Product Description
Square taub hau bolts yog threaded fasteners nrog lub taub hau square, muaj ib lub taub hau square thiab threaded shank. Lawv cov xwm txheej tshwj xeeb- lub taub hau tsim muab thaj chaw sib txuas loj dua rau cov wrenches, muab kev tiv thaiv plam, yooj yim ntawm daim ntawv thov, thiab kev sib kis tau zoo. Lawv yog tshwj xeeb tshaj yog haum rau fastening daim ntaub ntawv nyob rau hauv hnyav-lub luag hauj lwm machinery, steel qauv, railways, thiab petrochemical industries- ib puag ncig yam ntxwv los ntawm hnyav loads, siab vibration, thiab hnyav tej yam kev mob.
