Rock Bugle Laminating Drywall Screws Review

Interesting product but they really don't have enough wide/deep threads to pull or hold boards together (which is what drywall lamination screws are for). I ended up carefully feeding them through the two layers of board I had laminated (slightly sanding the hole if not very carefully) and then removed them one at a time, dipping the end in PVA glue and carefully replacing them. Hole.
