1/2" x 3" Hex Lag Bolts Silicon Bronze

1/2" x 3" hex head lag bolts (lag screws) in silicon bronze to ASME B18.2.1 — coarse wood-screw thread and gimlet point for driving into timber with a wrench. 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. Sold in production-volume bulk packs.
