Leo ★★★★★

Installing a replacement nameplate on an old machine, these stainless screws matched perfectly and the cone point seated flush in the countersink. No stripped heads or rust worries.

Evelyn W. ★★★★★

For a small electronics project, I needed a large quantity of consistent, corrosion-resistant screws, and these 18-8 stainless steel pan heads delivered perfectly. The cone point really helps start them cleanly in tight pre-tapped holes.

Nicholas ★★★★★

I've been using these 4-40 screws for a metalworking jig and the pan head sits perfectly flush in the countersunk holes. The stainless steel hasn't shown any signs of rust after a few weeks in a humid shop.
