• Secure and reliable fastening with a standard hex socket head and 3/32" drive, providing a positive grip and reducing the risk of tool slippage.
• Broad temperature tolerance from -40° to 140° F, ensuring consistent performance in varied operating conditions.
• Precise Class 6g thread fit for smooth installation and reliable engagement in metric coarse-threaded applications.
• Fully threaded M3 x 0.5mm design offers maximum holding power and uniform load distribution along the entire 5mm length.
• Compliance with major safety and environmental standards including UL 94 V-2 flammability rating, RoHS 3, and REACH, ensuring product safety and regulatory acceptance.
• Lightweight and non-conductive properties make it perfect for applications where metal fasteners could cause interference or add unnecessary weight.

Professional Applications & Engineering Value

This M3 nylon socket head cap screw is engineered to address common challenges in industrial and electronic assemblies where corrosion resistance and electrical insulation are critical. The nylon plastic construction eliminates galvanic corrosion risks and provides a reliable, non-magnetic fastening solution. Its fully threaded metric design with a coarse 0.5mm pitch ensures quick installation and strong retention in plastics and soft materials, reducing the likelihood of stripping. The standard socket head with a 3/32" hex drive allows for high-torque application in confined spaces, making it ideal for electrical enclosures, consumer electronics, and light-duty machinery that require repeated disassembly without compromising thread integrity.

Specification Summary & Compliance

This screw features a metric M3 thread with a 0.5mm coarse pitch and Class 6g thread fit for standard tolerance. The dimensions include a head diameter of 4.6mm, head height of 2.8mm, and a length of 5mm. It is manufactured to meet UL 94 V-2 flammability specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances and suitable for global industrial use.
