Scarlett N. ★★★★★

These are perfect for a marine railing repair I just finished; the 304 stainless held up fine after a saltwater spray test. The #12-24 threads bit cleanly into the pre-tapped holes, and the 400-count box means I've got plenty left for future projects.

Sebastian T. ★★★★★

Used a handful of these to mount some outdoor electrical covers since they're 304 stainless, and they're holding up great after a few weeks of rain. The Phillips drive cuts down on cam-out with a power drill.

Henry ★★★★★

I’ve been using these screws for a few outdoor projects, and the 18/8 stainless steel has held up well against rain without any rust. The Phillips drive seated easily with my drill, saving time on assembly.
