Professional Applications & Engineering Value

This M4 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial machinery. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for washdown environments, food processing equipment, and outdoor applications. The precision-machined 10mm shoulder acts as a built-in spacer or bearing surface, eliminating the need for separate bushings and ensuring exact component positioning in assemblies like linkages, gears, and pulleys. The coarse thread (M4x0.7) and hex socket head allow for quick, secure fastening even in confined spaces, reducing assembly time and preventing loosening under dynamic loads. Its high Rockwell B83 hardness and strength ensure long-term reliability in high-cycle applications, from automotive jigs to conveyor systems.

Specification Summary & Compliance
