Our solid 651 silicon bronze hex cap screws, often referred to as hex head bolts or tap bolts, are a solid bronze alloy, specifically CS65100 silicon bronze. All of our hex cap screws are fully threaded with a standard imperial coarse thread, and meet SAE specifications as well as ASME B18.2.1 and ASTM F468 with grade markings on the heads.

Non-magnetic, electrically conductive, high strength, and extremely corrosion resistant properties make these solid bronze hex bolts excellent for a variety of uses including:

  • Use on a boat where corrosion resistance from seawater is paramount
  • Use in electrical generation or in the power and energy industry for their highly conductive, high strength, and corrosion resistance
  • In general construction, where proximity to salt spray or other corrosive environments is of concern
  • Use in water treatment plants, where they will resist corrosion from chlorine or other treatment chemicals
  • Use in electrical grounding
  • Use on dams, dikes, and levies where they won't corrode and are easily removed years down the line.
