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 blue-dyed zinc plating extends service life in harsh industrial environments, minimizing maintenance needs.
- High hardness rating (Rockwell C37) provides excellent wear resistance and durability under repetitive loads.
- Precision coarse threading (M8 x 1.25mm) enables quick installation and secure fastening in various materials.
- Partially threaded design allows for controlled clamping force and reduced thread damage during assembly.
- Standard hex drive (6mm) offers compatibility with common tools and prevents cam-out for efficient torque application.
- Compliance with international standards (DIN 912/ISO 4762) guarantees dimensional accuracy and interchangeability.
Professional Applications & Engineering Value
This Class 12.9 socket head cap screw delivers critical performance in demanding applications where failure is not an option. The blue-dyed zinc-plated alloy steel construction provides both corrosion protection and visual identification in complex assemblies. Engineered with coarse metric threading (M8 x 1.25mm), it offers superior resistance to vibration loosening while maintaining easy installation in tough materials. The partially threaded configuration ensures precise clamping without compromising thread integrity. Ideal for heavy machinery, automotive systems, and industrial equipment, this high-strength fastener solves common engineering challenges including thermal expansion, dynamic loading, and corrosive environment exposure.
Specification Summary & Compliance
Manufactured to exacting DIN 912/ISO 4762 standards with Class 5g6g thread fit tolerance for consistent dimensional accuracy. The screw features M8 x 1.25mm coarse threading with minimum thread length of 28mm and total length of 80mm. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across global markets. The Class 12.9 strength rating and Rockwell C37 hardness meet rigorous industrial requirements for reliability and performance.
