The hole size in the wheel for the Trigo or PS nuts & maybe others using a .750 nut is is 49/64ths, creating a .0156 clearance. The depth in the wheel may vary depending on whether the holes are machined after the back spacing is set or before. Occasionally after torquing all the "Nuts" you can find that the wheel will not fit over the protruding pattern because for one reason or another the nuts are not in a perfectly circular pattern. If this happens a "rap" with a block of wood and a hammer can move an individual stud or nut the minute amount necessary to effect the wheel fitting over the circular group of nuts. This is a rare case. There was a tool available that had the 5 hole pattern matching the wheel which was fit over the nuts prior to their final torquing to assure they stayed in the correct pattern to allow fitament of the wheel.
