Professional Applications & Engineering Value
These 651 Silicon Bronze hex head screws deliver exceptional performance in corrosive environments where standard steel fasteners fail. The silicon bronze composition provides natural resistance to saltwater, chemicals, and atmospheric corrosion, making them ideal for marine hardware, chemical processing equipment, and coastal infrastructure. The coarse UNC threading ensures reliable engagement in softer materials and faster installation times, while the external hex drive accommodates high-torque applications without stripping. With 70,000 psi tensile strength and Rockwell B70 hardness, these screws maintain structural integrity under heavy loads and vibration, solving critical fastening challenges in industrial maintenance, water treatment systems, and offshore applications where corrosion resistance and mechanical reliability are paramount.
Specification Summary & Compliance
This 1/2"-13 UNC hex head screw features precise Class 2A thread fit tolerances and fully threaded 1" length with coarse spacing. Manufactured to ASME B18.2.1 dimensional standards for consistent quality and interchangeability. Compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility and global market acceptance.
