Professional Applications & Engineering Value
Engineered specifically for challenging environments, these 651 Silicon Bronze hex head screws deliver exceptional performance where corrosion resistance is critical. The combination of 70,000 PSI tensile strength and Rockwell B70 hardness provides structural integrity in marine applications, chemical processing plants, and offshore installations. The coarse UNC threading ensures reliable engagement in softer materials and resists loosening under vibration, while the external hex drive facilitates quick installation with standard wrenches. These fully threaded screws maintain consistent clamping force across the entire 1-1/4" length, making them ideal for structural connections, marine hardware, and industrial equipment exposed to saltwater, chemicals, and atmospheric corrosion.
Specification Summary & Compliance
This 1/2"-13 UNC silicon bronze hex head screw features precise Class 2A thread fit tolerances and coarse thread spacing for optimal performance. Manufactured to ASME B18.2.1 specifications, the fastener ensures dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and meets REACH (EC 1907/2006) requirements for chemical safety, making it suitable for global industrial applications with strict environmental regulations.
