• Precise and secure fastening with Class 6g thread fit and coarse M16x2mm threading, reducing the risk of loosening in vibration-prone applications
• Efficient installation and removal with 10mm hex drive and flat head design, allowing for high torque application and flush mounting
• Full-thread engagement along the 30mm length, providing maximum grip and uniform stress distribution in assembled components
• Reliable compliance with DIN 7991 standards, ensuring dimensional accuracy and interchangeability in metric fastener systems
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting global regulatory requirements for industrial components

Professional Applications & Engineering Value

This M16 flat head screw is engineered to address critical challenges in heavy-duty assembly, where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides a robust barrier against corrosion, extending service life in outdoor or chemically exposed settings like machinery frames, structural steel connections, and industrial equipment. The Class 10.9 strength grade and fully threaded design ensure that the fastener maintains clamp force under dynamic loads, reducing maintenance needs. With a 90° countersink angle and hex drive, it offers seamless integration into pre-drilled surfaces, making it ideal for applications requiring a smooth finish and high torque capability, such as in automotive chassis, construction assemblies, and manufacturing jigs.

Specification Summary & Compliance

This fastener features M16x2mm coarse threads with Class 6g thread fit for precise metric assembly, and is manufactured to DIN 7991 specifications for dimensional consistency. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. The Rockwell C32 hardness and 120,000 psi tensile strength validate its performance in high-stress applications, while the right-hand thread direction and standard flat head profile guarantee compatibility with common industrial tools and components.
