Get rid of clamps and bolts and replace them with Invert-A-Bolt™ (IVB) Fasteners*. These unique, patented, flush-mounted captive fasteners, eliminate obstructions to machining, reduce vibration in your setup, and most importantly lower your cost by cutting setup times and improving your efficiencies. Think of them as a quick change bolt. Never waste time looking for the "right" bolt again. Never waste time by grinding a bolt to size again. Never stop your machine to change clamps again. Never "warp" your part because a clamp has been misused again. These bolts are always there in your fixture and always the same length. Simply screw the larger diameter (the housing) into the fixture plate and bring the inner diameter (the stud) up into your stock material for a superior holding solution.
