S-90269A634 M6 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments and chemical exposure.
• Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing in demanding applications.
• Precise alignment and spacing enabled by the 8mm shoulder diameter with tight tolerances, reducing wear on mating components.
• Secure and tool-resistant fastening with a knurled, hex socket head design for improved grip and reduced cam-out during installation.
• Durable, wear-resistant surface thanks to the black oxide finish, which also provides a consistent, professional appearance.
• Broad industry compatibility ensured by compliance with ISO 7379, RoHS 3, and REACH standards for global engineering projects.
• Reliable thread engagement with a Class 5g6g thread fit and coarse M6x1mm thread for quick assembly and vibration resistance.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 316 Stainless Steel material provides excellent resistance to corrosion and oxidation, making it suitable for use in machinery, automotive assemblies, and marine equipment. The 12mm shoulder length and 8mm shoulder diameter with precise tolerances ensure accurate component positioning, reducing misalignment and extending the service life of moving parts. The black oxide finish not only enhances corrosion protection but also minimizes galling. Combined with a coarse thread pitch and hex socket drive, this screw offers efficient installation and high clamp load retention, ideal for precision engineering and high-vibration environments.

Specification Summary & Compliance
