Professional Applications & Engineering Value

This M6 hex head screw is engineered from Class 8.8 steel to address critical challenges in heavy machinery, automotive assemblies, and structural frameworks. The partially threaded design minimizes stress concentration points, while the coarse metric thread with 1 mm pitch ensures rapid installation and high resistance to loosening under dynamic loads. With a Rockwell C21 hardness and 110 mm length, it provides robust clamping force in thick materials, reducing the risk of joint failure. The external hex drive allows for high-torque application, making it ideal for industrial settings where reliability and repeatability are paramount. Fully compliant with ISO 4014 DIN 931, this screw delivers consistent quality for OEM and MRO operations.

Specification Summary & Compliance

This fastener meets ISO 4014 DIN 931 specifications, featuring M6 x 1 mm coarse threads with Class 6g tolerance for precise fit. The partially threaded shank has a minimum thread length of 18 mm, and the external hex head measures 10 mm in width and 4.2 mm in height. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe and sustainable use in global markets.
