S-96654A151 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking thanks to the integrated nylon patch, preventing loosening under dynamic loads and reducing maintenance needs.
• Exceptional corrosion resistance from 18-8 stainless steel and passivated finish, ensuring longevity in harsh industrial environments.
• High-strength performance with 70,000 psi tensile strength and Rockwell B55 hardness for reliable, heavy-duty fastening.
• Precise alignment and spacing enabled by the 8mm shoulder with tight diameter tolerance (-0.025 to 0mm), minimizing part movement.
• Secure hex socket drive allows for high-torque installation with a standard 4mm hex key, reducing strip-out risks.
• Wide temperature tolerance from -70° to 250°F, maintaining integrity in varied operational conditions.
• Regulatory compliance with RoHS 3 and REACH, ensuring safety and environmental standards are met for global supply chains.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical challenges in precision assemblies where alignment and vibration resistance are paramount. The 8mm shoulder with precise tolerances acts as a built-in spacer, eliminating the need for additional components and reducing assembly errors in machinery, automation systems, and rotating equipment. Made from 18-8 stainless steel with a passivated finish, it resists oxidation and chemical exposure, extending service life in demanding environments. The integrated nylon patch locking feature secures the Class 6g metric thread against vibration-induced loosening, making it ideal for applications in automotive, aerospace, and industrial robotics. Its hex socket head design ensures easy installation in confined spaces, enhancing efficiency while maintaining high tensile strength for reliable performance.

Specification Summary & Compliance

This shoulder screw adheres to metric thread standards with M6x1mm coarse pitch and Class 6g thread fit for consistent engagement. The shoulder features precise dimensions: diameter tolerance of -0.025 to 0mm and length tolerance of 0 to 0.05mm, ensuring accurate fit in assemblies. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and industrial safety requirements.
