Worked perfect for my project. Inserted into 3/4 inch osb and very strong with no tear out

Do not work well in soft woods, as they have a tendency to pull out!

Built a custom table and needed to attach the top to the metal stand but wanted it to be easily removable. These mounts worked great. Plan on using them for all my projects when applicable.

Of all the inserts I’ve used so far, I like these the best. Seemingly solid build, easy to install. Per the instructions I pre-drilled with 3/8” for hardwood, used a countersink for the little flange at top, and installed with the pictured bolt/nut combo tool on an impact driver and a small amount of super glue. No breaks, no fuss, giddy up!

I purchased these for a project we are working on and they work perfectly. The quantity for the price is fantastic! They also included the hex wrench and detailed instructions on hole side and dimensions. I highly recommend these!

These inserts install easily and are sturdy. Not as tough as some of the more expensive ones on the market but still plenty strong for diy and residential furniture etc. Great value for the money. Just make sure to use the correct size drill bit and a dab of glue or epoxy to lock them into the wood.
