- Vibration-resistant performance with permanent nylon patch thread locking that maintains integrity from -70° to 250°F
- Exceptional corrosion resistance thanks to 18-8 stainless steel construction and passivated finish for harsh industrial environments
- Precise alignment and reduced wear with Class 6g thread fit and controlled shoulder diameter tolerance for stable component mounting
- High-strength durability offering 70,000 psi tensile strength and Rockwell B55 hardness for demanding mechanical applications
- Secure hex socket drive enabling high torque application without slippage and smooth head profile for clean installations
- Reliable regulatory compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
- Optimized for coarse threading with M8x1.25mm metric thread for quicker assembly and reduced cross-threading risks
Professional Applications & Engineering Value
This precision shoulder screw delivers critical engineering solutions where component alignment and vibration resistance are paramount. The 16mm shoulder length with precise tolerance control acts as a permanent dowel, eliminating bushing needs in machinery, automotive, and automation systems. Manufactured from 18-8 stainless steel with passivated finish, it withstands corrosive environments while the permanent nylon patch locking technology secures assemblies under thermal cycling from -70° to 250°F. The hex socket head ensures reliable torque transmission in space-constrained applications, making it ideal for high-tensile industrial fastening where loosening under dynamic loads would cause operational failure.
Specification Summary & Compliance
Manufactured to metric system standards with M8 coarse thread (1.25mm pitch) and Class 6g thread fit for precision engagement. Shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm ensure consistent precise fit. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety. Mechanical properties include 70,000 psi tensile strength and Rockwell B55 hardness for reliable performance in engineered assemblies.
