Customer Reviews (4.8 / 5 · 5 reviews)

George ★★★★★

Punched right through a thin steel bracket without stripping, and the zinc coating kept them rust-free even after a humid week in my garage. Perfect fit for the enclosure I was assembling.

Natalie J. ★★★★★

Used a handful of these to secure a metal junction box to a steel beam—the pan head sat flush perfectly. The zinc plating looks clean and none of the threads felt gritty. A solid hundred-count bag for the price.

Elizabeth G. ★★★★★

Finally got around to mounting some sheet metal brackets and these little screws fit perfectly with zero stripping. The zinc plating looks uniform and clean, no rough edges to snag on. Exactly what I needed for a clean assembly.
