Review: Worked like a CHAAAAAAARM! - Beautiful. Came with the alan wrench needed to drive it into the wood. Also came with the drill bit that's the perfect size for them. Just drill the hole, grab an insert and drive it in with the alan wrench. Couldn't be any more simple than that. Has a very strong connection when testing with the 1/4" -20 threaded bolts I purchased with them. I build custom furniture and I use these for the the parts that the customer has to assemble themselves. They just line up the pieces and screw together with an included alan wrench. This allows for smaller boxes and lower shipping costs. Not only do these work great, they look great - professional, even though the parts that use these aren't visible in the end. But to the customer putting the thing together, it looks good.
Review: Hex drive is perfect to get it in straight - I bought these after using some from the local hardware (4 of them cost the same as the pack of 80). What I love about these is the hex drive, it was easy to keep them straight as they screwed in. The store bought ones I compared them to were to be driven in with a big flathead screwdriver which kept slipping and wouldn't keep them going in at 90. I had to use a hammer to straighten them half way in. These without much effort were able to be driven straight in and keep everything a little less damaged and so very tight with a dab of epoxy that I used to keep them in for longevity. Not to mention for the same price I get way more than I needed to dream up more projects to use them on.
