepakutanga, hwakadai sehukobvu hwemusoro nedivi rakatarisana nemusoro, chikamu chakasiyana kwazvo chezviyero zvataurwa zve screws ishinda. Threads dzeGB, DIN, JIS, nezvimwewo dziri muMM (millimeters), pamwe chete dzinonzi metric threads. Threads dzakadai seANSI, ASME, dziri mu inches uye dzinonzi American standard threads. Kunze kwemetric threads neAmerican threads, kunewo BSW-British standard, uye threads dziriwo mu inches, dzinowanzozivikanwa seWhitworth threads.
Tambo yemetric iri muMM (mm), uye kona yayo ye cusp i60 degrees. Tambo dzese dzeAmerican neImperial dzinoyerwa nemainchi. Kona ye cusp yeshinda yeAmerican i60 degrees, nepo kona ye cusp yeshinda yeBritish i55 degrees. Nekuda kwemayuniti akasiyana ekuyera, nzira dzekumiririra tambo dzakasiyana dzakasiyanawo. Semuenzaniso, M16-2X60 inomiririra tambo ye metric. Zvinoreva chaizvo kuti dhayamita ye nominal ye screw i16MM, pitch i2MM, uye kureba i60MM. Mumwe muenzaniso: 1/4-20X3/4 zvinoreva tambo yeBritish system. Zvinoreva chaizvo kuti nominal dhayamita ye screw i1/4 inch (one inch=25.4MM), kune mazino makumi maviri pa inch imwe, uye kureba i3/4 inch. Pamusoro pezvo, kana uchida kuratidza screws dzakagadzirwa neAmerica, UNC neUNF zvinowanzo wedzerwa mushure me screws dzakagadzirwa neBritish kuti zvisiyanise pakati pe coarse threads dzakagadzirwa neAmerica ne fine threads dzakagadzirwa neAmerica.
Yihe enterprise ikambani inonyanya kugadzira masikuruu eAmchine akagadzirwa kuUS ANSI, sikuruu yemuchina yeBS, bolt corrugated, indlcuidng 2BA, 3BA, 4BA; masikuruu emuchina akagadzirwa kuGerman DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967); GB Series nedzimwe mhando dzezvigadzirwa zvakajairwa nezvisiri zvakajairwa zvakaita semasikuruu emuchina nemhando dzese dzemasikuruu emuchina webrass.
