Professional Applications & Engineering Value
This M3 socket head cap screw is engineered to address common industrial challenges such as space constraints and the need for high-strength, reliable fastening. The ultra-low profile head and fully threaded design with a coarse 0.5mm pitch enable quick assembly and secure holding power in machinery, automotive components, and electronic enclosures. Made from black-oxide alloy steel, it resists corrosion and wear, extending service life in harsh environments. The Class 5g6g thread fit ensures precise alignment and reduces the risk of cross-threading, making it ideal for repetitive or high-vibration applications where consistency is critical.
Specification Summary & Compliance
This screw features a metric M3 x 0.5mm coarse thread with Class 5g6g tolerance and a length of 25mm (±0.127mm tolerance). It is manufactured from alloy steel with a black-oxide surface treatment and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to international standards for industrial use.
