Professional Applications & Engineering Value

This alloy steel set screw delivers exceptional engineering value in applications requiring permanent positioning of components on shafts, axles, and within assemblies. The M5 metric thread with coarse 0.8mm pitch provides rapid installation while the 90° cone point creates concentrated pressure points that prevent slippage under vibration and rotational forces. Manufactured to DIN 914 and ISO 4027 standards, this headless set screw ensures dimensional consistency and interchangeability across global engineering projects. The Rockwell C45 hardness maintains point integrity through repeated adjustment cycles, making it ideal for precision machinery, automotive components, and industrial equipment where reliable positioning is critical to system performance.

Specification Summary & Compliance

This precision fastener features Class 5g6g thread fit tolerance per metric standards, ensuring consistent engagement across mating components. The M5 x 0.8mm coarse thread configuration follows established metric threading specifications with right-hand direction for standard applications. Manufacturing and quality control adhere to DIN 914 ISO 4027 specifications, guaranteeing dimensional accuracy and performance reliability. Environmental compliance is verified through RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current substance restrictions, making this set screw suitable for regulated industries and international markets.
