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.
Only reason I didn’t give it five stars was because if you back to screw off a little bit and re-screw it it tears the rubber. Overall very satisfied
Cut great, low profile compared to 5/16 stitch screws. My guys love them.
