; I have the dimensions of the tab, and I can create a slot that will fit, but I'm mostly estimating.Your discussion above about the hole size for round and rectangular pins made me think to post this question here.

. Call your salesperson if you required a finished hole size less than 0.004″. If your hole tolerances are zero, then Imagineering will assume that you are OK with our default hole tolerance. +/- 0.004″ Standard Spec
