Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw delivers critical performance in demanding industrial applications where corrosion resistance and structural integrity are paramount. The hot-dipped galvanized steel construction provides a thick, durable barrier against moisture and chemicals, significantly extending service life in outdoor or corrosive environments. The partially threaded design concentrates clamping force where needed most, preventing joint loosening under vibration while the coarse UNC threading ensures rapid installation in steel, wood, and other common substrates. With 60,000 psi tensile strength and external hex drive, these screws withstand high tensile loads and permit secure tightening with standard wrenches, making them ideal for structural framing, machinery assembly, and heavy equipment maintenance where reliability cannot be compromised.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit with 3/8"-16 UNC coarse thread specifications and 1-1/2" length. Manufactured in accordance with ASME B18.2.1 standards and ASTM A307 material requirements. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
