S-90265A398 M12 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and extended service life.
• Precise component alignment and pivot points enabled by the 16mm diameter shoulder with tight tolerances, reducing assembly errors.
• High-strength performance under load with a tensile strength of 70,000 PSI and a minimum shear strength of 45,000 PSI for demanding applications.
• Secure, high-torque installation using the 8mm hex socket drive, preventing cam-out and ensuring a reliable, flush fit.
• Enhanced grip for manual adjustments thanks to the knurled head texture, facilitating handling during assembly and maintenance.
• Guaranteed dimensional interchangeability and quality through compliance with the ISO 7379 international standard.
• Safe for regulated industries with RoHS 3 and REACH compliance, ensuring the absence of hazardous substances.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to solve critical alignment and rotational challenges in industrial applications. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and equipment exposed to moisture or chemicals. The 16mm shoulder diameter and 45mm shoulder length provide a precise unthreaded bearing surface, which acts as a pivot, spacer, or axle, reducing wear on mating parts and simplifying assembly. The coarse pitch thread (1.75mm) and Class 5g6g thread fit ensure quick assembly and reliable fastening in high-vibration environments. Combined with the hex socket drive, it allows for high torque application in confined spaces, enhancing operational efficiency and reducing downtime in production lines.

Specification Summary & Compliance
