• Superior hardness rating of Rockwell C37 provides excellent wear resistance and maintains thread integrity through repeated use
• Black-oxide coating on alloy steel offers enhanced corrosion protection for extended service life in demanding environments
• Precision hex socket drive with 2.5mm drive size allows for secure tool engagement and high torque application without stripping
• Class 5g6g thread fit ensures consistent mating with nuts and threaded holes for reliable assembly connections
• Full compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability in global applications
• RoHS 3 and REACH compliance meets environmental regulations for use in restricted substance-sensitive industries

Professional Applications & Engineering Value

This M3 socket head cap screw delivers critical engineering solutions where space constraints and high strength requirements intersect. The black-oxide alloy steel construction combined with Class 12.9 strength rating makes it ideal for machinery, automotive components, and precision equipment requiring reliable fastening under vibration and heavy loads. The coarse thread spacing (0.5mm pitch) provides faster assembly and reduced cross-threading risks compared to fine-thread alternatives. The hex socket drive design allows for compact installation in confined spaces while maintaining high torque capability. These metric socket screws are particularly valuable in manufacturing environments where standardized DIN 912/ISO 4762 components are specified for quality assurance and global compatibility.

Specification Summary & Compliance

This precision fastener features M3 x 0.5mm coarse metric thread with Class 5g6g thread fit tolerance, 10mm length, and standard socket head profile per DIN 912/ISO 4762 specifications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications with strict substance restrictions. The fully threaded design provides consistent engagement throughout the fastener length for uniform load distribution.
