Professional Applications & Engineering Value

This M4 socket head cap screw combines 18-8 stainless steel construction with advanced nylon patch thread locking technology to solve critical industrial fastening challenges. The hex drive socket head design enables high-torque installation in space-constrained applications while maintaining superior grip. Engineered for machinery, automotive, and precision equipment assemblies, the partially threaded configuration provides optimal stress distribution and prevents joint loosening under vibration. The 0.7mm coarse pitch metric thread ensures rapid installation and reliable performance in high-cycle manufacturing environments. With temperature resistance from -70° to 250°F for the locking element and -80° to 400°F for the silicone rubber O-ring, this fastener delivers consistent performance across extreme operating conditions in industrial automation, heavy equipment, and precision instrumentation applications.

Specification Summary & Compliance

This socket head cap screw features precise M4 x 0.7mm metric threading with Class 6g thread fit tolerance for optimal engagement. Manufactured to DIN 912/ISO 4762 standards, ensuring dimensional accuracy and interchangeability. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict regulatory adherence. The partially threaded design with 20mm minimum thread length provides engineering flexibility while maintaining structural integrity.
