Sab hauvhex qhov (socket) boltsyog cov fasteners ib txwm, tab sis kev nkag siab thiab xaiv cov ntsiab lus tseem ceeb heev. Hauv qab no, peb yuav qhia txog cov kev qhia tshwj xeeb ntawm sab hauv hexagonal bolts thiab cov lus ntawm sab hauv hex socket bolts specifications.
Internal hex socket bolts specifications
Kev txiav txim siab ntawm cov lus qhia tshwj xeeb rau hex socket bolts suav nrog cov hauv qab no:
1. Lub puab hexagonal lub qhov ncauj tso cai rau qhov chaw ntawm pins, uas yuav tsum tau chamfered los yog countersunk.
2. Qhov kawg chamfer d<=M4 is the rolled end.
3. Qhov ntev ntawm cov xov tsis tiav U<=2P.
4. Sab saum toj ntug ntawm lub taub hau tuaj yeem yog puag ncig lossis chamfered, ntawm kev txiav txim siab ntawm cov chaw tsim khoom.
5. Cov ntug hauv qab tuaj yeem yog puag ncig lossis chamfered rau Dw, tab sis yuav tsum tsis muaj burrs.
6. Cov qauv rau sab hauv hex socket bolts suav nrog GB / T2672, GB / T2673, GB / T2674, GB / T6190, thiab GB / T6191.
Specification ntawmhexagon socket boltsnyob rau hauv lus Askiv system
Cov lus qhia tshwj xeeb ntawm hex socket bolts tuaj yeem txheeb xyuas raws li qhov system imperial, uas yog raws li ntiv tes thiab muab faib ua 8 qhov sib npaug ntawm 1 nti, hu ua 1 feeb. Piv txwv li, 1/8, 1/4, 1/2, thiab lwm yam yog hu ua 1/2, 2/4 screws. Ntxiv rau kev siv 1/8 nti ua lub hauv paus, screws nrog 1/16 nti raws li lub hauv paus kuj tuaj yeem yuav hauv khw muag khoom, piv txwv li, 3/16 yog hu ua cov ntsia hlau sib cais.
Kev txheeb xyuas ntawm imperial screws yog ua tiav nyob rau hauv qhov kev txiav txim nce mus, thaum ob qho tib si metric thiab imperial screws yog ntsuas los ntawm cov ntsia hlau txoj kab uas hla, tab sis imperial screws muaj cov hniav ntau dua. Cov hniav pitch ntawm cov ntsia hlau yog xam raws li tag nrho cov hniav ib nti ntawm qhov ntev. Qhov loj ntawm cov ntsia hlau txoj kab uas hla, cov hniav tsawg dua. Tsis tas li ntawd, cov hniav pitch ntawm British screws raug faib ua ob hom: cov hniav ntxhib thiab cov hniav hluas.
Ob lub imperial thiab metric screws yog qhia nyob rau hauv cov nqe lus ntawm cov ntsia hlau taub thiab ntev, thaum 1 nti yog kwv yees li ntawm 25.2 millimeters. Vim hais tias cov lej ntawm cov lus Askiv thiab metric screws sib txawv, lawv tuaj yeem sau tau hauv kev sau ntawv, tab sis tsis tuaj yeem hloov pauv hauv kev siv tswv yim.
Hauv cov ntsiab lus, nkag siab qhov tshwj xeeb ntawm hex qhov (socket) bolts thiab lub rooj ntawmhex qhov (socket) boltsspecifications yog heev pab tau rau peb to taub thiab xaiv hex socket bolts. Tsuas yog los ntawm kev paub txog cov kev qhia tshwj xeeb thiab kev faib tawm tuaj yeem peb xaiv tau zoo dua thiab siv hex socket bolts kom ua tiav cov txiaj ntsig zoo dua.
