S-92981A206 M6 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional Durability: Crafted from high-strength alloy steel with a Rockwell C32 hardness, ensuring long-lasting performance and resistance to wear in demanding industrial environments.
• Superior Corrosion Resistance: The black oxide finish provides a protective layer, significantly enhancing the screw's resistance to rust and corrosion, extending its service life.
li>Precise Alignment & Pivot Function: The 40mm shoulder with controlled tolerances acts as a precise bearing surface or pivot point, reducing wear on mating parts and simplifying assembly.
• High Tensile & Shear Strength: With a tensile strength of 140,000 psi and a minimum shear strength of 84,000 psi, this screw reliably handles high-stress applications without failure.
• Secure and Easy Installation: The knurled socket head with a 4mm hex drive offers excellent grip, preventing cam-out and allowing for high torque application with standard tools.
• Guanteed Dimensional Accuracy: The Class 5g6g thread fit and precise shoulder diameter/length tolerances ensure consistent, reliable performance and easy assembly every time.
• Global Compliance & Safety: Meets ISO 7379 specifications and is compliant with RoHS 3 and REACH environmental standards, ensuring safety and suitability for international markets.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and pivot challenges in industrial applications. The alloy steel construction and black oxide finish provide the necessary strength and corrosion resistance for machinery, automotive assemblies, and precision instruments. The integral 40mm shoulder serves as a precise datum for locating parts, eliminating the need for and cost of separate spacers or bushings. This design minimizes assembly time, reduces component count, and prevents galling between moving parts. The coarse M6x1mm thread and Class 5g6g fit ensure rapid, secure fastening even in vibratory environments, making it an indispensable component for engineers seeking reliability and efficiency.
