S-90269A454 M2 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life
• Enhanced durability and wear resistance from the black oxide finish, providing added protection and a sleek, non-reflective appearance
• Precise component alignment and smooth rotation ensured by the 12mm shoulder with controlled diameter and length tolerances
• High-strength fastening performance with a tensile strength of 70,000 psi and a shear strength of 35,000 psi for reliable load-bearing applications
• Secure, slip-resistant installation using a standard hex socket (2mm drive) and a knurled head for improved grip during tightening
• Accurate and consistent thread engagement with a Class 5g6g metric thread fit, reducing the risk of cross-threading and assembly issues
• Compliance with international environmental and safety standards including RoHS 3 and REACH, ensuring suitability for regulated industries

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and pivot point requirements in precision assemblies. The 316 stainless steel material offers exceptional resistance to chemicals, saltwater, and industrial atmospheres, making it perfect for marine, chemical processing, and food-grade equipment. The 12mm shoulder length provides a precise bearing surface for moving parts like gears, linkages, and rollers, minimizing wear and maintaining operational accuracy. The black oxide finish not only enhances corrosion protection but also reduces light reflection in sensitive optical or electronic devices. With its hex socket drive and knurled head, it allows for high-torque installation in confined spaces, ensuring reliable performance in automated machinery, medical devices, and precision instruments where metric coarse threading (M2 x 0.4mm) and consistent fit are paramount.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring precise thread engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, guaranteeing high dimensional accuracy for reliable assembly. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of restricted hazardous substances and suitable for global industrial applications.
