S-90269A730 M8 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction and black oxide finish, ideal for harsh industrial environments.
• Enhanced durability and load-bearing capacity from a high tensile strength of 70,000 psi and minimum shear strength of 35,000 psi.
• Precise component alignment and spacing enabled by the 10mm diameter shoulder with tight diameter tolerance (-0.072 to -0.01 mm).
• Secure, non-slip installation thanks to the knurled head texture and 5mm hex socket drive for reliable torque application.
• Wide compatibility and easy assembly with M8x1.25mm coarse metric threads and Class 5g6g thread fit for consistent performance.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety and regulatory adherence.
• Optimized for high-stress applications with a Rockwell B79 hardness and robust shoulder design for mechanical assemblies.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address common challenges in precision machinery, automation, and structural assemblies. The 316 Stainless Steel material, combined with a black oxide finish, provides exceptional resistance to corrosion, chemicals, and oxidation, making it suitable for demanding environments like marine, chemical processing, and outdoor equipment. The 10mm shoulder diameter with minimal tolerance ensures accurate positioning of components, reducing misalignment and wear in rotating parts or bearing mounts. The coarse thread pitch (1.25mm) and Class 5g6g thread fit facilitate quick, secure fastening in high-vibration settings, while the knurled head and hex socket drive enhance grip and torque efficiency during installation. Ideal for use in industrial machinery, automotive systems, and electronic enclosures, this screw delivers reliable performance, extended service life, and compliance with global standards like ISO 7379.
