An insert nut is a nut that is either hammered or screwed into material, depending on the fastener type. Used in furniture applications, the nut receives a machine screw or connecting bolt to fasten pieces together. Available in various fastener types depending on application.
I purchased these to fix some chair legs. They are soft and brittle and the head broke when using a screwdriver with very little force. I was able to get a few in with some finesse and they cracked internally. I do not reccomend purchasing
I am using these inserts as part of a built-in desk to allow the legs to be removed if needed to clean/change the room carpeting. These were inserted into the underside which was poplar board. I drilled the holes wide enough for the barrels to fit but leaving room for the threads to bite into the wood. Three out of four of these inserts cracked when I tried to screw them into their holes: this happened quickly and I was barely putting any force on them. It seems that these inserts cannot take the force to get them to screw in, unless you drill out so much material that the corkscrew part has very little to bite into the wood. Worse still is that where these cracked, they left burrs and other material that made screwing in the bolts very difficult to do. I am very disappointed in these and certainly do not recommend these.
The few of these that I bought had issues when I screwed in 1/4 - 20 eyebolts. I had to run the bolts in several times before it was ok. Also I purchased several more at a big competetors store. Different brand, still solid brass, but about half the price AND they were smooth operating from the beginning.

I don't like these. It's difficult to find a screwdriver big enough to fit where it needs to screw in. Because of that, the little rim on the top broke off on a few different occasions. Now looking for the ones that screw in with the hex key.
The reviewer who said the screwdriver slots break easily is using it wrong. There are no screwdriver slots. The slots are meant to help cut the wood as they are driven in. use a 1/4" all thread and two nuts to secure the insert and drive it in that way.
