Customer Reviews (4.6 / 5 · 5 reviews)

Penelope C. ★★★★★

Bought these for a small electronics enclosure job and the trivalent zinc finish is holding up nicely—no rust spots after a few humid weeks. The flat heads sit flush against the panel, which is exactly what I needed.

John J. ★★★★★

The Phillips drive bites well without stripping, and the trivalent zinc finish looks clean and professional. I used these to secure a metal enclosure panel and every screw threaded smoothly. Definitely a good buy for the quantity.

Hannah ★★★★★

Flat head sits flush in the panel holes I’m using them on, and the trivalent zinc finish hasn’t shown a hint of rust after a few weeks in a damp shop. The 5000-count box means I’ll probably be handing these out to friends for years.
