Specifications Thiab Specification Table Ntawm Qhov (Socket Head Cap) Bolts

Lub qhov (socket head cap bolts).yog cov fasteners feem ntau nyob rau hauv cov neeg kho tshuab teb, thiab muaj ntau yam kev xav rau lawv specification xaiv thiab yuav khoom. Cov hauv qab no yog cov kev xav tau tshwj xeeb thiab cov ntsiab lus tseem ceeb ntawm lub qhov (socket head cap bolts), muab kev siv rau kev yuav khoom thiab siv.

I. Core Specification Requirements ntawm Socket Head Cap Bolts

Cov lus qhia tshwj xeeb ntawm lub qhov (socket) lub taub hau taub hau bolts yuav tsum ua raws li cov txheej txheem meej meej, feem ntau suav nrog cov hauv qab no:

1. Lub qhov (socket hexagon) lub qhov ncauj tso cai rau ua kom sib npaug los yog counterbored.

2. Xaus chamfer: Lub taub hau taub hau bolts nrog xov specification d Tsawg dua los yog sib npaug rau M4 txais yuav dov kawg.

Qhov ntev ntawm cov xov tsis tiav U Less dua los yog sib npaug rau 2P (P yog lub suab) kom ntseeg tau tias kev ua haujlwm ntawm cov xov txuas.

4. Sab saum toj ntawm lub taub hau ntsia liaj qhov rooj tuaj yeem tsim los ua ib puag ncig ntug lossis chamfer ntawm cov chaw tsim khoom xaiv.

5. Cov ntug hauv qab ntawm lub taub hau ntsia liaj qhov rooj tuaj yeem tsim los ua ib puag ncig ntug lossis chamfered rau Dw (lub taub hau txoj kab uas hla), tab sis tsis muaj burrs raug tso cai nyob rau hauv ob qho tib si tsim kom tsis txhob cuam tshuam kev sib dhos.

6. Cov qauv tsim hauv lub tebchaws rau lub qhov (socket) lub taub hau taub hau bolts: GB / T 2672 (Socket Head Cap Bolts, Ib Nrab Xov), GB / T 2673 (Socket Head Cap Bolts, Tag Nrho Xov), GB / T 2674 (Countersunk Head Socket Cap Bolts), GB / T 6190 (Socket Head Cap Bolts, 1 GBT), Fine Bolts, Fine Thread), thiab lwm yam. Thaum yuav khoom, xaiv raws li qhov xav tau tiag tiag nrog rau cov qauv siv.

II. Imperial Specifications ntawm Lub Taub Hau Lub Taub Hau Bolts

Cov specifications ntawmlub qhov (socket head cap bolts).tuaj yeem muab faib raws li qhov system imperial. Lub imperial system siv ntiv tes ua chav tsev, nrog rau qhov pib faib ntawm 1 nti muab faib ua 8 ntu, txhua ntu hu ua 1 "fen". Piv txwv li, 1/8 nti yog hu ua 1-fen bolt, 1/4 nti yog hu ua 2-fen bolt, thiab 1/2 nti yog hu ua 4-fen bolt.

Ntxiv rau qhov kev faib tawm ntawm 1/8 nti, bolts raws li 1/16 nti kuj tuaj yeem yuav hauv khw muag khoom, piv txwv li, 3/16 nti yog hu ua ib nrab-fen bolt.

Imperial specifications yog txheeb los ntawm me me mus rau loj loj. Zoo li cov metric bolts, imperial bolts kuj siv lub taub hau taub hau raws li qhov ntsuas qhov tseem ceeb, tab sis ntxiv ib qho ntxiv "cov hniav suav" (txog rau suab) parameter - cov hniav suav hais txog cov xov tooj ntawm ib nti ntawm qhov ntev. Feem ntau, qhov loj ntawm lub ntsia liaj qhov taub txoj kab uas hla, qhov tsawg dua cov hniav suav. Tsis tas li ntawd, cov hniav suav ntawm imperial bolts tau muab faib ua cov hniav ntxhib thiab cov hniav zoo, uas yuav tsum tau xaiv raws li qhov yuav tsum tau ua thiab cov xwm txheej sib dhos.

Ob lub imperial thiab metric bolts tau qhia hauv "inch + ntev", tab sis lawv muaj cov hauv paus sib txawv (1 nti ≈ 25.4 millimeters). Lawv tuaj yeem paub meej meej hauv kev sau ntawv, tab sis tsis tuaj yeem hloov pauv hauv kev siv tswv yim, txwv tsis pub nws yuav ua rau muaj kev sib txuas tsis zoo, tsis muaj peev xwm sib sau ua ke thiab lwm yam teeb meem.

III. Cov ntsiab lus

Kev nkag siab zoo txog cov kev cai tshwj xeeb ntawm lub qhov (socket head)cap boltsthiab qhov sib txawv ntawm imperial thiab metric systems yog qhov tseem ceeb rau kev nkag siab, kev yuav khoom thiab siv lub qhov (socket head cap bolts). Tsuas yog los ntawm kev paub zoo txog lawv cov qauv kev qhia tshwj xeeb thiab cov yam ntxwv ntawm kev faib tawm tuaj yeem ua rau peb raug yuav thiab siv tus qauv siv, muab kev ua si tag nrho rau cov nyhuv fastening ntawm lub qhov (socket head cap bolts), thiab xyuas kom muaj kev sib txuas ruaj khov ntawm cov khoom siv lossis cov qauv.
