Professional Applications & Engineering Value
This M4 socket head cap screw delivers critical engineering solutions where vibration loosening and corrosion compromise assembly integrity. The nylon patch locking technology creates permanent thread friction that eliminates the need for secondary locking components, reducing installation time and maintenance costs. Manufactured from 18-8 stainless steel with 70,000 psi tensile strength, it withstands dynamic loads in machinery, automotive, and electronics applications. The metric coarse thread (M4 x 0.7mm) and Class 6g tolerance ensure precise fitment in tapped holes, while the hex socket drive provides reliable torque transmission in space-constrained designs. These socket head cap screws maintain performance across temperature extremes from -70° to 250°F, making them ideal for outdoor equipment, industrial automation, and precision instrument manufacturing.
Specification Summary & Compliance
This socket head cap screw features M4 x 0.7mm coarse metric threading with Class 6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. Manufacturing conforms to DIN 912/ISO 4762 specifications for socket head cap screws, guaranteeing consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial components.
