S-90269A683 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure.
• Exceptional mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance under high stress.
• Precise component alignment enabled by the 50mm shoulder with tight diameter tolerance for reduced wear and vibration.
• Secure and efficient installation with a 5mm hex drive and knurled head texture, preventing tool slippage.
• Robust thread engagement using Class 5g6g fit M6x1mm coarse threads for quick assembly and consistent clamping force.
• Long-term durability backed by Rockwell B79 hardness, resisting deformation in demanding applications.
• Global compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot point challenges in industrial machinery, automation systems, and precision instruments. The 316 Stainless Steel material provides excellent resistance to corrosion from chemicals, moisture, and salt spray, making it suitable for food processing, marine, and pharmaceutical equipment. The 50mm shoulder length acts as a precise axle or locating pin, minimizing radial play and bearing surface wear. Combined with the Class 5g6g thread fit and coarse 1mm pitch, it ensures rapid assembly and maintains clamping force in high-vibration environments. The knurled socket head with hex drive enhances torque transmission, reducing the risk of stripping during repeated maintenance cycles.

Specification Summary & Compliance
