Professional Applications & Engineering Value
This M3 metric screw with zinc-plated steel construction addresses critical challenges in industrial assembly where vibration loosening and corrosion compromise joint integrity. The integrated internal-tooth lock washer bites into mating surfaces, creating permanent resistance to rotational forces in machinery, automotive subassemblies, and electronic enclosures. Its coarse 0.5mm pitch threads with Class 6g fit provide rapid installation while maintaining precise tolerance control. The Phillips No. 1 drive enables efficient torque transfer without specialized tools, making it ideal for high-volume production lines. Fully threaded along its 6mm length, this pan head screw delivers maximum thread engagement for secure fastening in sheet metal, plastic components, and light structural applications.
Specification Summary & Compliance
This fastener features M3 x 0.5mm coarse pitch threads with Class 6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The zinc-plated steel construction provides corrosion resistance while maintaining mechanical strength. Manufacturing complies with ISO 7045 specifications for pan head screws with washers. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, confirming the absence of restricted substances for industrial applications.
