Professional Applications & Engineering Value

These silicon bronze carriage bolts deliver exceptional performance in demanding applications where corrosion resistance is critical. The square neck design mechanically locks into materials during installation, eliminating rotation issues that compromise joint integrity in wood-to-metal and structural connections. The fully threaded UNC coarse spacing provides superior pull-out resistance in soft materials while enabling quick installation. With silicon bronze construction, these bolts withstand saltwater exposure, chemical environments, and outdoor weathering far better than standard steel fasteners, making them ideal for marine hardware, chemical processing equipment, and coastal infrastructure where durability and regulatory compliance are paramount.

Specification Summary & Compliance

Manufactured to ASME B18.5 standards with Class 2A thread fit for consistent dimensional accuracy. Features 1/2"-13 UNC coarse threads in right-hand direction with full threading. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
