ABSTRACT:
A method of making vehicle bumper shims preferably using a progressive die wherein the areas which receive the clamping bolts are built up with separate pieces of the same temper steel commonly used to make a shim of one piece flat shim, and which are spot welded to the base piece and produce a shim of the same general type as shown in Farnam et al., U.S. Pat. No. 4,160,561, but which can be tailored to varying thicknesses as required and most importantly, torque retention properties at least as high as a one piece flat shim. The invention includes also the articles produced by the above method.
