Dab tsi yog qhov txawv ntawm lub txiv ntseej thiab lub bolt?

1. Qhov txawv ntawm cov duab:
Lub txiv ntseej yog hexagonal lossis octagonal threaded ib feem nrog ntau-faceted zoo, feem ntau yog siv nrog bolts lossis screws. Ib lub txiv ntoo, ntawm qhov tod tes, yog ib qho cylindrical threaded ib feem nrog ib puag ncig lossis hexagonal duab, feem ntau siv nrog ib tug threaded pas nrig.

2. Qhov txawv ntawm Kev Ua Haujlwm:
Lub luag haujlwm tseem ceeb ntawm cov txiv ntoo yog kom ruaj ntseg bolts los yog screws, tiv thaiv lawv los ntawm loosening los yog poob tawm. Nws yog feem ntau siv los ua ib qho fastener hauv kev sib txuas tshuab, xws li hauv tsheb thiab tshuab. Lub luag haujlwm tseem ceeb ntawm cov txiv ntseej yog los kho qhov ntev ntawm cov hlua khi, ua kom muaj kev sib txuas nruj nrog lwm qhov chaw. Nws yog feem ntau siv hauv kev tsim kho, txuas hniav, thiab lwm yam.

3. Qhov sib txawv ntawm cov khoom siv:
Cov txiv ntoo thiab txiv ntoo kuj yog ua los ntawm cov khoom sib txawv. Cov txiv ntseej feem ntau yog ua los ntawm cov hlau tsis muaj steel, stainless hlau, tooj dag, thiab lwm yam, muab lub zog siab thiab corrosion kuj. Cov txiv ntseej feem ntau yog ua los ntawm hlau, tooj liab, txhuas, thiab lwm yam, muab cov thermal thiab hluav taws xob conductivity zoo dua.

4. Qhov sib txawv ntawm daim ntawv thov:
Txiv ntseej thiab txiv ntseej yog siv rau hauv ntau daim ntawv thov. Cov txiv ntseej feem ntau yog siv rau hauv cov khoom sib txuas uas xav tau lub zog siab thiab corrosion kuj, xws li hauv tsheb thiab tshuab. Cov txiv ntseej feem ntau yog siv rau hauv daim ntawv thov uas yuav tsum tau ua kom zoo thermal thiab hluav taws xob conductivity, xws li cov khoom siv hluav taws xob, cov tsev, thiab txuas hniav.
