Customer Reviews (4.8 / 5 · 5 reviews)

Ellie ★★★★★

The 410 stainless steel is exactly what I needed for outdoor framing—no rust worries after a week of rain. These #12s drive straight into the metal studs without pre-drilling, and the hex head sits flush enough that my socket barely slipped once.

George ★★★★★

The hex washer head really grabs the surface without sinking in—perfect for metal roofing. Drives straight through 16-gauge steel without pre-drilling. Already ordered a second pack for the next job.

Joshua ★★★★★

Put these #12s through a real test fastening metal roofing panels, and the hex washer head seated perfectly without any stripping. The 410 stainless held up well against the weather here on the coast too.
