Professional Applications & Engineering Value

This M24 set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The alloy steel construction with Rockwell C45 hardness provides exceptional shear strength and wear resistance, preventing deformation under high torque applications. The cup point design bites securely into mating surfaces, creating permanent alignment in machinery shafts, gears, and pulleys where rotational forces would otherwise cause component slippage. Manufactured to DIN 916/ISO 4029 standards with metric coarse threads, this headless screw offers reliable performance in industrial equipment, automotive assemblies, and heavy machinery where space constraints and vibration are constant challenges. The 12mm hex drive ensures sufficient torque application without stripping, while the right-hand thread configuration maintains compatibility with standard installation practices.

Specification Summary & Compliance

This metric set screw features M24x3mm coarse threads with Class 5g6g thread fit ensuring precise dimensional accuracy according to ISO standards. The manufacturing process adheres to DIN 916 ISO 4029 specifications for dimensional consistency and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for use across various industrial sectors without environmental concerns.
