3/8" Stainless Steel Torque Washers

Torque washers increase the bearing area under a carriage bolt’s head, and prevent it from spinning as it is tightened. They are ideal for use in constructing swing sets, docks and decks. Torque washers have four prongs that bite into the lumber to prevent spinning, and a central square hole for the carriage bolt under-head square “nut.” They work best with softwoods and man-made composite lumber and are not likely to give good results with tropical hardwoods like Ipe.
