Bolt Dropper T-Nut Wood Insert, Carbon Steel, Black Zinc Finish, 4-Prong 1/4"-20x5/16, Flush Surface Fasteners for Wood, Particle, or Composite Materials Workpiece, Set of 100

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+++

As described and significantly cheaper than my local hardware store.

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.

Good product, overall. Don't expect them to hammer in flush with the wood surface - not designed for that. They hold pretty well, but I epoxied min in for added push/pull strength, which necessitated removing migrated glue from the threads with a tap. Otherwise, worked well with 10-24 threaded rod. Also, unless you're installing them with a press, they won't necessarily hammer in with the bore perfectly perpendicular to the wood surface (tilted a little), owing to the different densities of the wood grain. And stay in as much as possible from the edge of the wood, or the nearest tooth may split out when the wood grain spins the nut as it's hammered in.

Worked great

They do the job as they should

I used these to build an indoor rock climbing wall. I was having a hard time finding the number I needed locally. The quality was good. The quantity count was accurate. The overall structure of them is sound and the threads were clean and worked well. Will be ordering more in the future.

Excellent low cost solution for levelling shop furniture.

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

Nice product.

This product is well built, threads were well taped and had absolutely no issues with it at all… this product is well worth the purchase

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

Good
