Hexagon Socket Head Cap Bolt DIN 912

Txhais thiab cov yam ntxwv ntawm cov qauv

Lus Txhais: Ib qho ntsia hlau sab hauv hexagonal yog lub fastener nrog hexagonal groove (internal hexagonal qhov) ntawm lub taub hau, uas yuav tsum tau siv lub Allen Key los yog lub taub hau hexagonal screwdriver nrog ib lub cuab yeej hluav taws xob rau kev teeb tsa thiab tshem tawm.

Khoom nta:

Lub taub hau hom: hom cylindrical taub hau (xws li ISO 4762 / DIN 912), countersunk taub hau (xws li DIN 7991), lub taub hau tiaj tus, thiab lwm yam, haum rau cov kev xav tau sib txawv (xws li lub taub hau countersunk siv nyob rau hauv qhov xwm txheej uas yuav tsum muaj qhov dej ntws).

Xov hom: tag nrho xov los yog ib nrab xov, nrog ntau yam ntaub ntawv thiab kev kho deg

Khoom siv thiab kev kho deg

Cov khoom siv:

Carbon steel (xws li 8.8 qib, 12.9 qib): siab zog, siv nyob rau hauv machinery thiab tsheb.

Stainless hlau (304/316): corrosion-resistant, haum rau sab nraum zoov thiab kho khoom siv.

Titanium alloy: hnav, siab corrosion kuj, siv nyob rau hauv aerospace.

Daim ntawv thov scenarios

Kev lag luam teb: cov cuab yeej siv tshuab, pwm, cov cuab yeej siv automation (cov kev sib txuas muaj zog uas yuav tsum tau nquag disassembly).

Automotive / Aviation: Cav Cheebtsam, chassis (siab kub tsis kam, kev co kuj).

Consumer electronics: laptops, cameras (precision me me screws, xws li M1.6).

Rooj tog / Tsheb kauj vab: IKEA rooj tog sib dhos, tsheb kauj vab nres system (countsunk anti scratch)

Cov lus qhia siv:

Lub ciaj ntswj yuav tsum tau muab tso rau hauv qab ntawm lub qhov kom tsis txhob zawv zawg cov hniav los ntawm oblique quab yuam.

Thaum ua ntej drilling, countersunk screws yuav tsum phim lub taper (xws li 90 °).

Tsis tu ncua xyuas lub torque (siv lub torque ciaj ntswj) kom tsis txhob dhau nruj los yog loosening.
