Professional Applications & Engineering Value

This M2 low profile socket head cap screw delivers critical engineering advantages in compact assemblies where space optimization and reliability are paramount. The 18-8 stainless steel composition provides exceptional corrosion resistance, eliminating failure risks in humid or chemically aggressive environments. The metric coarse thread with Class 6g fit ensures rapid assembly while maintaining vibration resistance in machinery, electronics, and precision instruments. The reduced head height design solves clearance issues in confined spaces without compromising the 1.3mm hex drive functionality, preventing cam-out during torque application. These fully threaded fasteners distribute clamping forces evenly, making them ideal for securing sensitive components in automotive, aerospace, and medical equipment applications where reliability cannot be compromised.

Specification Summary & Compliance

This metric fastener features M2 x 0.4mm pitch coarse threads with Class 6g manufacturing tolerance per ISO metric standards. The 8mm length provides consistent engagement depth while the low profile socket head maintains a 3.8mm diameter and 1.35mm height. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
