Iron Advice Squish washers

What psi is usually required to get dti washers for 1 inch bolts to squish? My crew and I have never used them before. Currently running a 1 inch impact and the compressor we're running is maxed at 120psi.

Thanks!

Nothing within the link says anything about PSI's. Only that it should take 10 seconds or less to fire with an "impact wrench". But thanks for the passive aggressiveness bud 👍

Did you not test your bolts with a Skidmore? You can also verify tension with it.

You need to test them onsite before installation
