S-90269A576 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Enhanced durability and wear resistance from the black oxide finish, providing added protection and a sleek, non-reflective appearance.
• Precise component alignment and pivot points thanks to the smooth, accurately machined shoulder with controlled diameter and length tolerances.
• High-strength performance under load with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for reliable fastening in demanding applications.
• Secure and reliable thread engagement ensured by the Class 5g6g thread fit, reducing the risk of loosening or cross-threading.
• Easy installation and removal using a standard 3 mm hex key, providing a flush, low-profile head design that saves space.
• 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 pivot challenges in precision assemblies. The 316 stainless steel material offers exceptional resistance to chemicals, saltwater, and high temperatures, making it perfect for marine equipment, chemical processing machinery, and food-grade applications. The black oxide finish not only enhances corrosion protection but also reduces light reflection, which is vital in optical and electronic enclosures. The precisely controlled shoulder diameter and length provide a stable bearing surface, eliminating the need for additional spacers or bushings and reducing assembly time and component count. With its coarse metric thread (M5 x 0.8mm) and hex socket drive, it ensures quick, tool-friendly installation in tight spaces, improving maintenance efficiency and equipment uptime.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M5 thread size, 0.8 mm pitch, and a Class 5g6g thread fit for consistent dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring precise fit in machined components. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances and suitable for industrial and export use.
