Say I have an AN3 bolt. The grip measures 0.189" with a caliper. I install it into a 0.189" reamed hole. However, there's a radius between the grip and the bearing surface of the bolt head, so the head bearing surface (dimension H) will not sit flat on the sheet. Instead, the bolt will rest on the radiused portion:
That seems undesirable. Is this a practical concern? Would the hole need to be slightly countersunk to accept the radius portion of the bolt?
Thanks in advance.
