Penelope ★★★★★

The phillips head on these #4-40 screws is nicely machined, so my driver didn't slip even when torquing them into a tight metal bracket. For the price, getting a full 5000-pack of trivalent zinc fasteners was a no-brainer for my workshop stock.

Evelyn ★★★★★

Got a whole box of these for a small electronics enclosure job, and the trivalent zinc finish looks clean and didn't scratch during assembly. The pan head sits flush enough for tight spaces, and with 5,000 pieces I won't be reordering any time soon.

Scarlett ★★★★★

The Phillips drive on these #4-40 screws bit perfectly without any stripping, which was a relief for a delicate metal panel job. The 5000-pack will last me through many projects.
