VIGRUE 81PCS 1/4"-20 x 15mm/20mm/25mm Furniture Screw in Nut Threaded Inserts Nuts for Wood Bolt Fastener Connector Hex Socket Drive Flanged Assortment Set with Hex Spanner

Very intelligently designed. Definitely use the longest insert nut that your project will accept

I've used these for several wood projects and they work great.

Bought this to use for attaching a frame to my son's train table, used a little wood glue on the threads and was very happy with the results. Would have paid a little more if they threw in a drill bit for simplicity.

Very sturdy the inserts use an Allen wrench for install and will not strip out like others that just use a screwdriver slot.

I use these to fix a cheap dining table set. The legs kept coming loose and the seats eventually came loose as well. I bored holes in the seat bottoms, and into the legs, added these and beefier hardware. It did the job very well.

This is a great set of threads for installing in your woodworking projects. As a woodturner, I find them particularly convenient for handles. The more strength you need, the longer piece you select. For permanent installation, I put a drop of CA glue in the side of the wood hole before installing the threaded insert. Then the insert never backs out of the wood while I use the 1/4-20 threads.

Works great and a great priceScrews in easily with the wrench included

I liked the convenience of the container. Using them for sofa tables that I'm building
