John ★★★★★

Used these to secure some steel brackets for a workbench shelf, and the flat head sat flush just like I needed. The zinc plating gives them a clean look and seems like it'll hold up well against light moisture.

Timothy S. ★★★★★

I needed a solid machine screw for a metal panel project, and these 5/16-18 x 2-1/2" flat heads with the zinc plating threaded in perfectly without binding. The steel feels sturdy, and the slotted drive gives a positive grip with a standard screwdriver. Exactly what I was looking for.

Kevin ★★★★★

The slot on the flat head is cut clean, so a standard screwdriver seats properly without stripping. I used a handful to mount a steel panel to an enclosure and they threaded in tight with no wobble. Zinc coating looks even and should hold up fine where I've got them.
