S-92981A109 M5 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with alloy steel construction, providing a tensile strength of 140,000 psi and shear strength of 84,000 psi for reliable performance in demanding applications.
• Superior corrosion resistance thanks to the black oxide finish, extending the screw's lifespan in harsh industrial environments.
• Precise alignment and smooth rotation enabled by the 60mm shoulder length with tight tolerances, reducing wear and ensuring consistent operation in assemblies.
• Easy installation and removal with a hex socket head and 3mm drive size, allowing for efficient assembly using standard tools.
• Accurate and secure fastening through the M5 coarse thread with Class 5g6g fit, minimizing the risk of cross-threading and ensuring stable connections.
• High hardness for wear resistance with Rockwell C32 rating, maintaining structural integrity under repeated stress and friction.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety and environmental responsibility for global supply chains.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered from alloy steel with a black oxide finish to address common industrial challenges like corrosion, misalignment, and mechanical failure. The 60mm shoulder length provides a precise bearing surface, ideal for applications in machinery, automotive systems, and precision instruments where components must rotate or pivot smoothly without loosening. The coarse thread and Class 5g6g fit ensure quick assembly and reliable holding power, reducing downtime in production lines. By combining high tensile and shear strength with consistent dimensions per ISO 7379, it delivers long-term reliability in heavy-duty environments, minimizing maintenance needs and enhancing operational efficiency for B2B clients.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm, with threads conforming to Class 5g6g fit for metric coarse applications. It meets ISO 7379 specifications for manufacturing consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use worldwide.
