Allen taub hau screws, tseem hu ua hex socket screws, yog ib hom fastener uas nta ib tug hexagonal so nyob rau hauv lub taub hau. Qhov chaw so no yog tsim los siv nrog Allen wrench lossis hex key, uas muab lub zog ntxiv thiab kev tswj xyuas thaum zawm lossis loosening cov ntsia hlau.
Ntawm Ningbo Zhenkun Machinery Co., Ltd., peb muab ntau yam Allen taub hau screws nyob rau hauv ntau qhov ntau thiab tsawg thiab cov ntaub ntawv, suav nrog stainless hlau thiab carbon hlau. Peb cov ntsia hlau yog tsim los ua kom tau raws li DIN, ANSI, thiab GB cov qauv, ua kom lawv ntseeg tau thiab zoo.
Cov ntsia hlau no feem ntau siv rau ntau yam kev siv, xws li tshuab, tsheb, kev tsim kho, thiab hluav taws xob. Lawv muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov uas yuav tsum muaj kev ruaj ntseg thiab nruj, vim tias lub hexagonal recess tiv thaiv lub hau ntswj los ntawm lub taub hau.
Ib qho ntawm qhov zoo ntawm Allen lub taub hau screws yog lawv lub peev xwm los tiv thaiv qib siab ntawm torque yam tsis muaj stripping lossis rounding tawm lub taub hau. Tsis tas li ntawd, lawv cov qauv tsim ua kom yooj yim nkag mus rau qhov chaw nruj, ua rau lawv xaiv qhov zoo tshaj plaws rau ntau daim ntawv thov sib txawv.
