Yes there is, one kind is called Tap-Con they come with a drill bit sized just right for them, just drill the hole and screw them in. they hold very well. Ace, Lowes, Home Depot all have them

Self drilling? Must be a REALLY good quality screw! Let us know if you find them.

I used the Tap-Cons in the wall that splits the garage from the shop. Works very well, and strong!!

yah like said, you need to drill a hole with a masonary bit, and then srew the screw in. Id think if theres a self tapping kind they would be too much money.

Yeah, but like taping metal, it has to be the correct size tap drill for the concrete or brick.
If it's not, you could split the concrete or brick with the screw and that's a pain if it's a critical situation.
Best to use the matching drill bit with the screws. I used a Tap Con setup that held the drill in the chuck and the driver went over it when you needed to screw it in. Quick and easy.

Tap cons work Ok without a pilot in real green concrete. but you better have a good impact driver to get them in. Much easier with a pilot hole first.
Think about it, a self drilling screw needs to drill the same speed as it screws in. No way you can drill into concrete with just a couple revolutions. That's why self drilling is only used on sheet metal, and not solid.
That said, the tapcons do a good job. Get a hammer drill, and it is pretty painless.

I drill 1/4 steel (3/8 to 1/2 isn't out of the question)all the time with Teck screws, they make teck screws with different length drill tips, they are also fine thread

Tap-Cons work great...but you have to drill the dang hole first. I don't have a hammer drill, but even w/o it's not a huge deal. They hold great in cinderblock.

Tap-cons can be a real ******* some times. One trick we use at work is drill the hole quite a bit deeper than the length of the screw and back the bit in and out several times to clear out debris. That way the threads of the screw don't bind up on all the lose **** , and any grit created by installing the screw falls into the cavity below. Walrus is right about the Tek brand of self tappers for steel. They are the **** for screwing into metal. On the larger diameter and length ones , going into thicker metal it is sometimes beneficial to drill a pilot hole but not always required.

The difference is there isn't any additional "anchor", like a plastic anchor or a wedge. The screw holds itself to the concrete.

Not to hijack the thread, but a job I was on I didn't have tapcon's long enough to secure a 2x4 down. Job Super says.... just drill the hole with the tapcon bit and use a 3" or 3.5" spike with a length of small diameter wire and drive it in. I found out that if you intend to remove said spike, good luck. Holds like hell !

One other little bit of advice. If you can go with 1/4" or larger, do it. I just snapped off a 3/16" tapcon under a non-removable threshold. I have no idea how I'm going to get it out.

Another option for attaching lumber to masonry is use 2 or 3 galvanized 16 penny nails and drive them all in the same hole. They will wedge themselves tight holding extremely well.
