Workbench Holdfast Bench Clamps
Holdfasts have in use for centuries to hold boards to the top and side of workbenches to allow hands-free planning, carving, drilling, sawing, routing, etc. Holdfasts are perfect for projects that require frequent re-positioning. These are made from ductile cast iron. To use, simply drill 3/4" holes in a workbench, insert and hit with a mallet in the center of the head. To release, tap the back side of the clamp. The shafts of these are left slightly rough to grab the hole better. Holdfasts work best in benchs at least 2" thick. There have been lots of complaints about cast holdfasts breaking when hit. In our tests, we tried to break these by hitting with a 4 pound sledge hammer, but were unsuccessful. These should easily hold a 3" to 4" thick board securely on you bench. These are best used in pairs. Available in singles (1) or pairs (2).
