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...

They Screw Right In
This is the first time I tried to use Tapcon-type concrete screws and I was amazed how easily they screwed right into my concrete block wall. I used a small Black and Decker battery operated drill to do it and there was no strain or effort required. I drilled pilot holes first, using my DeWalt masonry drill bit and it was essential to do that. There is a masonry drill bit included with the screws but it looked like it wouldn't last long so I used my DeWalt bit but maybe the free one is better than I thought. I tried to make the final turns with a screwdriver and it was a lot harder, so maybe the key is to use a drill. Whatever, I certainly recommend these screws and would buy more if I need them.

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.

The right screw for the right
Item as described. Fast shipping. Screws did their job well. Perfect size for securing a 2x4 to the concrete floor.
