S-92981A595 M16 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced Durability & Corrosion Resistance – Black oxide finish protects against rust and wear, extending service life in harsh industrial environments.
• Superior Tensile & Shear Strength – Alloy steel construction with 140,000 psi tensile strength and 84,000 psi minimum shear strength ensures reliable performance under high-stress conditions.
• Precision Fit & Alignment – Class 4g6g thread fit and controlled shoulder diameter tolerance (-0.072 to -0.01 mm) provide accurate positioning and reduced assembly play.
• Efficient Hex Drive Installation – 10 mm hex socket drive allows for high-torque application with standard tools, speeding up assembly and maintenance.
• Consistent Mechanical Properties – Rockwell C32 hardness offers a balance of toughness and machinability, reducing the risk of stripping or deformation.
• Broad Regulatory Compliance – Meets ISO 7379 standards and is RoHS 3 and REACH compliant, ensuring safe use in regulated industries.
• Optimized Shoulder Design – 20 mm shoulder diameter and 30 mm shoulder length provide stable bearing surfaces for pivoting or spacing components.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision assemblies. The alloy steel core, combined with a black oxide finish, resists corrosion while maintaining high tensile strength for demanding applications such as machinery linkages, robotic arms, and conveyor systems. The coarse metric thread (M16x2mm) and hex socket drive enable quick, secure fastening, reducing installation time and minimizing the risk of cross-threading. With a smooth shoulder and tight tolerances, it ensures precise component spacing and rotational stability, making it ideal for use in automotive jigs, packaging equipment, and industrial automation where repeatability and durability are paramount.

Specification Summary & Compliance
