S-90269A258 M6 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh or chemical environments.
• Precise component alignment and location thanks to the 8mm shoulder diameter with tight tolerance control.
• High mechanical strength and durability with a tensile strength of 70,000 psi and Rockwell B79 hardness.
• Secure, flush installation enabled by the standard socket head and 4mm hex drive, minimizing protrusion.
• Reliable fastening in coarse-thread applications with the M6x1mm thread and Class 5g6g fit for consistent performance.
• Enhanced grip during manual assembly from the knurled head texture.
• Guaranteed quality and material safety through compliance with ISO 7379, RoHS 3, and REACH standards.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and pivot point challenges in mechanical assemblies. The 316 Stainless Steel material offers exceptional resistance to corrosion and oxidation, making it a reliable choice for marine, chemical processing, and food-grade equipment. The integrated 13mm shoulder length acts as a precise spacer or shaft, preventing misalignment in rotating parts like gears, pulleys, and linkages. The M6x1mm coarse thread and socket head design facilitate quick, secure installation in tight spaces, reducing assembly time while maintaining high shear strength. This combination of a robust shoulder diameter and standardized thread ensures long-term operational stability in high-stress industrial applications.
