• Secure, tamper-resistant installation via the hex socket head, allowing high torque application and access in confined spaces.
• Accurate shoulder diameter and length with tight tolerances for precise component alignment and rotational movement.
• Compliance with RoHS 3 and REACH ensures environmental safety and unrestricted use in regulated industries.
• Durable and long-lasting performance backed by Rockwell B79 hardness, resisting wear and deformation under load.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The M5x0.8 coarse thread and Class 5g6g thread fit provide quick, reliable assembly while minimizing thread damage. The 80mm shoulder length acts as a precise pivot or spacer in machinery, ensuring accurate alignment of moving parts like gears, bearings, and linkages. Its hex socket drive allows for secure tightening in tight spaces, reducing installation time and improving safety. Ideal for industrial automation, conveyor systems, and precision equipment, this fastener delivers consistent performance in demanding applications where reliability and corrosion resistance are critical.
