Professional Applications & Engineering Value
These high-strength socket head cap screws deliver critical performance advantages in heavy-duty industrial applications where failure is not an option. The zinc-plated alloy steel construction provides essential corrosion protection for machinery operating in demanding environments, while the Class 12.9 rating ensures reliable performance under extreme vibrational loads and tension requirements. The partially threaded M5 design with coarse 0.8mm pitch offers superior clamping force distribution, making these metric screws ideal for precision equipment, automotive assemblies, and industrial machinery where hex drive accessibility and high torque application are essential. The combination of 170,000 psi tensile strength and controlled Rockwell C37 hardness prevents thread deformation and maintains fastener integrity through repeated disassembly cycles.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise engagement. The M5 x 0.8mm coarse thread configuration provides optimal performance in standard applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming these fasteners meet the latest international environmental and safety standards for industrial components.
