S-94361A594 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional Durability: Crafted from alloy steel with a Rockwell C32 hardness and 140,000 psi tensile strength to withstand high-stress applications and prevent fastener failure.
• Superior Corrosion Resistance: The black oxide finish provides a protective layer, extending the screw's service life in demanding industrial environments.
• Precision Alignment & Pivot Function: The 6.5mm shoulder diameter with tight tolerances ensures exact component location, reducing wear and simplifying assembly.
• Secure & Easy Installation: The hex socket (3mm drive) and knurled head offer excellent grip for high-torque installation and prevent tool slippage.
• Reliable Thread Engagement: The Class 6g metric thread with a coarse 0.8mm pitch ensures consistent, secure fastening and resistance to loosening under vibration.
• Global Compliance & Safety: Manufactured to be RoHS 3 and REACH compliant, meeting international environmental and safety regulations for worry-free procurement.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot challenges in precision industrial applications. The alloy steel core and black oxide finish combat corrosion and wear, making it ideal for machinery, automotive assemblies, and jigs where exposure to oils and moisture is common. The precisely machined shoulder acts as a built-in spacer or bearing surface, eliminating the need for additional components and reducing assembly time. The hex socket drive and knurled head texture ensure secure tool engagement in confined spaces, preventing damage during high-torque fastening. This design directly addresses the engineering need for a robust, reliable, and easy-to-install metric shoulder screw that maintains dimensional stability under load.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional standards, featuring an M5x0.8mm Class 6g thread for a standard fit. The shoulder diameter is held to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length to 0 to 0.25 mm, ensuring high precision in assembly. The product is manufactured in full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial supply chains.
