Thomas ★★★★★

The 40mm length was exactly what I needed to secure some metal brackets on a workbench. These pan heads sit flush and the combination drive made installation with either a Phillips or flathead bit convenient.

Mia Y. ★★★★★

Zinc plating on these machine screws is nice and even—no flaking when I tightened them with a hex key. They bite into the metal enclosure threads cleanly and hold fast, which is exactly what I needed for mounting a panel.

Emma ★★★★★

Combination drive saved me when my bit slipped—flathead worked just fine in a pinch. The zinc finish is smooth and uniform across all 180 pieces, and the pan heads sit flush on my metal enclosure panels without any wobble.
