Customer Reviews (4.8 / 5 · 5 reviews)

Joseph ★★★★★

I needed some long screws for a metal framing project, and these cut through the steel studs cleanly without any pilot hole. The zinc coating looks consistent and should resist rust well enough for indoor use.

Daniel N. ★★★★★

The flat head sits perfectly flush on my metal project, and the zinc plating seems like it'll resist rust well. These screws cut through mild steel without any pilot hole hassle.

Robert L. ★★★★★

I needed longer fasteners for a metal framing project, and these 4-1/2" screws drove in without stripping, even with the flat head and Phillips drive. The zinc coating seems solid so far, no rust after a few damp days in the garage.
