Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M6 flat head screw addresses critical challenges in machinery, automotive, and structural assemblies. The zinc-plated alloy steel material combats corrosion, extending service life in moist or chemically exposed settings. With a Class 10.9 strength rating and 120,000 psi tensile strength, it prevents failures under heavy loads and vibrations. The fully threaded design and coarse thread pitch enhance grip in soft materials or where rapid assembly is needed, while the hex drive ensures torque accuracy without stripping. Ideal for countersunk fastening in metal frames or equipment, it provides a secure, low-profile connection that meets DIN 7991 specifications for reliability.

Specification Summary & Compliance

This screw features M6 x 1 mm metric coarse threads with a Class 6g tolerance for precise fit, and is fully threaded over the 70 mm length. It complies with DIN 7991 manufacturing standards and is certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations. The Class 10.9 grade confirms high tensile and hardness properties (Rockwell C32), suitable for critical engineering uses.
