• Superior corrosion resistance from blue-dyed zinc plating protects against rust and extends service life in harsh industrial environments.
• Precise hex drive compatibility with a 14mm drive size allows for secure, high-torque installation using standard tools, reducing assembly time.
• Optimized thread design with M16x2mm coarse pitch and Class 5g6g fit provides quick, stable engagement and vibration resistance.
• High hardness rating (Rockwell C37) maintains thread integrity and head durability, even after repeated use.
• Full threading along the 25mm length offers versatile fastening options and uniform stress distribution.
• Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability for global engineering projects.

Professional Applications & Engineering Value

This Class 12.9 socket head cap screw is engineered to address demanding industrial challenges where fastener failure is not an option. The blue-dyed zinc-plated alloy steel construction provides a durable barrier against moisture and chemicals, ideal for machinery, automotive assemblies, and heavy equipment exposed to corrosive conditions. With a coarse thread pitch of 2mm and right-hand thread direction, it ensures rapid installation and high resistance to loosening under dynamic loads. The fully threaded M16 design and hex drive enable uniform clamping force and easy access in confined spaces, reducing maintenance downtime. By meeting DIN 912/ISO 4762 specifications, it delivers consistent performance in precision engineering applications, from manufacturing jigs to structural frameworks.

Specification Summary & Compliance

This product adheres to Class 5g6g thread fit tolerances per metric standards, ensuring precise engagement. It conforms to DIN 912 (identical to ISO 4762) for dimensional accuracy, including head diameter (24mm), head height (16mm), and length (25mm). Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms its environmental safety and suitability for regulated industries.
