Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide coating prolongs service life in harsh industrial environments.
- High hardness rating (Rockwell C37) provides excellent wear resistance and maintains thread integrity under heavy loads.
- Precision Class 5g6g thread fit guarantees smooth installation and secure fastening in demanding assemblies.
- Fully threaded design offers consistent clamping force along the entire 90mm length for uniform load distribution.
- Standard hex drive (17mm) allows for easy installation with common tools, reducing assembly time and effort.
- Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability in global engineering projects.
Professional Applications & Engineering Value
This M20 socket head cap screw delivers critical engineering value through its black-oxide alloy steel construction and Class 12.9 strength rating, making it ideal for heavy machinery, automotive assemblies, and structural frameworks where vibration and dynamic loads are common. The coarse thread (2.5mm pitch) provides superior resistance to loosening and enables quick installation in tough materials. With its fully threaded metric design and right-hand thread direction, it ensures maximum grip and uniform stress distribution, solving common issues of joint fatigue and misalignment in industrial applications. The combination of high tensile strength and corrosion-resistant coating addresses the need for durability in exposed or high-moisture environments, reducing maintenance cycles and downtime.
Specification Summary & Compliance
This fastener features precise Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and compatibility. It is manufactured to meet DIN 912 and ISO 4762 specifications for socket head cap screws, guaranteeing consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use without hazardous substances.
