Cannot screw into drywall, looks like this

Just noticed the screws will not go into the drywall... opened a plug and took a picture. What is this?

any ideas. Screw and drill will not make a dent.

Left side of that hole looks like sheetrock.

If screws wont go in ..... it must be some kind of cement.

Cement board maybe.

In looking at some of your other pics......it looks like poured concrete.

Try a Tapcon drill bit and its associated screw. Test to see if the screw holds. If it does just use Tapcons.

Is this possibly a stem wall in a basement? Often they are rocked over to make a flat wall. Usually they have furring strips, but they can be over framed and the sheetrock glued to the concrete wall.

Looks like it could be Rock-Lath.....an early drywall equivalent from the 50's or 60's

Usually had a thick coat of hard plaster on top.....stud finders have a tough time with it.

If you only need a couple of holes then it can be drilled with a regular drill bit.

You can see the box opening was made with a key-hole or jig saw.

That mud ring is not being held on by much......the mounting wings aren't gripping anything.

I was going to say exactly what Halton mentioned. It looks like a layer of drywall-type stuff (usually with 1/2" holes throughout it, after which a plaster is coated on top. The last one I took down, I could have sworn that the plaster was actually cement because of what a PITA it was to deal with.

Use a masonry bit and anchors (chosen based on what you're actually hanging). Or just a masonry bit to get through and screw into the studs.

Thanks guys,

Are their anchor bits that are long enough for this.

I was able to screw stuff into the studs, but i missed one stud and went straight into the plaster/drywall. I predrilled the holes first though. It feels like its holding pretty strong. I prefer not to go outside of the studs though.

You can use toggle or 1" reach hollow wall anchors etc.....there's a variety of choices.

Depends on what it is your are hanging and how heavy it is.
