8.8 qib tooj dag hexagonal non-standard pob taub hau ntsia liaj qhov rooj

8.8 qib tooj dag hexagonal non-standard pob taub hau ntsia liaj qhov rooj yog ib qho tshwj xeeb tsim fastener nrog lub taub hau kheej kheej, uas ua rau nws muaj qee qhov kev hloov pauv thiab kev hloov pauv muaj peev xwm thaum txuas cov khoom siv tshuab. Pob taub hau bolts feem ntau yog siv rau kev sib txuas uas yuav tsum tau hloov kho lub kaum ntse ntse thiab hloov tau yooj yim, vim lawv lub taub hau kheej kheej tuaj yeem tig thiab tig nyob rau hauv ib qho kev sib txuas, muab txoj kev sib txuas yooj yim dua.
8.8 qib tooj dag hexagonal non-standard pob taub hau ntsia liaj qhov rooj yog dav siv nyob rau hauv ntau yam teb vim lawv zoo heev corrosion kuj, hluav taws xob conductivity, thiab thermal conductivity. Piv txwv li, hauv kev lag luam kev sib txuas lus xws li cables, khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, tooj dag yog siv dav vim nws cov khoom zoo. Tsis tas li ntawd, vim qhov kev ntxhib los mos ntawm tooj dag, cov xov ntawm lub workpiece tsis yooj yim puas tom qab rov qab disassembly, ua rau nws tsim nyog rau cov xwm txheej uas yuav tsum tau nquag disassembly thiab sib dhos.
Lub zog qib ntawm 8.8 qib tooj dag hexagonal tsis yog tus qauv pob lub taub hau ntsia liaj qhov rooj feem ntau yog siab, nrog rau qib sib zog xws li 8.8 thiab 10.8. Cov bolts muaj zog no tuaj yeem tiv taus cov khoom loj thiab tsim nyog rau kev fastening yuav tsum nyob rau hauv ntau yam khoom siv. Tsis tas li ntawd, cov khoom siv tooj dag muaj tus nqi qis, tab sis nws lub zog thiab hardness siab, ua rau nws nrov heev hauv kev lag luam fastener.
