Professional Applications & Engineering Value

This M3 set screw is engineered to solve critical fastening challenges in precision assemblies. The alloy steel material, hardened to Rockwell C45, provides excellent shear and tensile strength, preventing failure under high-stress conditions. The 120° cone point and coarse thread work synergistically to create a powerful grip, making it ideal for securing collars, gears, and pulleys on shafts in machinery and automotive systems. Its headless design and hex drive allow for flush mounting and easy access in confined spaces, reducing assembly time and improving the aesthetic finish of the final product. By meeting DIN 914/ISO 4027 standards, it ensures reliability in industrial set screw applications where precision and consistency are non-negotiable.
