Heavy duty 8-inch hold fast clamps designed to secure workpieces to your workbench top. These bench dog clamps work with standard 3/4-inch dog holes, making them a versatile addition to any woodworking setup. Each clamp features a 3-1/2 inch reach and a rough as-cast finish that grips firmly without marring your stock. Simply drill an 11/16 inch hole in your workbench, wedge in the holdfast, and tap with a mallet to secure. A quick tap on the backside releases the clamp. Sold as a pair.
