Amabhawodi angama-hexagonalasetshenziselwa ukuhlanganisa izingxenye zensimbi ndawonye.Zivame ukusetshenziswa ekwakheni, imishini kanye nezicelo zezimoto.Ikhanda le-hex le-bolt livumela ukuqina nokukhululeka kalula ngesikrufu noma isokhethi, okwenza kube ukukhetha okudumile kokuvikela izinto ezisindayo.

Ukuze ulinganise i-metric bolt, udinga ukunquma ububanzi, ukuphakama, nobude.

1. Ububanzi: Sebenzisa i-caliper ukukala ububanzi bebhawodi.Isibonelo, uma kuyibhawodi le-M20, ububanzi bungama-20mm.

2. Ukuphakama kochungechunge: Sebenzisa i-pitch gauge ukuze ulinganise ibanga phakathi kwemicu.Lokhu kuzokusiza ukuthi unqume iphimbo lentambo, okubalulekile ukufanisa ibhawudi nenathi elilungile.

3. Ubude: Sebenzisa irula noma isikali setheyiphu ukukala ubude bebhawodi ukusuka phansi kwekhanda kuya ekugcineni.

Ngokulinganisa ngokunembile lezi zici ezintathu, ungakwazi ukuhlonza futhi ukhethe ibholidi ye-metric elungile yohlelo lwakho lokusebenza oluthile.

I-"TPI" imele "imicu iyintshi ngayinye."Kuyisilinganiso esisetshenziselwa ukukhombisa inombolo yezintambo ezikhona kubhawodi eyiyintshi eyodwa noma isikulufu.I-TPI ukucaciswa okubalulekile okufanele kucatshangelwe lapho ufanisa amabhawudi namantongomane noma kunqunywa ukuhambisana kwengxenye enentambo.Isibonelo, ibholidi engu-8 TPI isho ukuthi ibhawodi linemicu egcwele engu-8 iyintshi eyodwa.

Ukuze unqume ukuthi i-bolt iyimethrikhi noma i-imperial, ungalandela le mihlahlandlela evamile:

1. Isistimu yokulinganisa: Hlola izimpawu kumabhawodi.Ama-metric bolt ngokuvamile amakwa ngohlamvu “M” alandelwe inombolo, efana ne-M6, M8, M10, njll., ebonisa ububanzi ngamamilimitha.Amabhawodi e-Imperial ngokuvamile amakwa nge-fraction noma inombolo elandelwa ngokuthi “UNC” (Unified National Coarse) noma “UNF” (Unified National Fine), okubonisa indinganiso yochungechunge.

2. Iphimbo lochungechunge: Ikala ibanga phakathi kwemicu.Uma isilinganiso singamamilimitha, cishe yi-metric bolt.Uma isilinganiso sikuchungechunge ngentshi ngayinye (TPI), cishe ibholithi yombuso.

3. Izimpawu zasekhanda: Amanye amabhawodi angase abe nezimpawu emakhanda awo ukuze abonise ibanga noma izinga lawo.Isibonelo, ama-metric bolt angase abe nokumaka okufana no-8.8, 10.9, noma 12.9, kuyilapho amabhawodi ombuso angase abe nezimpawu ezinjengokuthi “S” noma ezinye izimpawu zebanga zamabhawodi esakhiwo.

Ngokucabangela lezi zici, ungakwazi ukunquma ukuthi ibhawudi iyimethrikhi noma i-imperial.
