how much do you oversize hole for simpson epoxy
The drill from Simpson for setting bolts and rebar in concrete with epoxy is pretty much. 1. Drill the properly oversized hole. The hole should be 1/8 to 1/4 inch oversized, except for 3/8 all-thread, where they spec it out as 1/16 to 1/8 oversized. 2. Blow it out with oil-free compressed air for at least 4 seconds at a minimum 80psi. The nozzle must reach the bottom of the hole.
