2H txiv ntseej yog cov khoom siv zoo, hnyav hnyav uas tau siv dav hauv kev siv tshuab thiab kev lag luam.Ua los ntawm forged carbon steel, cov txiv ntoo no yog tsim los tiv taus cov loads siab thiab muab kev ua tau zoo ib yam nyob rau hauv qhov chaw huab cua tshaj plaws.
Nrog nws cov chav kawm tshwj xeeb 2H hardened lub zog, cov txiv ntoo no muaj lub zog tsis sib xws thiab ua haujlwm ntev tshaj li tus qauv DIN thiab ISO specifications.Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv cov khoom hnyav uas muaj kev nyab xeeb thiab kev ntseeg siab yog qhov tseem ceeb, xws li hauv kev tsim kho, mining, thiab roj thiab roj kev lag luam.
2H txiv ntseej nta cov duab hexagonal uas ua rau nws yooj yim rau nruab siv tus qauv ciaj ntswj lossis lub qhov (socket).Nws compatibility nrog tus qauv threaded bolts thiab screws kuj ua rau nws muaj ntau yam kev daws teeb meem rau ntau yam kev siv.
Ntxiv rau nws lub zog tshwj xeeb thiab ua haujlwm ntev, 2H txiv ntoo kuj tseem tiv taus corrosion thiab xeb.Qhov no ua rau nws haum rau siv nyob rau hauv ib puag ncig hnyav uas raug cov dej noo thiab tshuaj lom neeg.
Ua tau raws li cov qauv zoo tshaj plaws, 2H txiv ntseej tau dhau los ua kev sim thiab tshuaj xyuas kom ntseeg tau tias nws ua tau raws li kev lag luam xav tau.Nrog nws cov kev ua tau zoo, kev ua haujlwm ntev, thiab kev teeb tsa yooj yim, 2H txiv ntseej yog qhov tseem ceeb rau txhua daim ntawv thov kev lag luam hnyav.
Txawm hais tias koj yuav tsum tau ceev cov cuab yeej hnyav, tshuab, lossis cov qauv, 2H txiv ntoo yog qhov kev daws teeb meem zoo tshaj plaws uas muab lub zog tsis sib xws, ua haujlwm ntev, thiab kev nyab xeeb.
