How buying hardware should be

I used these when building a crib. They go in easy and look great. I was impressed by the quality and the attention to detail the sellers had. The bag had all the size information and drilling requirements. I used 24 of them and they each performed well. They even included an allen wrench. I have plenty of them, but it is nice to keep everything in the same spot. Now when I store them and use them later, the directions and the allen wrench will be in the same bag. Great job, this is how buying hardware should be.

Work good easy to use

These are great. Been using them in various projects from MDF to Hardwood. Easy to use get a good drill set to go with it.

Good value though quality isn’t perfect

They work as expected and the quality is decent. Minus one star because the faces are a little rough looking and they have a tends to seat slightly crooked so that they do not sit perfectly flush with the surface of the wood.

Got the best

Exactly what I wanted and needed to complete my job. Thanks for your service.

Should have bought long ago.

I finally broke down and used these on the most recent table I made. I had resisted buying because I thought screwing legs directly into the wood was fine. No, this is much, much more stable.

Well made and easy to install

I used three 1-3/4 x 4" wide red oak cleats on the bottom side of my 2" thick oak work bench top instead of c-channel to help keep the top flat. I slotted the holes in the cleats to allow for wood expansion. I attached the cleats to the underside of the top using these 1 inch (20mm) long steel threaded inserts. I used about 25 inserts for this project. I drilled the 3/8" pilot holes using a shop made drill guide and a veritas 3/8" brad point drill bit. After drilling, I chamfered the holes with a counter sink. I drove the inserts in with a harbor freight T-handle allen driver. The inserts went in fairly tight but did not feel like they were too tight. They all drove in with out damage to the inserts or the driver. The 1/4-20 bolts used to secure the cleats fit nicely without any problems. I was able to remove a few inserts and reuse them in a different location with no problems. Best inserts I've ever used. Highly recommed.
