Professional Applications & Engineering Value

This alloy steel set screw is engineered to solve critical fastening challenges in industrial assemblies. The M8 coarse thread with Class 5g6g tolerance provides excellent resistance to loosening under vibration, making it ideal for machinery, automotive components, and precision equipment. The 90° cone point creates concentrated pressure for superior grip on shafts and collars, preventing slippage in high-torque applications. Manufactured from alloy steel and hardened to Rockwell C45, it maintains integrity under repeated adjustments. The headless design with 4mm hex drive allows installation in tight spaces where conventional fasteners can't fit, while maintaining full DIN 914/ISO 4027 compliance for reliable performance across European and international projects.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse threads with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. The 16mm length and 90° cone point provide consistent penetration depth and holding force. Manufacturing specifications strictly adhere to DIN 914 ISO 4027 for dimensional and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no substances of very high concern (SVHC) as of the current declaration.
