1. Lub Npe
Cov ntsia hlau cylindrical head hexagon socket head, tseem hu ua hexagon socket head bolts, cup head screws, thiab hexagon socket head screws, muaj lub npe sib txawv, tab sis lawv txhais tau tib yam. Cov ntsia hlau hexagon socket head uas siv ntau suav nrog qib 4.8, qib 8.8, qib 10.9, thiab qib 12.9. Kuj hu ua hexagon socket screws, tseem hu ua hexagon socket bolts. Lub taub hau yog lub taub hau hexagonal lossis lub taub hau cylindrical.

2. Khoom siv
Cov hlau carbon thiab cov hlau tsis xeb.
Cov hlau carbon hex socket taub hau ntsia hlau muaj cov yam ntxwv ntawm lub zog siab thiab tus nqi qis, thiab yog cov khoom siv pheej yig thiab siv tau. Nws yog siv rau qee qhov chaw, xws li cov khoom sim qis, cov khoom siv niaj hnub, rooj tog, kev tsim cov qauv ntoo, tsheb kauj vab, maus taus, thiab lwm yam.
Cov hlau tsis xeb muaj cov yam ntxwv ntawm kev tiv taus corrosion, tiv taus kub siab thiab zoo toughness, thiab feem ntau siv los ua cov ntsia hlau thiab txiv ntoo uas xav tau ntau. Cov ntsia hlau stainless hlau hex socket yog siv dav hauv kev sib txuas cov khoom siv hauv kev lag luam tshuaj, zaub mov thiab lwm yam lag luam, nrog rau cov khoom siv tshuaj lom neeg, cov khoom siv hluav taws xob thiab lwm yam teb. Vim nws muaj zog tiv thaiv oxidation thiab tiv thaiv corrosion, nws tsis yooj yim oxidized thiab xeb los ntawm ib puag ncig, yog li nws tuaj yeem hloov kho rau qhov chaw ib puag ncig hnyav.

3. Cov Lus Qhia thiab Hom

Tus lej txheem ntawm lub teb chaws ntawm cov ntsia hlau hexagonal socket taub hau yog GB70-1985. Muaj ntau yam lus qhia thiab qhov loj me. Cov lus qhia thiab cov qauv siv feem ntau yog 3 * 8, 3 * 10, 3 * 12, 3 * 16, 3 * 20, 3 * 25, 3 * 30, 3 * 45, 4 * 8, 4 * 10, 4 * 12, 4 * 16, 4 * 20, 4 * 25, 4 * 30, 4 * 35, 4 * 45, 5 * 10, 5 * 12, 5 * 16, 5 * 20, 5 * 25, 6 * 12, 6 * 14, 6 * 16, 6 * 25, 8 * 14, 8 * 16, 8 * 20, 8 * 25, 8 * 30, 8 * 35, 8 * 40, thiab lwm yam.

4. Kev Nyuaj Siab
Cov ntsia hlau hexagon socket raug faib ua pawg raws li qhov nyuaj ntawm cov hlau ntsia hlau, lub zog tensile, lub zog yield, thiab lwm yam. Cov khoom siv sib txawv xav tau cov qib sib txawv ntawm cov ntsia hlau hexagon socket kom phim lawv. Txhua lub ntsia hlau hexagon socket muaj cov qib hauv qab no:
Cov ntsia hlau hexagon socket head bolts muab faib ua cov ntsia hlau ib txwm thiab cov ntsia hlau muaj zog siab raws li lawv qib zog. Cov ntsia hlau hexagon socket bolts ib txwm yog qib 4.8, thiab cov ntsia hlau hexagon socket bolts muaj zog siab yog qib 8.8 lossis siab dua, suav nrog qib 10.9 thiab 12.9. Cov ntsia hlau hexagon socket head bolts chav kawm 12.9 feem ntau yog cov ntsia hlau dub hex socket head khob uas muaj roj pleev xim.
Cov qib kev ua tau zoo ntawm cov ntsia hlau hexagon socket siv rau kev sib txuas cov qauv hlau tau muab faib ua ntau dua 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, cov ntsia hlau qib 8.8 thiab siab dua yog ua los ntawm cov hlau tsis tshua muaj carbon lossis cov hlau carbon nruab nrab. Tom qab kev kho cua sov (quenching thiab tempering), lawv feem ntau hu ua cov ntsia hlau muaj zog siab, thiab lwm qhov feem ntau hu ua cov ntsia hlau ib txwm muaj. Daim ntawv lo qib kev ua tau zoo ntawm cov ntsia hlau muaj ob ntu ntawm cov lej, uas sawv cev rau tus nqi zog tensile nominal thiab qhov piv ntawm lub zog ntawm cov khoom siv ntsia hlau.
