Professional Applications & Engineering Value
Engineered for demanding marine, chemical processing, and coastal infrastructure applications, these silicon bronze hex head screws deliver exceptional performance where corrosion resistance is critical. The 651 silicon bronze material provides natural resistance to saltwater corrosion and stress cracking, significantly extending service life in aggressive environments. The 1/2"-13 UNC coarse thread configuration ensures rapid installation and reliable holding power in wood, metal, and composite materials. With full threading along the 5 1/2" length, these screws offer maximum engagement depth and adjustability for structural connections, marine hardware, and industrial equipment subjected to vibration and dynamic loads.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit with 1/2"-13 UNC coarse thread specifications, manufactured to ASME B18.2.1 standards for dimensional accuracy and mechanical properties. The fastener maintains Rockwell B70 hardness and 70,000 psi tensile strength throughout the 5 1/2" fully threaded length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance management for global industrial applications.
