Good product, but better quality control is required
Although these were exactly what I was needing, I had to throw 8 of the 40 away. They were bent (warped) out of the box. Better quality control is required. Was still able to complete my project, however.

Great screws!
Worked very well for my project and worked well with my drill. Did not strip out the heads.

Worked as needed
These are just what I needed to repair a broken La-Z-Boy recliner chair frame. (The frames are guaranteed for life but I don’t have the original receipt after 25 years) Some glue and these screws and I’m back in business.
