Professional Applications & Engineering Value

This M8 alloy steel set screw is engineered to solve critical challenges in industrial assembly, where vibration resistance and precise component positioning are paramount. The headless design with hex drive allows for flush installation in tight spaces, eliminating protrusions that could interfere with machinery operation. Its extended tip ensures positive engagement with shaft keyways or collars, preventing slippage under torque. Manufactured from alloy steel and hardened to Rockwell C45, it withstands repeated adjustments and high dynamic loads without deforming. The coarse metric thread (1.25mm pitch) provides rapid installation and superior holding power in metals and engineered plastics, making it ideal for power transmission systems, automated machinery, and precision equipment requiring reliable set screw performance per DIN 915 and ISO 4028 specifications.

Specification Summary & Compliance

This set screw features M8 x 1.25mm coarse metric threads with Class 6g tolerance for precise fit, a 40mm length, and an extended tip (4.3mm length, 5.5mm diameter) with manufacturing tolerances of -0.3mm to 0. It is manufactured to conform to DIN 915 and ISO 4028 standards and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
