### ⭐⭐⭐⭐⭐ Great T-nuts

### ⭐⭐⭐⭐⭐ Good quality
*by D***O on May 5, 2025*

As described and significantly cheaper than my local hardware store.

### ⭐⭐⭐⭐⭐ Some helpful information for CNC router users
*by A***R on November 10, 2018*

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.
