Abstract
An apparatus for aligning and shimming plates being anchored to a substratum having a plurality of threaded anchor holes coaxially aligned with corresponding apertures and coaxial threaded bores through each plate. The apparatus includes an external threaded cylindrical shim having a shimming surface and a second (outer) surface adapted to accept rotary force for rotational movement and adjustment of the separation produced by the shim between the substratum and the anchored plate. For anchoring, the 2nd surface of the shim further includes a counterbored or countersunk hole having a shoulder including a narrower passthrough aperture aligned with the threaded anchor hole, through which an anchor screw extends for rotational mating with the threaded anchor hole. The anchor screw also has a head wider than the passthrough aperture, and adapted to accept rotary force for rotational movement and fixing the shim in place. The apparatus may also include a cap covering the anchor screw head within the counterbored or countersunk hole, to provide a more continuous planar surface and to prevent grit or other unwanted material from collecting in the hole. The apparatus may also include an ad…
