Attach 2x4 to block wall in garage

I was thinking about mounting some 2x4s in the garage so hang tools etc on.
The garage walls are made of concrete block, what would be the recommended way and screws to hang the 2x4s?

tapcons or screws and anchors

tapcons are easier because you can drill through the 2x and into the block and then drive the screw .

anchors are cheaper but you have to align the hole in the 2x with the anchor .

Note that you will want to mount into mortar joints versus the block itself especially if the block has hollow sections such as cinder blocks.

But if you must mount into the block, make sure you are drilling into a hollow, and use wing molly bolts. Make your first drill into the wall with a tapcon drill, so if you do hit a solid space, you can use a tapcon, but should it be hollow, a larger drill can be used to enlarge it for a wing.

I believe the correct term is toggle bolt not molly bolt.Molly bolts are an anchor designed mainly for drywall although a large enough one might work in a hollow of a cinder block...could be tough to get to expand since it must grip the wall surface.Mollys do not have "wings" though that would be a toggle bolt which would also be more appropriate for a cinder block.Drill hole large enough for folded wing to pass through then it opens on the other side.

BTW the term "Molly" is from the original producers/inventors of the molly bolt anchor....Molly Industries.That's why many copies of the anchor do not actually call it a molly bolt they call it a drywall anchor.

Thanks for the replies! I was thinking about drilling into the mortar.
What's a tapcon drill? I have a black and decker rechargable drill and some drill bits, will this get the job done?

Tapcons themselves are heavy screws designed to be screwed directly into a drilled hole in masonry with no anchor.These screws require an exact drilled hole and there are specific bits for the purpose.Beyond those specific bits the alternative would be a masonry bit of the proper size.Since most tapcons take odd sized bits such as 5/32 or 7/32 it's hard to find ordinary masonry bits of the proper size.Generally where the tapcons are located or on any packaging of them will be a notation of the right bit size.Note that regular high speed bit will NOT work for masonry.Also sometimes tapcons are called masonry screws.

Rather than buying the tapcon bits , bosh has a superior bit for about the same money

just be sure to get the right size

spdavid, thanks for the heads up. I forgot to use the word "or" between wing and molly, since the wing toggle will grab from behind and there are certain mollies that have deep enough clear shank to clear nominal block wall thickness, but you have to look hard for them. Most have 1/2" setbacks, but there are some with a 1" or better shaft.

If you go that way check lots of the tapcons come with the drill bit for them. Got some like that at Home de pot
