Easy installation and removal with a standard No. 2 Phillips drive and fully threaded design for quick assembly.
Precise metric threading (M5 x 0.8mm, Class 6g) guarantees secure fits and interchangeability in global projects.
Durable Rockwell B70 hardness maintains screw integrity and resists wear over extended use.
Compliance with ASME B18.13.1M and environmental regulations ensures quality and safety for regulated industries.

Professional Applications & Engineering Value

This M5 pan head screw is engineered to address common industrial challenges such as vibration-induced failure and corrosion. The 18-8 stainless steel material combined with a passivated finish provides excellent resistance to rust and chemicals, making it suitable for outdoor machinery, automotive assemblies, and food processing equipment. The integrated external-tooth lock washer bites into surfaces to maintain clamp load, effectively resisting loosening in high-vibration environments like engines or conveyor systems. Its fully threaded coarse pitch design ensures rapid installation and strong holding power, while the Phillips drive allows for efficient torque application without specialized tools. Ideal for industrial fastening where reliability and regulatory compliance are critical.

Specification Summary & Compliance

This screw features M5 x 0.8 mm coarse threads with a Class 6g tolerance for precise fit, and is fully threaded for consistent performance. It meets ASME B18.13.1M specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial applications.
