Professional Applications & Engineering Value
Engineered specifically for demanding environments, these 651 Silicon Bronze hex head screws solve critical corrosion challenges in marine hardware, chemical processing equipment, and coastal infrastructure. The 3/8"-24 UNF fine thread configuration provides superior resistance to vibrational loosening while maintaining 70,000 psi tensile strength - crucial for structural applications where failure is not an option. The external hex drive accommodates high installation torque without stripping, while the Rockwell B70 hardness ensures durability against wear and deformation. These fully threaded screws offer maximum versatility for applications requiring full-length engagement, making them ideal for marine fittings, pump assemblies, and saltwater-exposed structures where corrosion resistance directly impacts operational safety and maintenance intervals.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 3/8"-24 UNF fine threads in right-hand orientation. Complies with ASME B18.2.1 dimensional standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. The silicon bronze material maintains consistent mechanical properties including 70,000 psi tensile strength and Rockwell B70 hardness throughout the fastener.
