Professional Applications & Engineering Value
This M5 socket head cap screw is engineered to address critical challenges in industrial assembly, where vibration, heavy loads, and environmental factors can compromise joint integrity. The black-oxide alloy steel construction provides a protective barrier against rust and oxidation, making it suitable for automotive, machinery, and outdoor equipment applications. With its coarse thread pitch of 0.8mm and Class 5g6g thread fit, it resists loosening under dynamic stresses while allowing for rapid installation. The 30mm length and partially threaded design offer flexibility in securing components without over-engagement, reducing the risk of strip-out. By meeting DIN 912/ISO 4762 standards, it delivers precise dimensional consistency, ensuring reliable performance in high-precision engineering systems.
Specification Summary & Compliance
This screw features M5 x 0.8mm coarse metric threading with a Class 5g6g thread fit for precise tolerance control. It is manufactured in accordance with DIN 912/ISO 4762 specifications, ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible sourcing and usage in industrial markets.
