- Precise component alignment through controlled shoulder diameter (10mm) and length (8mm) with tight manufacturing tolerances
- Reliable performance under thermal stress with thread locker effectiveness maintained from -70° to 250° F
- High-strength fastening solution delivering 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications
- Secure installation and removal with standard hex socket drive (5mm) preventing tool slippage and damage
- Industry compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing requirements
Professional Applications & Engineering Value
This precision shoulder screw addresses critical engineering challenges in industrial assembly where vibration resistance and component alignment are paramount. The M8 metric thread with 1.25mm coarse pitch combined with Class 6g thread fit ensures reliable engagement in machinery, automotive, and precision equipment applications. The permanent nylon patch thread locker eliminates the need for secondary locking components while maintaining clamping force under extreme thermal cycling from -70° to 250° F. The 18-8 stainless steel material with passivated finish provides superior corrosion resistance in harsh environments, while the precise shoulder dimensions (10mm diameter, 8mm length) enable accurate component positioning in assemblies requiring exact axial alignment.
Specification Summary & Compliance
This metric shoulder screw features M8x1.25mm coarse threads with Class 6g thread fit tolerance and precise shoulder dimensions (10mm diameter with -0.025 to 0 mm tolerance, 8mm length with 0 to 0.05 mm tolerance). Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength, the fastener includes permanent nylon patch thread locking technology. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
