I wasn't 'debating', just stating what I found from personal experience. Not everything is an argument, it's called talking and sharing.

Pretty sure those are the same type I used to bolt down my gun safes to the concrete floor.

Yup, you have to smack the bolt with a hammer to spread the wedge and grip the hole. Then just run the nut down and tighten the flange or whatever you are securing to the concrete.

Hilti makes em too.

NOT arguing.....but that's backwards. Hammering the bolt only gets it into the hole. The tightening of the nut is what actually pulls the bolt up, and spreads the wedge. If you just hammer it without actually cranking on a nut, it won't be properly set.

To get the expansion cone to make initial contact with the walls of the hole, you hit it with a hammer.

I've never done it, but I had a crew install them on a vent silencer support I designed as a young engineer. No epoxy. They smacked it a couple wacks with a heavy hammer, then tightened the nut. The crew was a very experienced Brown and Root crew.

I've done thousands of qwik bolts and drop ins. Regardless, you have to hammer it to fully sink the qwik bolt into the hole, then tighten the nut.

Either way, I've done enough at work that I never want to touch one on my own time.

My apologies.
Looks like the hammering in is to drive the outer sleeve into the hole and get the splines to engage/cut into the wall, then the tightening does the expansion of the wedge.

If your hole is to spec, they usually need a few light taps to ensure they are bottomed put. If you hammer drill isnít up to the job, the anchors might fall in.

I have a 8 oz ball pein hammer in my roto hammer drill case, a gentle tap is all it takes.

Note these are for concrete only, the sleeve style will do block, these wonít.
