S-90269A137 M5 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 enabled by the 6mm shoulder diameter with a tight tolerance of -0.072 to -0.01 mm.
• High mechanical strength with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for reliable, durable assemblies.
• Secure and efficient installation using the standard 3 mm hex socket drive, preventing cam-out and enabling high torque application.
• Consistent and reliable thread engagement ensured by the Class 5g6g thread fit and M5x0.8 coarse pitch for faster assembly.
• Enhanced durability from a Rockwell B79 hardness, providing excellent wear resistance in dynamic applications.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global markets.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and wear challenges in industrial assemblies. The precision-machined 6mm shoulder acts as a pivot, bearing surface, or locator, eliminating the need for and cost of additional spacers or bushings. Manufactured from 316 Stainless Steel, it offers exceptional resistance to corrosion from chemicals, saltwater, and extreme temperatures, making it a top choice for marine equipment, food processing machinery, and chemical processing applications. The Class 5g6g thread fit and coarse 0.8mm pitch ensure vibration resistance and quick installation, while the hex socket head provides a flush profile and secure drive in confined spaces. This combination of precision, material integrity, and design directly enhances assembly longevity and reduces maintenance cycles.

Specification Summary & Compliance
