What do you call these?

[Tom Veatch]

I give up! I've bought them before, but now, I'm drawing a blank.

The are about 1" long, 1/2" wide and have a 1/4-20 threaded hole in the center. Essentially, they are the nut equivalent of a "t-bolt".

I need a couple of dozen and am having trouble finding them. It'd help if I could remember what they are called. I've tried "t-nut" (nope), "sliding t-nut" (almost), and everything else I can think of.

If anyone knows their name, I'd surely appreciate an introduction - better yet, a link to a supplier would receive a hearty welcome.

McMaster Carr calls them bridge weld nuts

Dave/Richard/Scott - Thanks a load guys! One of those links will surely provide what I need.

I'd swear I did a search on "T-slot nut", but, if so, it didn't hit on the Lee Valley site. Most of what I found were those big chunks of metal you use in the T-Slots on milling machine tables.

We use them by the thousands installing "Unistrut" so we called them "strut nuts"
