Professional Applications & Engineering Value

Engineered for demanding environments, this 1/2"-13 UNC hex head screw in 651 Silicon Bronze addresses critical challenges in marine, chemical processing, and outdoor infrastructure. The coarse thread design prevents cross-threading and provides rapid installation in wood, metal, and composite materials, while the fully threaded configuration ensures uniform stress distribution. With 70,000 psi tensile strength and inherent corrosion resistance, it eliminates premature failure in saltwater or high-humidity settings. The external hex drive facilitates secure fastening in confined spaces, making it a preferred choice for industrial and marine-grade assemblies where reliability and regulatory compliance are paramount.

Specification Summary & Compliance

This screw features a 1/2"-13 UNC coarse thread with Class 2A thread fit for precise dimensional tolerance. It is manufactured in accordance with ASME B18.2.1 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability for industrial procurement.
