Professional Applications & Engineering Value
This 651 Silicon Bronze hex head screw addresses critical corrosion challenges in marine, coastal, and industrial environments where saltwater, chemicals, and moisture rapidly degrade ordinary fasteners. The UNC coarse thread pattern combined with full threading provides exceptional pull-out resistance in wood, composite, and softer metals, while the external hex drive accommodates high-torque installation without cam-out issues. Engineered with 70,000 PSI tensile strength and Rockwell B70 hardness, these marine grade bronze screws maintain structural integrity in vibration-prone applications, making them ideal for boat building, offshore structures, chemical processing equipment, and architectural installations where long-term reliability is paramount.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 1/2"-13 UNC coarse threads and full threading along the 1-1/2" length. Complies with ASME B18.2.1 dimensional standards for hex head screws. Meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances. The external hex drive features 3/4" head width and 5/16" head height for standardized tool compatibility across industrial applications.
