Peb DIN7991 countersunk socket head cap bolts rau steel siv, machinery thiab khoom siv. Peb cov khoom siv npog M3-M24 hauv 8.8/10.9/12.9 alloy steel thiab A2/A4 stainless, nrog DIN7991/ISO10642 dimension tswj, nruj qhov (socket) loj soj ntsuam, thiab kuaj cov qib zog. Txawm hais tias koj tab tom tsim lub thav duab steel uas yuav tsum tau tshem tawm, mounting machinery guards los yog assembling aluminium extrusion nyob rau hauv ib lub teeb - steel txoj hauj lwm, peb muaj peev xwm xa qhov loj thiab qib nyob rau hauv lub sij hawm txheem.
Vim li cas thiaj xaiv Countersunk Socket Head Cap Bolt?
Lub qhov (socket) lub taub hau taub hau ntsia liaj qhov rooj (DIN7991 / ISO10642) yog txoj kev huv tshaj plaws los kho lub hau npog, tiv thaiv, vaj huam sib luag lossis trim flush tiv thaiv nws qhov chaw. Nws 90℃tiaj tus taub hau lub rooj zaum nrog lub ntsej muag ua haujlwm, lub qhov (socket) sab hauv hexagon tsav los ntawm ncaj qha saum toj no, thiab qhov sib koom ua tiav nyob twj ywm tiaj tus, snag-dawb thiab pom kev zoo. Ntawm no yog vim li cas lub qhov (socket) countersunk tau txais nws qhov chaw hla lub hex lossis khawm taub hau qhov twg qhov chaw tiaj tus, kev nyab xeeb thiab qhov teeb meem tshwm sim:
Flush, Snag-Dawb Nto
Lub tiaj tus 90℃lub taub hau ploj mus nrog qhov chaw, yog li npog, tiv thaiv, panels thiab zawv zawg qhov chaw nyob tas li - tsis muaj dab tsi protrudes mus ntes khaub ncaws, cuab yeej, cables lossis txav mus.
Hex Socket Drive - Sab saum toj Mounting & Anti-Strip
Ib qho tseem ceeb Allen koom los ntawm ncaj qha saum toj no, zoo tagnrho rau cov pob qij txha recessed los yog nruj qhov twg ib tug ciaj ntswj mus txog. Precise qhov (socket) loj thiab chamfer txo tus yuam sij rounding ntawm tus tsav.
Engineered Head Geometry Uas Muaj Tseeb
Lub taub hau txoj kab uas hla, qhov siab thiab 90℃lub kaum sab xis yog tuav rau DIN7991 / ISO10642, yog li lub hau ntswj zaum dej ntws thiab perpendicular nyob rau hauv lub qhov countersunk es tsis txhob co.
Kev xaiv muaj zog rau txhua qhov Load
8.8 rau kev siv dav dav, 10.9 / 12.9 alloy rau siab dua torque thiab me me - loj zog, thiab stainless A2 / A4 qhov twg corrosion los yog kev tu cev tseem ceeb - tag nrho cov kev ntsuam xyuas raws li ISO 898-1 / ISO 3506.
Huv si, Tamper-Kev sib dhos zais
Rau lub qhov rooj kaw, nkag mus rau vaj huam sib luag thiab trim, lub taub hau yaug zais qhov chaw kho - cov kab huv huv thiab tsawg dua kom ntes lossis puas tsuaj ntawm cov khoom tiav.
Ib puag ncig -Matched Finishes
Zinc rau sab hauv tsev, Dacromet / HDG los yog stainless A4 rau sab nraum zoov thiab maritime, dub oxide rau tooling - coated los yog passivated raws li koj xav tau kev siv.

Installation & Socket Torque Guide
1. Sib phim lub qhov (socket) loj
Siv tus yuam sij Allen kom raug (xws li M6 → 4mm, M8 → 5mm, M10 → 6mm) rau tag nrho, tsis yog - swb tsav.
2. Ntev npaum li cas ntsuas
Rau ib tug metric countersunk ntsia hlau lub nominal ntev muaj xws li lub taub hau. Xov pib hauv qab lub taub hau, yog li kev tuav tau zoo=nominal length minus head height.
3. Tsav torque / sawb tiv thaiv
Siv qhov pom zoo torque rau qib; tshaj - tsav lub taub hau nyias nyias tuaj yeem hloov lub qhov (socket) - thaum tsis ntseeg, siv 12.9 alloy rau qhov me me.
Ntim, Lead Time & Shipping
Export -qib ntim, lub sij hawm ua cov hmoov txhuas thiab hloov tau yooj yim shipping rau koj lub qhov (socket) lub taub hau taub hau ntsia liaj qhov rooj txiav txim - nrog rau tag nrho cov ntaub ntawv xa tuaj ntawm kev thov.

FAQ:
Puas yog DIN7991 zoo ib yam li ISO10642?
ISO10642 hloov DIN 7991 rau metric countersunk socket screws; feem ntau qhov ntau thiab tsawg yog interchangeable. Peb muab rau tus qauv raws li koj teev.
Vim li cas kuv tus yuam sij Allen plam ntawm qhov ntsia hlau?
Feem ntau yog lub qhov (socket) hnav, qhov loj me yuam kev, lossis dhau -torque. Siv tus yuam sij sib piv (saib cov lus) thiab, rau cov kab me me, 12.9 alloy resists qhov sib npaug.
Cov no puas haum rau cov qauv hlau?
Tsis muaj - countersunk conical taub hau yog rau flush/aesthetic thiab nruab nrab -load siv. Rau cov qauv kev sib txuas peb muab DIN931/933 hex bolts thiab TS siab -lub zog bolts.
Koj puas muab M24 nrog lub taub hau 60 degree?
Yog lawm, M24 nyob rau hauv 60℃ca taub hau ib DIN7991 dimension rooj yog muaj nyob rau ntawm kev txiav txim.
