Customer Reviews (4.4 / 5 · 5 reviews)

Jason ★★★★★

I needed a bulk supply for a metal cabinet project, and the zinc coating on these screws is smooth and consistent across all 300 pieces. They thread cleanly into tapped holes without binding.

Emma ★★★★★

Used these for attaching steel panels to a frame, and the zinc plating kept them clean through a few rainy days outside. The 3-1/2" length gave just enough bite without poking through. Sturdy pan heads seated nicely with a Phillips bit, no stripping at all.

Isabella N. ★★★★★

Had to mount some heavy brackets and these pan head screws threaded into the nuts without any binding. The 3-1/2 inch length gave me plenty of grip through thick panels. Good quality pack.
