Professional Applications & Engineering Value

This M4 set screw is engineered to address critical challenges in precision assembly and machinery. The alloy steel composition, hardened to Rockwell C45, provides the necessary strength to withstand high torsional and axial loads without stripping or shearing. Its headless design and 2mm hex drive make it ideal for applications where space is limited, such as in compact motor housings, gear assemblies, and precision instruments. The coarse metric thread with a 0.7mm pitch and Class 6g thread fit ensures quick, reliable fastening, reducing assembly time while maintaining tight tolerances. The serrations locking feature and cup tip work synergistically to prevent rotational movement and provide a firm grip, making these industrial set screws a trusted solution for securing collars, pulleys, and other components subject to dynamic forces.

Specification Summary & Compliance

This set screw adheres to ISO 4029 specifications, with a Class 6g thread fit ensuring dimensional accuracy for metric coarse threads.
