Professional Applications & Engineering Value
These Class 12.9 socket head cap screws deliver critical performance where failure is not an option. The zinc-plated alloy steel construction provides excellent corrosion protection while maintaining 170,000 psi tensile strength - making them ideal for heavy machinery, automotive assemblies, and industrial equipment subjected to dynamic loads and vibration. The M12 x 1.75mm coarse thread with Class 5g6g fit ensures rapid installation and reliable seating in demanding production environments. The partially threaded design concentrates clamping force precisely where needed, preventing joint loosening in high-vibration applications while the 10mm hex drive accommodates standard tools for efficient maintenance and assembly operations.
Specification Summary & Compliance
Manufactured to DIN 912 / ISO 4762 specifications with Class 5g6g thread tolerance ensuring dimensional accuracy and interchangeability. These socket head cap screws feature M12 x 1.75mm coarse threads, 40mm length with 36mm minimum thread length, and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe industrial use worldwide.
