Product Overview
Khob lub taub hau ntswj ntsia hlau (Allen screws) muaj lub taub hau cylindrical nrog rau sab hauv hexagon tsav, tsim los rau siab-torque fastening nrog Allen cov yawm sij. Manufactured rauGB/T 70.1-2008, sib npaug rau ISO 4762 thiab dimensionally sib xws nrog DIN 912, cov no yog Qib A precision metric fasteners.
Muaj nyob rau hauv carbon / alloy steel (8.8, 10.9, 12.9) thiab stainless hlau A2-50 / A2-70 / A4-50 / A4-70. Cov txheej txheem saum npoo muaj xws li dub oxide, zinc plating, zinc-nickel, Dacromet thiab dawb. Ib nrab-xov thiab cov xov xov puv muaj nyob thoob qhov ntau thiab tsawg M1.6-M64.
Lub taub hau tuaj yeem nkag mus rau hauv qhov counterbore qhov dej ntws, txuag chaw. Dav siv nyob rau hauv machinery, moulds, automation, automotive thiab hluav taws xob sib dhos yuav tsum muaj siab clamping quab yuam thiab compact layout.
Ntsiab Specifications
Txheem: GB / T 70.1-2008, ISO 4762, sib hloov nrog DIN 912
Khoom Qib: A
Xov: Metric coarse xov
Qhov Loj: M1.6 ~ M64
Xov Hom: Full-thread / Partial-thread
Kev siv ceev faj
Kev sib tw cuab yeej yuav tsum tau
Siv tus yuam sij Allen qhov loj me rau kev teeb tsa. Tsis txhob hnav lossis tsis sib haum, uas tuaj yeem ua rau sab hauv hex lub qhov (socket stripping) thiab fastener tsis ua haujlwm
Tswj Tightening Torque
Ua raws li tus qauv torque qhov tseem ceeb rau cov qib sib xws. Over-torquing ua rau xov puas los yog lub taub hau puas; torque tsis txaus ua rau xoob kev sib txuas.
Counterbore Qhov Dimension
Xyuas kom counterbore qhov tob thiab txoj kab uas hla phim lub taub hau taub hau loj. Lub qhov (socket head) yuav tsum zaum tag nrho hauv lub txee; zam lub taub hau extrusion los yog lub rooj zaum tsis tiav.
Khoom siv & Environment Compatibility
Xaiv cov khoom tsim nyog thiab kho qhov chaw raws li kev ua haujlwm. Siv lub zog siab alloy steel rau kev siv hnyav-load; xaiv rau cov hlau tsis muaj steel lossis cov tshuaj tiv thaiv corrosion rau qhov chaw ntub lossis corrosive ib puag ncig.
Muag & Logistics
Kev lag luam: NA, EU, Asia Middle East
Ntim: hnab me me, cartons, pallets; customized ntim muaj.
Quality Assurance
Tau ntawv pov thawj rau ISO9001: 2015; IATF 16949 API-20E tag nrho cov khoom tau dhau qhov kev ntsuas qhov ntev thiab cov tshuab ua haujlwm.
Muab lub sijhawm ntev - lav zoo thiab kev ua haujlwm tom qab- kev muag khoom.
Kev siv tseem ceeb
General machinery, pwm, automation khoom, automotive qhov chaw, electronics, robotics, thiab dav kev lag luam sib dhos uas siab clamping quab yuam thiab compact installation yuav tsum tau.
Core Differences vs. Hexagon Head Bolts
| Yam khoom | Hexagon Socket Head Cap Screws (GB/T 70.1-2008) | Hexagon taub hau Bolts (egGB / T 5782 / DIN931) |
|---|---|---|
| Tsav hom | Sab hauv hexagon (Allen key) | Sab nraud hexagon (spanner / wrench) |
| Lub taub hau zoo | Lub taub hau cylindrical, haum rau hauv lub qhov taub | Sab nraud hexagonal taub hau, nthuav tawm sab nraud workpiece |
| Qhov chaw nruab | Yuav tsum tau me me radial qhov chaw; tuaj yeem ua dej ntws yaug lossis hauv qab qhov chaw | Xav tau kev tshem tawm ib ncig ntawm lub taub hau rau kev sib hloov, tsis tuaj yeem tog hauv |
| Torque Capacity | High torque kis tau tus mob, anti-slip nyob rau hauv hnyav load | Nruab nrab-siab torque; txaus ntshai wrench slipping ntawm cov ces kaum |
| Qib khoom | Qib A (siab precision) | Qib A / B |
| Hom Lub Zog | Mus txog 12.9 high-strength steel, stainless A2-70 / A4-70 | Mus txog 12.9 steel, stainless hlau muaj |
| Xov Option | Full-xov & ib nrab xov | Ib nrab xov (GB / T5782) / Full-xov (GB / T5783) |
| Daim ntawv thov Scenario | Pwm, automation, compact assembly, confined-space installation | Cov tshuab dav dav, cov qauv kev sib txuas, yooj yim nkag mus rau sab nraud txoj haujlwm |
| Qhov tsis zoo | Yooj yim rau strip puab hex yog tias over-torqued; xav tau Allen key | Loj installation hneev taw; tsis tuaj yeem raug countersunk |
Txij li thaum peb lub hauv paus hauv xyoo 2005, peb tau tsim cov kev txawj ntse ua haujlwm ntev li ob xyoos hauv kev lag luam fastener. Backed los ntawm tag nrho-automated kawg-rau-kawg tsim muaj peev xwm, peb ua tiav cov txiaj ntsig txhua xyoo ntawm ntau tshaj RMB 130 lab. Peb cov khoom lag luam nruab nrab-rau-high-end ua tiav pab cov neeg siv khoom thoob ntiaj teb.
