I own a condo in a high rise building (mid-1970s construction). The walls are 1/2" drywall, and I'm guessing the structure is steel (perhaps with concrete?).
The other day I was attempting to add some wall hooks (rather beefy, made of solid brass) to a wall in my entryway, but I could not get a drywall anchor to go deeper than 1/2" before hitting something impenetrable. I've been able to use drywall anchors on other walls in my apartment, so it appears that this wall may just be load bearing or perhaps have wires or pipe running through it. Because of that possibility, I don't particularly want to try using a masonry bit to drill farther to see if it is in fact concrete
So, I'm wondering if it's possible to hang these hooks somehow. Are there drywall anchors that are only 1/2" long? Other options?
