S-92981A535 M12 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced Durability: Alloy steel construction with Rockwell C32 hardness ensures long-lasting performance in demanding industrial environments.
• Superior Corrosion Resistance: Black oxide finish provides reliable protection against rust, extending service life and reducing maintenance needs.
• Precision Alignment: 16mm shoulder diameter with tight tolerance (-0.072 to -0.01 mm) ensures accurate component positioning and reduces assembly errors.
• High Load Capacity: 140,000 psi tensile strength and 84,000 psi minimum shear strength support heavy-duty applications without failure.
• Secure Fastening: Class 5g6g thread fit and coarse 1.75mm pitch enable quick, stable installation with reduced risk of stripping.
• Efficient Installation: 8mm hex socket drive allows for high-torque application with standard tools, speeding up assembly processes.
• Regulatory Compliance: Meets ISO 7379, RoHS 3, and REACH standards, ensuring safety and environmental responsibility in global markets.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and strength requirements in precision machinery. The alloy steel core, combined with a black oxide finish, resists wear and corrosion in harsh conditions like automotive assemblies or industrial robots. The 45mm shoulder length with minimal tolerance provides a stable pivot or spacer, minimizing misalignment in rotating parts. Its metric coarse thread (1.75mm pitch) and Class 5g6g fit ensure reliable engagement in high-vibration settings, reducing loosening risks. Ideal for applications requiring exact positioning—such as conveyor systems or CNC equipment—this screw enhances operational reliability while complying with ISO 7379 for consistent quality.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit for precise metric threading. Dimensions include a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm, ensuring accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material integrity for industrial use.
