Makes a solid connection so never have to be concerned about wood threads failing and at the right price.

These inserts are much better than any I have found so far. This insert actually screws itself into your project. The surface area and larger contact points (with Titebond) make an exceptional joinery. I have not ripped any of this type loose as I did in previous knurled, pressed , and glued inserts.
