Review: How buying hardware should be - I used these when building a crib. They go in easy and look great. I was impressed by the quality and the attention to detail the sellers had. The bag had all the size information and drilling requirements. I used 24 of them and they each performed well. They even included an allen wrench. I have plenty of them, but it is nice to keep everything in the same spot. Now when I store them and use them later, the directions and the allen wrench will be in the same bag. Great job, this is how buying hardware should be.
Review: Works On Plastic - I make motorcycle rear racks from cutting boards. I use these inserts for additional strap anchors using eye bolts and also for camera mounts. Works great!

### ⭐⭐⭐⭐ Good value though quality isn’t perfect
*by J***. on March 8, 2025*

They work as expected and the quality is decent. Minus one star because the faces are a little rough looking and they have a tends to seat slightly crooked so that they do not sit perfectly flush with the surface of the wood.
