Review on FastenMaster FMHLGM278 500 Heavy Duty Flathead 500 Count by John Hall

I used these to evenly fasten a strip of my new decking. It holds the wood in place and looks great in place of unsightly nail/screw holes. I also used a 5 1/2 to attach my railing post. The screws are very strong and the bits don't slip - they are designed for impact drills. It is necessary for outdoor projects. This is my third time using them and I will definitely continue.
