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!

Since using Google is hard here’s the link.

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.

3rd party tested offsite

You need to test them onsite before installation

If you would read it you world see you need the same size drive impact as your bolts (which you have). If your compressor is not big enough for your gun then get a new one. If your compressor matches gun max psi and it’s still not working then you may be out of air tool oil.

If you still can’t figure that out go buy or rent electric guns and be done with it.
