Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, minimizing failure risks.
- Superior corrosion resistance from zinc-flake coating protects against harsh industrial environments, extending service life.
- High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity during repeated use.
- Precise hex drive (4mm) allows for secure tool engagement, reducing slippage and enabling efficient installation in confined spaces.
- Coarse thread pitch (0.8mm) facilitates quick assembly and disassembly, saving time in maintenance and production cycles.
- Full threading ensures consistent clamping force along the entire length, ideal for applications requiring uniform load distribution.
- Compliance with international standards like DIN 912 and ISO 4762 guarantees dimensional accuracy and interchangeability.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this M5 socket head cap screw combines Class 12.9 alloy steel with a zinc-flake coating to address common challenges like vibration loosening and environmental degradation. Its fully threaded right-hand design and coarse metric thread enable rapid fastening in machinery, automotive assemblies, and heavy equipment, where high tensile strength and corrosion resistance are critical. The standard socket head profile and 4mm hex drive provide reliable torque transmission, reducing installation errors and enhancing safety in precision engineering applications.
Specification Summary & Compliance
This screw features M5 x 0.8mm coarse threads with a Class 5g6g thread fit for precise dimensional tolerance. It meets DIN 912 and ISO 4762 specifications for socket head cap screws, ensuring consistent quality. Additionally, it complies with ASTM B117 for corrosion testing, RoHS 3 (2015/863/EU), and REACH (EC 1907/2006) regulations, supporting environmentally responsible manufacturing practices.
