Another trick is to screw on a nut before you cut the threads. After cutting, removing the nut (usually with a wrench) will "clean up" the threads at the end. Doesn't do wonders for the nut, though.

It bugged me that the clevis holes weren't big enough for the supplied 2-56 bolts. Seemed they could've at least mentioned it in the instructions. It looked like a simple operation, until I tried attaching the wires.
