Professional Applications & Engineering Value
Engineered for marine applications and corrosive environments, these silicon bronze hex head screws solve critical durability challenges where standard fasteners fail. The 651 silicon bronze composition provides exceptional resistance to saltwater corrosion and chemical exposure, while maintaining 70,000 PSI tensile strength under continuous load. The fully threaded UNC coarse pattern (3/8"-16) ensures maximum pull-out resistance in wood, composite, and soft metal applications, preventing loosening from vibration. With external hex drive compatibility, installation efficiency is maximized using standard industrial tools, making these hex head screws ideal for boat building, offshore structures, and chemical processing equipment where reliability cannot be compromised.
Specification Summary & Compliance
This 3/8"-16 UNC silicon bronze hex head screw features precision Class 2A thread fit with coarse thread spacing, manufactured to exact inch system dimensions (1 3/4" length, 9/16" head width). The fastener complies with ASME B18.2.1 mechanical standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both mechanical performance and environmental responsibility for industrial applications.
