What mounting hardware is provided?
We provide four 4-40 x 7/8″ flat head machine screws, with a 100 degree head angle so that the screw heads will not rub on the wheel. We also provide four 4-40 k-lock nuts, four .25″ x .25″ #4 spacers, four .25″ x .31″ #4 spacers, four .014″ thick washers, and four .030″ thick washers. See the product manual for suggested combinations of spacers and washers to use with various popular servo models.
