S-90269A465 M3 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for chemical, marine, and outdoor applications.
• Precise component alignment and pivot points enabled by the 25mm shoulder with controlled diameter tolerance, reducing wear and simplifying assembly.
• High mechanical strength and durability with a tensile strength of 70,000 psi and shear strength of 35,000 psi for reliable performance under load.
• Secure, non-slip installation with a knurled socket head and 2 mm hex drive, allowing for high torque application without tool slippage.
• Excellent thread engagement and consistency with a Class 5g6g thread fit and M3 x 0.5mm coarse pitch, ensuring vibration resistance and easy assembly.
• Enhanced wear resistance and minimal light reflection from the black oxide finish, providing a sleek look and added protection.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and export markets.

Professional Applications & Engineering Value

This M3 shoulder screw is engineered to address critical challenges in precision assembly and motion control systems. The 316 stainless steel material offers exceptional resistance to chemicals, saltwater, and extreme temperatures, preventing failure in demanding conditions like marine equipment or chemical processing machinery. The 25mm shoulder length acts as a precise spacer or bearing surface, eliminating the need for additional bushings and reducing assembly complexity in industrial automation, robotics, and conveyor systems. The black oxide finish not only enhances corrosion protection but also reduces galling and friction. Combined with the knurled socket head and hex drive, it ensures secure fastening in high-vibration environments, making it a reliable choice for OEMs and maintenance teams seeking durability and precision in metric fastener applications.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric thread standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for precise dimensional control. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted substances and suitable for global industrial and electronic applications.
