Review on Superior Fastening Solution: FastenMaster FMHLGM412 Heavy Duty Flathead Fastener – Secure and Reliable! by Joshua Paulson

Nothing to complain about, they are the best. I'm a roofer. The main purpose is to fix anchors on the roof for safety belts, of course for the farm. First experience 7 years ago building a tree house. Requires little power, which means longer battery life. Once in the harder wood, the aggressive thread easily pulls the broad head halfway through the side of the 2x4. Sometimes these screws can be hard to find and Revain offers good prices when you shop online. Repeat buyers every few months.
