Professional Applications & Engineering Value

This M20 socket head cap screw is engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and structural frameworks. Manufactured from 18-8 stainless steel, it offers excellent resistance to rust and oxidation, which is vital for equipment exposed to moisture or chemicals. The coarse 2.5 mm pitch metric thread and Class 6g thread fit enable quick, reliable installation, reducing assembly time and preventing thread stripping. The hex drive design allows for high torque application with standard tools, ensuring a secure hold in high-vibration environments. Its partially threaded shank provides focused clamping force, making it ideal for components requiring precise unthreaded grip areas, thereby enhancing the longevity and safety of your mechanical systems.

Specification Summary & Compliance

This screw adheres to DIN 912/ISO 4762 specifications, ensuring precise dimensions including a 30 mm head diameter, 20 mm head height, and 100 mm overall length. The metric thread features a Class 6g tolerance for consistent fit, with a right-hand, coarse thread of M20 x 2.5 mm. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
