• Superior corrosion resistance provided by blue-dyed zinc plating, extending service life in harsh industrial environments
• Precision thread engagement with Class 5g6g fit and 0.5mm coarse pitch for faster assembly and reduced cross-threading risk
• Optimized drive efficiency featuring 2.5mm hex socket for secure tool engagement and high torque transmission without slippage
• Versatile partial threading with 18mm thread length allowing unthreaded shank sections for precise component alignment
• Global standard compliance meeting DIN 912/ISO 4762 specifications for international project compatibility
• Enhanced durability with Rockwell C37 hardness maintaining structural integrity under repeated loading cycles

Professional Applications & Engineering Value

These M3 socket head cap screws deliver critical engineering solutions where space constraints and high-stress conditions coexist. The blue-dyed zinc-plated alloy steel construction provides both corrosion protection and visual identification advantages in complex assemblies. With Class 12.9 strength rating and 170,000 PSI tensile strength, they prevent joint failure in machinery, automotive systems, and precision equipment. The partially threaded design with 18mm thread length ensures secure fastening while allowing smooth alignment through unthreaded sections. The 2.5mm hex drive accommodates standard tools for efficient maintenance in confined spaces, while the coarse pitch metric thread (0.5mm) resists vibration-induced loosening in dynamic applications.

Specification Summary & Compliance

Manufactured to DIN 912/ISO 4762 standards with Class 5g6g thread fit ensuring dimensional accuracy and interchangeability. The screws feature right-hand coarse threads (0.5mm pitch) and 18mm minimum thread length on a 30mm overall partially threaded body. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across industrial sectors.
