      A:  Hello, I am sorry to hear you had a bad experience with this product. We have not had other complaints of this nature, however sometimes the heads can bend over, etc., if the hole is not drilled deep enough, reamed out enough, or drilled to the proper 5/16" size. If you did all these things and still had issues, please contact us to remedy the situation!

            Used these to fasten 3/4" foamboard to an interior block wall for an encapsulation project. They are a bit pricey, but they sure made the job much easier. Because of that, they were well worth their cost. I pre-drilled the recommended 5/16" pilot holes, and hammered these in with a rubber mallet. No issues.

            These are fantastic. Easy and fast to use I had no trouble at all. Much faster than using adhesive. each foam board took 3 minutes tops and no waiting for glue to dry or foamboard falling off the wall. You won’t be dissapointed
