Review on 4-Pack MATCHFIT Dovetail Track Nut Hardware Set by Erik Barela

The Matchfit system has an attractive design. I really like using it as a spoiler on my CNC. However, these particular devices do not work very well. They are designed so that a screw can be mounted from above, which is often desirable. The plastic is soft and bends easily when tightened. If you try to tighten it further, the threaded brass insert will pull out. The bottom line is that when using them you can't tighten them enough to keep them stationary in the horizontal plane - they also don't work relative to the road. Make your own out of beech or maple. Cut, drill and thread - very easy. They hold up much better.
