Professional Applications & Engineering Value
This M4 socket head cap screw combines multiple engineering solutions for demanding industrial applications. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining Rockwell B85 hardness for durability in mechanical assemblies. The integrated nylon patch thread locking system prevents loosening under vibration, making it ideal for machinery, automotive components, and precision equipment. Combined with the Buna-N rubber O-ring seal, this fastener creates both mechanical security and environmental protection, resisting fluids and contaminants across wide temperature ranges. The partially threaded design with Class 6g thread fit ensures precise engagement while the metric coarse threading facilitates rapid assembly in production environments.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 standards with Class 6g thread tolerance for precision fit. Features M4 x 0.7mm coarse thread with 20mm minimum thread length and 50mm overall length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 3mm hex socket drive ensures compatibility with standard industrial tools while the partially threaded rod type provides optimal clamping force distribution.
