Abstract
A base plate for press fitting into a boss hole of a predetermined nominal diameter. The base plate has a flange and a hub extending from a region at which the hub meets the flange to an outer end of the hub. The hub has a number of vertical slots cut through the hub extending from the outer end of the hub part way or all the way to the region at which the hub meets the flange a space between slots determining boundaries of a prong. The hub has an outer diameter which is greater than the predetermined nominal diameter or alternatively the hub has an outer diameter at the region at which the hub meets the flange which is not greater than the predetermined nominal diameter, in which case each the prong extends outward to a prong outer diameter which is greater than the predetermined nominal diameter. Also the base plate may have a corner relief that circumscribes the region at which the hub meets the flange.
