S-90265A294 M8 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments.
• Precise component alignment and reduced wear thanks to the 15mm shoulder with controlled diameter and length tolerances.
• High-strength fastening with a tensile strength of 70,000 psi and a minimum shear strength of 45,000 psi for reliable performance.
• Secure, high-torque installation enabled by the 5mm hex socket drive and knurled head for improved grip.
• Accurate and reliable thread engagement ensured by the Class 5g6g thread fit and M8 x 1.25mm coarse thread profile.
• Global compliance and quality assurance through ISO 7379 certification and adherence to RoHS 3 & REACH regulations.
• Enhanced durability from a Rockwell B83 hardness rating, providing excellent resistance to deformation.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial applications. The precision-machined 15mm shoulder acts as a built-in spacer, eliminating the need for additional bushings and reducing assembly complexity. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it suitable for machinery, automation systems, and equipment exposed to moisture or chemicals. The hex socket head with a knurled texture allows for high-torque installation in confined spaces, while the coarse thread (1.25mm pitch) ensures rapid assembly and robust holding power. Its compliance with ISO 7379 guarantees dimensional consistency and interchangeability, providing engineers with a reliable component for high-precision mechanisms.
