Good Screws
Product was ordered and arrived as expected. Screws were of good quality and worked exactly as I expected.

Works just like "Tap" brand screws. Strong, Sturdy, Cheaper.
LONG STORY SHORT: I needed a bunch of Concrete Screws, and these have done the trick. I've driven several into concrete (after using the included masonry bit) and no complaints what-so-ever. They feel strong and sturdy, seemingly good quality. They worked great installing a 65" TV mount onto a cinderblock wall. The screws hold strong with no wiggle. Glad I have a ton of them.

Works as tapcon screws replacement
These screws work just as well as the tapcon brand, have not had any issues using or holding once placed

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.

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...
