• Secure and precise installation with a 17 mm hex drive and standard socket head profile, allowing for high torque application without slippage.
• Optimized thread engagement using coarse M20 x 2.5 mm threads and Class 5g6g fit, providing quick assembly and vibration resistance.
• Versatile partial threading over 52 mm, offering flexibility for applications requiring both clamped and unthreaded sections.
• Global compliance assurance meeting DIN 912/ISO 4762 standards, RoHS 3, and REACH, ensuring safety and regulatory adherence.

Professional Applications & Engineering Value

This M20 socket head cap screw is engineered to address critical challenges in heavy machinery, automotive assemblies, and structural frameworks where high tensile strength and corrosion resistance are paramount. The black-oxide alloy steel construction combats rust and wear, while the coarse metric thread (M20 x 2.5 mm) ensures rapid, secure fastening even in vibrating conditions. With a 17 mm hex drive and partially threaded design, it simplifies maintenance and provides precise clamping force distribution, reducing the risk of joint failure. Ideal for industrial fasteners in demanding sectors, it enhances equipment longevity and operational safety without compromising on DIN 912/ISO 4762 specifications.

Specification Summary & Compliance

The screw adheres to Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. It complies with DIN 912 (identical to ISO 4762) for socket head cap screws, with a right-hand, coarse thread profile. Regulatory conformance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances for safe industrial use.
