T terrye Well Known Member May 23, 2011 #2 AN833-6D AN833-6D has a 9/16-18 thread. A 9/16" diameter hole is probably sufficient.
AcezHi Active Member May 23, 2011 #3 I wasn't sure if it was a little smaller since my 9/16 step drill wouldn't quite fit in the hole in the prepunched access plate I am replacing.

W Wayne Gillispie Well Known Member May 23, 2011 #4 Like Terry said 9/16" or .5625" Van's pre-punched holes on my large area washers are just a .001 or .002" smaller.
