Professional Applications & Engineering Value

This M18 hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents rust formation in chemical processing, marine, and outdoor applications, significantly extending service life. The coarse metric thread with 2.5mm pitch maintains secure fastening in high-vibration machinery, while the partial threading concentrates stress away from the head-to-shank junction. With 80,000 psi tensile strength, these DIN 931 compliant screws provide reliable performance in structural steelwork, heavy equipment assembly, and infrastructure projects where failure is not an option. The external hex drive accommodates standard wrenches for rapid installation and maintenance access in confined spaces.

Specification Summary & Compliance

This 150mm length screw features precision M18 x 2.5mm coarse threads with Class 6g thread fit according to ISO metric standards, ensuring dimensional accuracy and interchangeability. Manufacturing strictly adheres to DIN 931 specifications for hex head bolts, guaranteeing consistent quality and performance. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for global industrial supply chains and environmentally conscious operations.
