Good value for the money
These are great concrete screws but over time they will rust off and break ....I use them all the time and for most jobs outside....I do like Stainless Steel better for anything outside that will get wet...

Recommend for most projects
They are decent quality but not TapCon level quality. If you need really heavy duty strength then go with TapCon or equivalent.

Work well in cmu.
Good price and worked well. I've used about half in cmu and had no issues. I did already have a tapcon bit but I'm sure the included one would work well.

Works well and priced competitively, significantly less expensive than walk in store option
