Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and mounting challenges in precision assemblies. The 316 stainless steel material offers exceptional resistance to corrosion and oxidation, making it suitable for medical devices, marine equipment, and food processing machinery where hygiene and durability are paramount. The 15mm shoulder length provides a stable bearing surface for rotating parts like gears and pulleys, reducing wear and maintaining precise clearances. Combined with the black oxide finish, it minimizes friction and galling during installation. The hex drive and knurled head ensure secure torque application, preventing slippage in high-vibration environments. Ideal for industrial fasteners in automation and electronics, this screw delivers reliable performance where metric thread accuracy and component longevity are essential.
