Professional Applications & Engineering Value

This M5 set screw delivers exceptional engineering value in applications requiring secure component positioning and torque transmission. The alloy steel construction with Rockwell C45 hardness provides the necessary strength to withstand vibrational forces and mechanical stress in machinery, automotive assemblies, and precision equipment. The cup point design creates concentrated pressure that digs into shaft surfaces, preventing rotational slippage in pulleys, gears, and collars. The metric coarse thread (M5x0.8mm) with Class 5g6g fit ensures quick assembly while maintaining precise tolerance control. The headless configuration and 2.5mm hex drive make it ideal for space-constrained applications where accessibility is limited, providing reliable fastening solutions for OEM manufacturers and maintenance professionals.

Specification Summary & Compliance

This set screw features precise M5x0.8mm metric coarse threads with Class 5g6g thread fit tolerance according to ISO standards, ensuring dimensional accuracy and proper engagement. Manufactured to meet DIN 916 and ISO 4029 specifications for quality and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use in various industrial sectors with strict chemical substance restrictions.
