Professional Applications & Engineering Value
This M20 socket head cap screw is engineered to address critical challenges in heavy machinery, automotive, and precision equipment assembly. The black-oxide alloy steel construction provides excellent corrosion resistance, reducing maintenance needs in humid or chemical-exposed settings. With an extra fine thread (1.5mm pitch) and Class 5g6g thread fit, it offers superior clamping force and vibration resistance, preventing loosening in dynamic applications. The partially threaded rod and high Class 12.9 strength ensure reliable performance under extreme tensile and shear stresses, making it ideal for bolting critical components where failure is not an option. Its compliance with DIN 912/ISO 21269 standards guarantees interchangeability and quality, streamlining procurement for global engineering projects.
Specification Summary & Compliance
This screw features precise metric dimensions, including M20 thread size, 1.5mm pitch, 100mm length, and 52mm minimum thread length, with Class 5g6g thread fit for accurate assembly. It adheres to DIN 912/ISO 21269 manufacturing specifications and is certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and regulatory acceptance in industrial markets.
