Hex head cap bolts in silicon bronze to ASME B18.2.1 dimensions. Short lengths are threaded full length; longer lengths carry the standard ASME thread length shown for each length. Silicon bronze resists saltwater corrosion, is non-magnetic and will not rust, which makes it the traditional choice for boatbuilding, docks and marine hardware, and for exterior wood and architectural work where it weathers to a natural patina. 14 lengths (3/4" to 6"). Sold in production-volume bulk packs.
