Professional Applications & Engineering Value
These M5 socket head cap screws deliver critical engineering solutions where space constraints and high-stress conditions coexist. The zinc-plated alloy steel construction provides essential corrosion protection while maintaining the Class 12.9 strength rating needed for heavy machinery, automotive assemblies, and precision equipment. The 4mm hex drive enables secure tool engagement in confined spaces, while the coarse thread design (0.8mm pitch) ensures rapid installation and superior vibration resistance. With Rockwell C37 hardness and 170,000 psi tensile strength, these fasteners prevent thread stripping and head deformation under extreme loads, making them ideal for critical joints in manufacturing equipment, robotics, and structural frameworks where reliability is paramount.
Specification Summary & Compliance
Manufactured to precise DIN 912/ISO 4762 standards with Class 5g6g thread fit tolerance ensuring consistent performance. The metric M5 x 0.8mm coarse thread configuration provides optimal engagement characteristics, while the 25mm length with 22mm threaded portion offers versatile fastening options. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across industrial sectors.
