1/4"-20 T-Nut (100 Pack), Zinc-Plated Steel Corriosion Resistant, 5/16" Barrel Length, 4-Pronged Tee Nut for Wood, Rock Climbing Holds and Cabinetry by Bolt Dropper

Used half a package attaching plywood to utility trailer sides, no defective nuts in the lot.

Our big box store is always out of these and when they do have them they are like $2.50 a PAIR! Outrageous! These were a great value by the 100 bulk pack and they arrived in 2 days. I will be buying more of them on Amazon. Well made and they work great. A+++

I bought some of these in the 1/4 x 20 size to make a custom spoil board for my Shopbot desktop router. I really wanted some without the barbs on the back, but I figured at $10, I'd take a chance. They worked out exactly as I hoped they would. Since these were on the back of the spoil board to provide hold down locations from the top, I took a pair of pliers and easily broke the barbs off as the MDF I use would have never survived those barbs. I then drilled a 3/8 hole in a piece of mild steel and used it as an anvil to flatten the rim of the Tee Nut out. For those who are interested, I used a .800" x .075 counter bore on the back with a central hole through the spill board of .310" diameter. This required tapping them in with a mallet and I used a flat punch to make sure they were seated into the counterbore so they would not contact the machine bed. It's a little more work than buying the brad hole version, but they are insanely cheap. When this spoil board is used up, I intend to just use a 1/4 x 20 bolt to drive them out from the front and reuse them. A great product at a great price. BTW, none had tight or distorted threads, all were free running! My only complaint is I wish they made these with just a round rim for the same price so you didn't have to remove the barbs.

Used these tees nut in my shop and garage for multiple project
