Liboutu tse hexagonaldi sebedisoa ho kopanya dikarolo tsa tshepe mmoho. Hangata li sebelisoa kahong, mochining le lits'ebetsong tsa likoloi. Hlooho ea hex ea bolt e lumella ho tiisa le ho lokoloha habonolo ka wrench kapa sokete, e etsa hore e be khetho e tsebahalang ea ho boloka likarolo tse boima.

Ho lekanya bolt ea metric, o hloka ho tseba bophara, bophahamo le bolelele.

1. Diameter: Sebelisa caliper ho lekanya bophara ba bolt. Ka mohlala, haeba ke M20 bolt, bophara ke 20mm.

2. Tsela ea khoele: Sebelisa sekala sa molumo ho lekanya sebaka se pakeng tsa likhoele. Sena se tla u thusa ho tseba hore na mohala oa khoele ke ofe, o bohlokoa bakeng sa ho bapisa bolt le nate e nepahetseng.

3. Bolelele: Sebelisa rula kapa tekanyo ea theipi ho lekanya bolelele ba bolt ho tloha tlase hloohong ho isa ntlheng.

Ka ho metha likarolo tsena tse tharo ka nepo, o ka tseba le ho khetha bolt ea metric e nepahetseng bakeng sa ts'ebeliso ea hau e ikhethileng.

"TPI" e emetse "khoele ka inch." Ke tekanyo e sebelisetsoang ho bontša palo ea likhoele tse teng ka har'a boutu ea lisenthimithara tse le 'ngoe. TPI ke lintlha tsa bohlokoa tse lokelang ho nahanoa ha u bapisa liboutu le linate kapa u khetha ho lumellana ha likaroloana. Mohlala, bolt ea 8 TPI e bolela hore boutu e na le likhoele tse 8 tse felletseng ka inch e le 'ngoe.

Ho tseba hore na bolt ke metric kapa imperial, o ka latela litataiso tsena tse akaretsang:

1. Sistimi ea ho lekanya: Sheba matšoao a liboutu. Hangata liboutu tsa metric li tšoauoa ka tlhaku “M” e lateloang ke nomoro, joalo ka M6, M8, M10, joalo-joalo, e bontšang bophara ba limilimithara. Hangata liboutu tsa Imperial li tšoauoa ka karoloana kapa palo e lateloang ke “UNC” (Unified National Coarse) kapa “UNF” (Unified National Fine), e bontšang mokhoa oa khoele.

2. Thread pitch: E lekanya sebaka se pakeng tsa likhoele. Haeba tekanyo e le ka limilimithara, mohlomong ke metric bolt. Haeba tekanyo e le ka likhoele ka inch (TPI), e kanna ea ba bolt ea borena.

3. Matšoao a hlooho: Liboutu tse ling li ka ’na tsa e-na le matšoao lihloohong tsa tsona ho bontša mophato oa tsona kapa maemo a tsona. Mohlala, metric bolt e kanna ea ba le matšoao a joalo ka 8.8, 10.9, kapa 12.9, athe liboutu tsa borena li kanna tsa ba le matšoao a kang "S" kapa matšoao a mang a mophato bakeng sa liboutu tsa meralo.

Ka ho nahana ka lintlha tsena, u ka tseba hore na bolt ke metric kapa ea borena.
