• Optimized Drive Performance: The 1.5mm hex drive offers high torque transfer and reduces the risk of stripping for efficient assembly.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and space constraints in precision assemblies. The 10mm shoulder length with precise tolerances acts as a built-in dowel, ensuring accurate axial and radial positioning of components like gears, pulleys, and linkages, which eliminates the need for additional locating pins and reduces assembly complexity. Made from 18-8 stainless steel with a passivated finish, it provides excellent resistance to oxidation and chemical exposure, making it ideal for medical devices, electronics, and optical equipment where cleanliness and durability are paramount. The low-profile socket head design is crucial for applications with limited clearance, while the Class 6g thread fit and coarse thread spacing ensure quick and secure fastening, reducing installation time and improving overall mechanical reliability in automated and high-vibration environments.
