Customer Reviews (4.6 / 5 · 5 reviews)

Hannah ★★★★★

I was drilling into 16-gauge steel and these self-drilling screws cut through clean without needing a pilot hole, saving me a ton of time on my metal roofing project.

Miles ★★★★★

The square drive bit grabbed firmly without stripping, even when I was working at an awkward angle overhead. Drilled straight through 16-gauge steel in one motion and the 410 stainless gives me confidence for outdoor exposure.

Samuel ★★★★★

Used a handful to attach a gutter bracket to a steel shed—drilled right in without any pilot hole. The 410 stainless is noticeably tougher on the driver bit than standard screws I've used before.
