Review on Stainless Phillips Screw Bolt Dropper by Josh Zuvers

Purchased to complete garage shelving installation. When I screwed the first one in (after drilling the pilot holes) it snapped almost 3/4" into place! I've never had this before so I figured it was just an accident. The next one worked fine but the next 2 broke too! When I put 12 screws in, 6 accidentally broke off like branches. I've never experienced anything like this with wood screws of this size. I can only assume that they are of below average quality. I certainly do not recommend them, unless you only use them for light work on very soft woods (and maybe just hand tightening) Needless to say, VERY disappointed.
