Professional Applications & Engineering Value

This M8 set screw is engineered to solve critical challenges in precision machinery and assembly. The alloy steel material, combined with Rockwell C45 hardness, provides the necessary strength to resist shear forces and repeated adjustments without deforming. The fine metric thread (1mm pitch) and Class 5g6g thread fit ensure a tight, secure fit that minimizes backlash and maintains alignment in pulleys, gears, and collars. The cup point concentrates pressure to create a permanent dimple in the shaft, offering superior resistance to loosening compared to other tip styles. This makes it an indispensable hex headless screw for high-precision applications in automotive, aerospace, and industrial equipment manufacturing, where reliability is non-negotiable.

Specification Summary & Compliance

This set screw conforms to the dimensional and tolerance requirements of DIN 916 / ISO 4029. The Metric M8 x 1mm fine thread is manufactured to a Class 5g6g thread fit, ensuring high precision. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
