• Space-saving headless design allowing flush mounting in confined spaces where protruding fasteners aren't feasible

Professional Applications & Engineering Value

This M2.5 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel construction with Rockwell C45 hardness provides exceptional shear strength, preventing deformation under high torque loads in precision machinery, automotive components, and electronic enclosures. The cup point design creates permanent indentations in shaft surfaces, eliminating rotational slippage in power transmission systems. The hex drive style ensures maximum torque transfer during installation, while the coarse thread spacing enables rapid assembly in production environments. Meeting DIN 916/ISO 4029 standards, this metric set screw offers reliable performance in international manufacturing applications requiring consistent dimensional accuracy and mechanical properties.

Specification Summary & Compliance

This M2.5 x 0.45mm pitch set screw features precise Class 5g6g thread fit tolerances according to ISO metric standards, ensuring proper engagement in threaded holes. The 3mm length provides optimal grip depth for secure fastening in compact assemblies. Manufacturing compliance includes DIN 916 ISO 4029 specifications for dimensional accuracy and mechanical properties. Environmental compliance is verified through RoHS 3 (2015/863/EU) Compliant status for hazardous substance restriction and REACH (EC 1907/2006) Compliant certification for chemical safety regulations.
