Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address critical alignment and pivot point requirements in precision assemblies. The 70mm shoulder length acts as a precise spacer or axle, eliminating the need for additional bushings and reducing assembly complexity. Manufactured from 316 Stainless Steel, it offers excellent corrosion resistance, making it suitable for applications in chemical processing, marine environments, and food machinery where exposure to moisture and corrosive agents is a concern. The combination of a hex socket drive and knurled head ensures high torque transmission and secure handling, preventing damage during installation. This industrial-grade fastener is ideal for securing rotating parts in machinery, guiding linear motion systems, and providing reliable joints in high-tensile applications, thereby enhancing overall equipment reliability and reducing maintenance downtime.
