Professional Applications & Engineering Value

These Class 12.9 socket head cap screws deliver exceptional engineering value in demanding industrial applications where failure is not an option. The blue-dyed zinc-plated alloy steel construction provides superior corrosion protection while maintaining the high tensile strength required for heavy machinery, automotive assemblies, and precision equipment. The 4mm hex drive ensures positive torque transmission without cam-out, while the partial threading design optimizes clamping force distribution. Meeting DIN 912/ISO 4762 standards, these metric fasteners solve critical challenges in vibration-prone environments, offering reliable performance where standard fasteners would fail. The combination of Rockwell C37 hardness and precise M5 coarse threading makes them ideal for high-stress applications requiring repeated disassembly and reassembly.

Specification Summary & Compliance

Manufactured to exacting DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise engagement. The metric M5x0.8mm coarse thread configuration provides optimal performance in industrial applications. These screws maintain compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming their suitability for global manufacturing requirements. The 22mm minimum thread length and 90mm overall length provide consistent dimensional accuracy across production batches.
