Joseph ★★★★★

The zinc plating looks clean and uniform across all 2000 pieces, so none of them arrived rusted or scratched. They seat perfectly in the phillips driver without stripping, and that round head sits flush on my steel panel.

Stella N. ★★★★★

Picked up a pack of these #4-40 x 9/16" screws for a project, and the zinc plating gives them a nice, consistent shine. They seat perfectly into my metal enclosure with a phillips driver, no stripping or binding.

Evelyn ★★★★★

I used these screws to mount a small electrical panel and the Phillips drive caught perfectly without stripping. The zinc finish looks clean and the 2000-count box will last me years.
