- High tensile strength of 40,000 psi ensures reliable load-bearing capacity in demanding industrial environments.
- Flanged button head design eliminates the need for separate washers, providing a wider bearing surface and streamlined assembly.
- Precise Class 6g thread fit guarantees consistent engagement and vibration resistance in metric assemblies.
- 3mm hex drive allows for secure tool engagement and efficient installation with standard hex keys.
- Full threading along the 20mm length enables maximum adjustability and holding power across the entire fastener.
- Compliance with RoHS 3 and REACH regulations ensures environmental safety and suitability for regulated industries.
Professional Applications & Engineering Value
Engineered for precision and endurance, this M5 metric screw with Class 6g threading and 6061 aluminum material addresses common industrial challenges such as component weight reduction and corrosion management. The flanged button head integrates a washer-like base, distributing clamp load effectively to prevent surface damage and loosening under vibration—critical in machinery, electronics, and automotive assemblies. Its coarse 0.8mm pitch and fully threaded design facilitate quick installation and robust fastening in aluminum or composite materials, while the hex drive ensures torque reliability. Ideal for applications requiring high-strength, lightweight fasteners with regulatory compliance, this screw minimizes maintenance and enhances assembly integrity.
Specification Summary & Compliance
This fastener adheres to metric thread standards with Class 6g tolerance for precise fit. Dimensions include M5 x 0.8mm thread, 20mm length, 19.1mm flange diameter, and 3mm hex drive. It meets RoHS 3 (2015/863/EU) with exemption 6(b)-II and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances for industrial use.
