Khoom Taw qhia
Lub zog qib ntawm carriage bolts raug xaiv raws li kev ua haujlwm siab. Cov qib kev ua tau zoo ntawm carbon steel carriage bolts yog 3.6, 4.6 thiab 4.8. Tus qauv tuaj yeem xa mus rau GB3098.1, thaum cov khoom siv ntawm cov hlau tsis muaj steel carriage bolts feem ntau yog austenitic stainless hlau, uas muaj cov cua sov zoo, zoo corrosion kuj thiab zoo weldability. Austenitic stainless hlau muaj xws li A1, A2. A4 thiab A2 thiab A4 stainless hlau yog feem ntau siv hauv khw, xws li SUS304 thiab SUS316. Ob leeg SUS304 thiab SUS316 muaj qhov zoo ductility thiab yooj yim los ua kom txias. Lawv yog cov tsis-magnetic nyob rau hauv ib txwm tej yam kev mob. 304 yog sib nqus me ntsis tom qab ua haujlwm txias, 316 yog me ntsis sib nqus dua 304 tom qab ua haujlwm txias.

Daim Ntawv Thov Cheeb Tsam ntawm Qib 8.8 Carriage Bolt
Daim ntaub ntawv ntawm square neck carriage bolts tsis loj heev. Piv txwv li, GB12 carriage bolts zoo ib yam li DIN603 carriage bolts. Lawv feem ntau yog siv rau hauv grooves. Thaum zawm, lub bolt pas nrig yuav tsis tig vim kev ua haujlwm ntawm lub caj dab square, uas yooj yim rau kev kho thiab txhim kho. Lub log tsheb tuaj yeem txav mus rau qhov sib npaug hauv qhov chaw. Txij li thaum lub taub hau ntawm lub tsheb thauj khoom yog puag ncig, tsis muaj kev tsim cov cuab yeej siv hluav taws xob xws li hla grooves lossis hexagon sockets, thiab nws kuj tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv tub sab hauv kev sib txuas tiag tiag.
Lub tsheb thauj khoom yog siv rau qee lub sijhawm tshwj xeeb vim nws qhov tshwj xeeb, xws li txee, txee thiab lwm qhov chaw.
