Does anyone remember what those mushroom-type nuts were that were used with threaded rods when putting pay phones on cinder block walls? We have an installation of large flat-screen TVs on block walls in classrooms. The customer insists on threaded rods through the wall to the classroom on the other side. We nicknamed them 'mushrooms', where the rod threaded into a hub on them and the view on the other side was just a domed dimple, similar to the head of a carriage bolt. Any idea of what they were called?

They looked like this, but instead of an attached rod, there was a threaded socket to accept the rod coming through the wall so that only the dimple showed: PICTURE

John, I think you're onto it. I found this using the term 'weld nut' in a search and came up with this, which is very close. The ones I'm seeking are larger and have more of a smooth domed finish, like the head of a carriage bolt. Thanks for the information. WELD NUT PICTURE

If your talking about 8" CMU, just use a carriage bolt, you can easily find 12" lengths at home depot. Make sure you drill from the opposite side of the TV mount, just in case you blast a hole the size of a barn door, upon exit; the mount will cover this up. Once you thread your nut, you'll also have to plan to cut any excess bolt length off with a 4" cut-off wheel..

Ed,
We always called them Cap Nuts, and they looked like Skip's picture.
