Table 14-2 Steel Construction Manual AISC shows recommended maximum sizes form anchor rod holes. Keeping hole sizes from Table 14-2 requires using adequate plate washer. Since these hole sizes are suggested as the largest permissible sizes, utilizing smaller hole sizes is frequently justified when the anchor-rod assemblies are precisely placed.
Holes aligned with Table C-J9.1 Steel Construction Manual AISC will be covered by F436 washers and do not require additional plate washers.
