Professional Applications & Engineering Value

This Grade 5 zinc-plated steel hex head screw is engineered to address critical challenges in heavy-duty industrial applications, such as machinery assembly, structural frameworks, and automotive components. The zinc plating provides a protective barrier against corrosion, essential for outdoor or humid conditions, while the Rockwell C22 hardness ensures durability under repetitive stress. Featuring coarse UNC threads and a Class 2A fit, it offers quick, reliable fastening with reduced risk of cross-threading. The external hex drive allows for high-torque installation using standard tools, and the serrated flange locks securely to prevent loosening from vibrations, making it ideal for dynamic loads in construction and manufacturing sectors where safety and longevity are paramount.

Specification Summary & Compliance

This fastener adheres to precise dimensional standards with UNC coarse threads in a Class 2A fit for consistent tolerance. It meets IFI 111/SAE J429 specifications for Grade 5 mechanical properties, ensuring reliable strength and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it is free of restricted substances, supporting environmentally responsible procurement and use in global markets.
