Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M20x2.5 Class 8.8 low profile socket head cap screws solve critical assembly challenges where space constraints meet high-strength requirements. The black-oxide alloy steel construction provides exceptional corrosion resistance while maintaining Rockwell C20 hardness for long-term reliability. The 17mm hex drive with pilot recess ensures precise installation alignment, preventing damage to mating components and reducing assembly time. With their partially threaded design and metric coarse thread pattern, these fasteners deliver optimal clamping force in heavy machinery, automotive systems, and industrial equipment where vibration resistance and structural integrity are paramount.
Specification Summary & Compliance
This M20x2.5 metric screw features Class 6g thread fit tolerance for precise engagement, with a minimum thread length of 46mm and overall length of 90mm. Manufactured to DIN 6912 specifications for dimensional accuracy and performance consistency. The fastener is RoHS 3 (2015/863/EU) compliant and meets Class 8.8 strength requirements with right-hand metric coarse thread spacing of 2.5mm pitch, ensuring compatibility with standard industrial components and applications.
