These Lag Screws, or Lag Bolts as many call them have coarse threads meant to hold similar to a wood screw. Ours are top quality, with a guaranteed 655 Silicon Bronze alloy, a clean hex head, and sharp cut threads. They're perfect for classic wooden boat building, conquering jobs such as attaching floors to a keel or mounting a stuffing box.
Silicon Bronze is the alloy of choice when fastening below the waterline, for use on a classic vessel, or for any task that requires superior corrosion resistance.
