- Standard hex socket drive (17mm) offers secure tool engagement, high torque transmission, and a clean, flush head profile.
- Fully threaded design maximizes grip length and provides uniform clamping force along the entire fastener.
- Compliance with DIN 912/ISO 4762, RoHS 3, and REACH guarantees international quality standards and material safety for regulated industries.
Professional Applications & Engineering Value
This M20 socket head cap screw is engineered to solve critical challenges in industrial assembly. The core value lies in its 316 stainless steel material and passivated finish, which work in tandem to provide exceptional resistance to chemicals, saltwater, and other corrosive agents, significantly reducing maintenance and replacement costs. The coarse metric thread and Class 6g fit ensure reliable performance in high-vibration environments, preventing loosening in machinery, automotive systems, and marine equipment. The hex drive design allows for installation in confined spaces where wrench clearance is limited, making it a versatile and durable industrial fastener for critical connections.
Specification Summary & Compliance
This fastener features a Class 6g thread fit per standard metric tolerances. It is manufactured to conform to the dimensional and mechanical specifications of DIN 912 and ISO 4762. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances for use in various global markets.
