Professional Applications & Engineering Value
This M4 socket head cap screw delivers exceptional engineering value across precision machinery, automotive assemblies, and industrial equipment. The 18-8 stainless steel composition provides excellent corrosion resistance in demanding environments, while the coarse thread pitch (0.7mm) ensures rapid installation without cross-threading risks. The partially threaded configuration with 20mm of engaged threads creates optimal clamping force distribution, preventing joint loosening under vibration. With its 3mm hex drive and standardized socket head profile, this fastener enables high-torque applications in confined spaces where wrench clearance is limited, making it ideal for precision engineering applications requiring reliable, maintenance-free performance.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 specifications with Class 6g thread fit tolerance for precise metric threading. Features M4 x 0.7mm coarse threads, 80mm overall length with 20mm threaded portion, and standard socket head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications without hazardous substance restrictions.
