Help with garage shelving on concrete walls

I have a small 1 car garage that I am trying to add wall shelving to. The walls appear to be a stucco over cbs block construction. I think they are hollow. I bought these: Tapcon 3/16 in. x 2-3/4 in. Climaseal Steel Flat-Head Phillips Concrete Anchors (75-Pack)-24365 - The Home Depot
They came with a drillbit but it sucked. Even with a decent electric drillit was very slow going. I manage to drill to holes but the screws came right out. Even holding the drill steady it must have wobbled a bit and enlarged the hole. Well I ended up taking the screws back. So what are my alternatives. I'm just trying to attach 3 vertical 2x6's to the wall to anchor the shelving. I want something that will hold some good weight. At least 200 lbs. I'm about to call a pro....

There are a number of different types of anchors that would work, but most of them are going to involve drilling holes in the block.

The tapcons are a good way to go, and I've found them to work very well. But you really need a hammer drill when drilling in concrete or block. In addition to turning the bit, it has an internal mechanism that whacks or hammers the bit slightly as it's turning. Makes a huge difference when drilling concrete.

But obviously you don't want to buy one just for this job...maybe you could borrow one or rent one for an hour.

Another alternative would be concrete nails. They are hardened and can be driven into concrete or block. You need a heavy hammer and it's a bit of a job, but for a few shelves might be the way to go. Absolutely wear eye protection, or better yet a face shield. You would just drive the nails through the 2x6 into the wall.

I'm not quite following you.

Are your shelves the free standing type and you want to fasten the uprights to the vertical 2x6's ?

When you use Tapcons to hold up 2x material..... you need to predrill the 2x with a hole just larger then the Tapcon. You may need to use a hammer drill to drill thru stucco over block.

Tapcons take a little getting used to. Depending on the hardness of the material they can be temperamental.

Do you know how thick the stucco is ?
Expansion anchors would be a good choice but they are depth dependent.

You use a hammer drill with that drill bit, not a standard drill. And yeah, the 3/16 screws kinda suck and will spin if you aren't real careful. The 1/4 x 2 3/4" will be better about grabbing... they have a little more thread.

Thanks for the replies guys. I'll see if I can borrow or rent a hammer drill. I'll keep trying to use the tapcons I may just have to use a larger diameter now.

PJmax I'm trying to attach vertical 2x6's to the wall of the garage and then build shelves off of them. I'll just buy the right angles for shelving and screw boards to it.

I agree with sleeper on the 1/4" Tapcons. Be sure to use the supplied bit and pre-drill your 2x6's.
You don't want the threads of the screw to catch on the wood or the wood won't be drawn up tight to the stucco/block.

The ones with hex heads will often drive easier, less slipping.
