Review on 🔩 High-Quality 1/4"-20 T-Nuts (100pc) by Bolt Dropper – Pronged Tee Nut for Wood, Rock Climbing Holds, Cabinetry by Ryan Huhn

Very handy. I've found that to make the rod really sturdy since 1/4" isn't a thick measurement you can also add a second rod to the back of the rod. To do this I cut the pins off the back t-nut so I could just screw them in. Of course a nut and washer will do for this, but with a modified T-nut I can secure the back with a flat fastener. Even make it flat with the surface if I lightly screw the back with a Drill out so the second t-nut sits flush.
