S-92981A756 M8 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 140,000 psi tensile strength and 84,000 psi minimum shear strength for reliable performance in demanding applications.
• Superior wear and corrosion resistance thanks to the black oxide finish on the alloy steel, extending service life in harsh industrial environments.
• Precise alignment and component location enabled by the 10mm shoulder diameter with tight tolerance, reducing assembly errors and improving product quality.
• High-strength, durable core material with Rockwell C32 hardness, ensuring the screw maintains its integrity under repeated stress and vibration.
• Easy and secure installation with a 5mm hex socket drive, allowing for high torque application and reducing the risk of tool slippage.
• Guaranteed dimensional consistency and interchangeability through compliance with ISO 7379 standards and Class 5g6g thread fit.
• Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to solve critical alignment and durability challenges in precision assemblies. The alloy steel construction, combined with a black oxide finish, provides excellent resistance to corrosion and wear, making it ideal for machinery, automotive, and automation equipment where exposure to oils and moisture is common. The 10mm shoulder diameter acts as a precise pivot or bearing surface, ensuring components like gears and pulleys are accurately positioned, which minimizes wear and prevents misalignment. The coarse metric thread (M8x1.25) and right-hand thread direction facilitate quick installation in metals and plastics, while the socket head design allows for compact spaces and high clamping force. By integrating these features, this screw reduces maintenance needs and enhances the longevity and reliability of your industrial fastening systems.
