Professional Applications & Engineering Value

This M8 set screw delivers exceptional engineering value in industrial applications where secure positioning is critical. The alloy steel construction with Rockwell C45 hardness ensures the fastener maintains its integrity under vibration and heavy loads, preventing premature failure in machinery components. The 120° cone point creates a definitive seating point that resists rotational forces, making it ideal for securing gears, pulleys, and collars on shafts. The headless design combined with metric coarse threading allows for flush mounting in confined spaces while providing rapid installation in production environments. These industrial set screws solve common engineering challenges of component slippage and maintenance accessibility across automotive, manufacturing, and heavy equipment applications.

Specification Summary & Compliance

This metric set screw features precise M8 x 1.25mm coarse threading with Class 5g6g thread fit tolerance per ISO standards, ensuring consistent performance across applications. Manufactured to DIN 914 and ISO 4027 specifications, the fastener maintains dimensional accuracy for reliable interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) environmental directives and REACH (EC 1907/2006) regulations, meeting the latest substance restriction requirements for industrial use across global markets.
