Peb muaj peb tus kheej qhov chaw kho mob, thiab cov thickness ntawm zinc txheej ua tau raws li tus qauv yuav tsum tau ua.Peb tuaj yeem ua cov ntawv pov thawj kev soj ntsuam, suav nrog kev kho deg xws li kub galvanizing, Dacromet, electro galvanizing, boiling dub, thiab lwm yam.
Lub sab nrauv hexagon ntsia hlau yog cov txiv ntoo sib txuam siv los txuas thiab txuas ob qhov txuas nrog los ntawm qhov thiab cov khoom.Hex taub hau screws feem ntau siv bolts.Nws yog qhov tseem ceeb dua los siv Class A thiab Class B txheej hexagon.Tsis tas li ntawd, nws yog feem ntau siv nyob rau hauv lub ntees ntawm siab los ua ke raug, loj tej yam kev mob, kev co los yog hla tus nqi load.Qib C sab nrauv 66 screws yog siv nyob rau hauv cov xwm txheej uas qhov saum npoo yog ntxhib thiab tsis tas yuav tsum tau sib dhos qhov tseeb.
GB series, Q standard series, DIN German standard series, IFI American standard series, BS British standard series, JIS Japanese txheem series, ISO thoob ntiaj teb tus qauv series, thiab lwm yam.
Ib qho ntawm cov qauv rau hexagon bolts yog cov qauv qib, uas tau muab faib ua 4.8 thiab 8.8.Ob theem no tau siv ntau zaus hauv kev ua lag luam.Tshwj xeeb yog Qib 4.8 sab nrauv hexagon ntsia liaj qhov rooj.Vim tias nws pheej yig dua li qib 8.8 hex bolts.Tau kawg, nws yog siv ntau dua.Tab sis rau cov khoom uas muaj kev xav tau siab.Vim nws cov kev xav tau siab hauv hardness thiab lwm yam.
Cov khoom siv los ntawm cov chaw tsim khoom hlau zoo, uas tuaj yeem muab cov ntaub ntawv pov thawj kev tshuaj xyuas, suav nrog Q235, 35 #, 45 #, 345B, 40Cr, 35CrmoA, stainless hlau 201, 304 thiab lwm yam ntaub ntawv tshwj xeeb.
Qhov no yuav tsum tau siv qib 8.8 hex bolts.Qib 8.8 sab nraud hexagon ntsia liaj qhov rooj yog qhov nyuaj ntawm cov hardness thiab ntsia hlau torque.Nws muaj kev nyab xeeb dua los siv cov khoom.Ceev thiab ruaj khov dua.
