What Customers Are Saying
Customers report mixed results with these threaded inserts. Many describe the metal as too soft and prone to cracking or stripping during installation, particularly in hardwoods, with some finding the material non-magnetic and brittle. However, a substantial group confirms the inserts work well in soft woods, particle board, and MDF when pre-drilled correctly or combined with epoxy. Success depends heavily on application type and installation method. While some praise smooth threads and functionality, others cite poor value and lack of clear installation guidance. Overall, reviewers find them suitable for specific soft-wood projects but unreliable for demanding applications.

Would RecommendEasy to use
Carefully check the size hole you drill.
Test you drill hole! There was no guidance on the size of hole the collar should be inserted into. The size I chose initially was just a tad tight and when I used the hex wrench to screw this collar into the wood the hex end cracked before it was fully screwed in. I used a reverse bit to backout the entire collar (and tossed it away). Next drilled the next larger size drill to enlarge the hole and it went on ok this time.

Wood inserts
Would RecommendThis is a soft metal and using a hex key I stripped 2 out of four, so I threaded in a 1/4 20 bolt and turned it in that way. That’s why I gave it a 4 rating. Other than that glitch, they work just as they should.

DON'T BUY THIS CHEAP GARBAGE
Would Not RecommendIt's the most worthless grade of steel imaginable, it tears to pieces at the slightest tension and ruins your project. It's a scam manufacturer that Lowes should stop buying from.

WEAK material
Would Not RecommendIt did the job ... barely. The material is SO weak! It's good that these came in a 4-pack because I broke 2 of them trying to screw them into the wood. You must oversize the hole so that it's not screwing in very much. Eventually, they did the job, but barely.

Works fine if you use your head.
Would RecommendYes, as others said, the 6mm drive on these will strip out pretty easily. However, there are other ways to set these inserts. When the first one went into the kiln dried Douglas fir, it stripped about half-way in. I didn't want to mangle it up trying to get it out, so plan B. I grabbed a two inch long 1/4-20 hex head bolt and a 1/4-20 nut. I installed the nut onto the bolt, then threaded the bolt into the insert. I then tightened the nut against the insert, used a 7/16 inch wrench on the bolt, a...
