Flat and Tapered Beam Torque Wrenches The error proofing industry started with a deflecting beam wrench built and sold by Paul A. Sturtevant. That was 1924. Highly accurate, very easy to use, and so durable they often last for decades - and decades! The special alloy steel beam is ground to a rate of deflection with the use of dead weights, rather than a dimensional tolerance. This process is time consuming and very labor intensive, but the result is a tool that remains accurate as long as the beam is intact and the pointer is on zero under no-load condition. The flat shape of the beam insures the wrench remains at a right angle to the fastener, reducing or eliminating side-loading error. This unique taper-grinding distributes stress evenly along the entire length of the beam, extending tool life indefinitely. With a minimum of moving parts, these tools are virtually repair and maintenance free.
