Hexagon bolts tiag tiag xa mus rau fasteners uas muaj lub taub hau nrog lub hau. Bolts feem ntau muab faib ua hlau bolts thiab stainless hlau bolts raws li cov khoom siv. Hlau muab faib ua qib, nrog rau cov qib sib xws yog 4.8, 8.8, thiab 12.9. Stainless hlau yog ua los ntawm stainless hlau SUS201, SUS304, thiab SUS316 bolts.
Ib qho ua tiav ntawm hexagon bolts muaj lub taub hau ntsia liaj qhov rooj, lub txiv ntoo, thiab lub tiaj tus gasket.
Hexagon taub hau bolts yog hexagonal taub hau bolts (ib nrab threads) - c hexagonal taub hau bolts (tag nrho threads) - c qib, tseem hu ua hexagonal taub hau bolts ( ntxhib) hexagonal taub hau bolts, dub hlau screws. Cov qauv siv feem ntau yog: sh3404, hg20613, hg20634, thiab lwm yam.
Hexagon taub hau ntsia liaj qhov rooj (abbreviated li hexagon bolt) muaj ib lub taub hau thiab ib tug threaded pas nrig (
Cov qib kev ua tau zoo ntawm bolts siv rau kev sib txuas ntawm cov qauv hlau tau muab faib ua ntau tshaj 10 qib, suav nrog 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, thiab 12.9. Ntawm lawv, bolts ntawm qib 8.8 thiab siab dua, uas yog ua los ntawm cov hlau tsis tshua muaj carbon hlau lossis cov pa roj carbon nruab nrab thiab tau txais kev kho cua sov (quenching thiab tempering), feem ntau hu ua bolts siab zog, thaum tus so feem ntau raug xa mus. zoo li qub bolts. Cov qhab nia qib qhab nia muaj ob feem ntawm cov lej uas sawv cev rau tus nqi nominal tensile lub zog thiab cov txiaj ntsig piv ntawm cov khoom siv ntsia liaj qhov rooj. Hauv qab no yog ib qho piv txwv.
Lub ntsiab lus ntawm bolts nrog qib kev ua tau zoo ntawm 4.6 yog:
Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 400 mpa;
2. Lub zog sib piv ntawm cov khoom siv ntsia liaj qhov rooj yog 0.6;
3. Nominal yield zog ntawm bolt khoom mus txog 400 × 0.6 = 240MPa qib
Lub zog muaj zog bolts nrog qib kev ua tau zoo ntawm 10.9, thiab cov khoom siv tom qab kev kho cua sov mus txog:
1. Lub nominal tensile lub zog ntawm bolt khoom ncav cuag 1000MPa;
2. Lub zog ntawm qhov sib piv ntawm cov khoom siv ntsia liaj qhov rooj yog 0.9;
Lub nominal yield zog ntawm bolt khoom ncav cuag 1000 × 0.9 = 900MPa qib
Lub ntsiab lus ntawm cov qib sib txawv ntawm kev ua haujlwm bolt yog ib qho kev lees paub thoob ntiaj teb. Bolts nrog tib qib kev ntsuas kev ua tau zoo muaj qhov ua tau zoo ib yam tsis hais lawv cov khoom siv thiab keeb kwm, thiab tsuas yog qib kev nyab xeeb kev ua tau zoo tuaj yeem raug xaiv rau kev tsim.
