Key Features & Benefits at a Glance
- Exceptional strength and durability with Class 12.9 rating and 170,000 psi tensile strength for reliable performance in high-stress applications.
- Superior corrosion resistance provided by zinc-flake coating, extending service life in harsh industrial environments.
- Precise torque transmission enabled by 6mm hex socket drive and standard socket head profile for secure, slip-free installation.
- Optimal thread engagement with Class 5g6g thread fit and M8x1.25mm coarse thread for quick assembly and vibration resistance.
- Full-threaded design ensures maximum grip and load distribution along the entire 35mm length.
- High hardness rating of Rockwell C37 minimizes wear and deformation under heavy loads.
- Broad compatibility with standard tools and components due to compliance with DIN 912 and ISO 4762 specifications.
Professional Applications & Engineering Value
This M8 socket head cap screw delivers critical engineering value in demanding applications where failure is not an option. The zinc-flake-coated alloy steel construction solves common industrial pain points by combining exceptional corrosion resistance with the highest strength grade available for metric fasteners. The fully threaded design and Class 5g6g thread fit ensure reliable clamping force in machinery, automotive assemblies, and heavy equipment, while the hex socket drive allows for high-torque installation in confined spaces. Engineers specify these Class 12.9 screws for critical joints subject to dynamic loads, vibration, and harsh environments, where the combination of 170,000 psi tensile strength and compliant coatings prevents premature failure and maintenance downtime.
Specification Summary & Compliance
This socket head cap screw features M8x1.25mm coarse metric thread with Class 5g6g tolerance, 35mm length, and 6mm hex drive. Manufactured to DIN 912 and ISO 4762 standards with ASTM B117 corrosion testing compliance. Fully meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
