Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI ensures reliable performance under extreme loads, reducing the risk of fastener failure in demanding applications.
- Superior corrosion resistance from the blue zinc plating protects against rust and environmental degradation, extending service life in harsh industrial settings.
- High hardness rating (Rockwell C37) provides excellent wear resistance and maintains thread integrity during repeated assembly and disassembly.
- Precise Class 5g6g thread fit guarantees smooth installation and secure fastening, minimizing play and vibration loosening in machinery.
- Partially threaded design offers optimal grip and clamping force control, ideal for applications requiring specific unthreaded shank sections.
- 10mm hex drive socket head allows for high-torque installation with standard tools, facilitating quick and efficient assembly in confined spaces.
- Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability, providing peace of mind for quality-critical projects.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Class 12.9 socket head cap screws deliver unmatched reliability in high-stress environments such as automotive assemblies, machinery frames, and construction equipment. The blue-dyed zinc-plated alloy steel construction combats corrosion while the metric coarse thread (M12 x 1.75mm) ensures rapid installation and robust holding power. With a partially threaded rod and 65mm length, they provide precise clamping where full threading isn't required, reducing material stress. The 10mm hex drive enables secure tool engagement, preventing stripping and ensuring consistent torque application in repetitive maintenance cycles.
Specification Summary & Compliance
This M12 socket head cap screw features a 1.75mm coarse pitch thread with Class 5g6g tolerance for precise fit, manufactured to DIN 912 and ISO 4762 specifications. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental safety, with a minimum thread length of 36mm and overall 65mm length.
