These screws drove well into the steel purlins

I needed additional screws for my roof, and the building mfg wanted a small fortune. These were far less expensive, drove better and were an almost perfect match for my gray sheeting. The building mfg sent 2" screws when the design documents called out 1.25 inch screws. I hated those screws as they were very difficult to drive.
