Professional Applications & Engineering Value
This M5 brass rounded head screw delivers exceptional performance in industrial applications where corrosion resistance and electrical conductivity are critical. The metric coarse thread (0.8mm pitch) with Class 6g tolerance ensures reliable mating with corresponding nuts and tapped holes, while the fully threaded design maximizes holding power in thin materials. The combination of brass material and hex drive configuration makes it ideal for electrical enclosures, marine equipment, and plumbing systems where galvanic corrosion must be prevented. The rounded button head profile provides a finished appearance while the 3mm hex drive allows for high-torque installation without damaging the fastener head.
Specification Summary & Compliance
This metric fastener features M5 x 0.8mm coarse threads with Class 6g thread fit per ISO standards, ensuring precise dimensional accuracy. The 20mm fully threaded length and 9.5mm head diameter provide consistent performance across applications. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) compliance, meeting international environmental and safety regulations for industrial components.
