Customer Reviews (4.6 / 5 · 5 reviews)

Timothy ★★★★★

The fillister heads on these screws hold a wrench nicely, and the stainless steel feels solid for outdoor enclosures. I've used about 200 so far from the 1400-pack without a single stripped slot or burr.

Ruby C. ★★★★★

Needed a full box of these small machine screws for a panel project, and the fillister head gives a cleaner look than flat heads for the same job. The 18/8 stainless feels solid and they thread smoothly into pre-tapped holes without any binding.

Daniel R. ★★★★★

Finally found the right screws for mounting a small control panel, and the 18/8 stainless steel feels solid. The fillister head sits flush without catching on anything, and having 1400 in the package means I won't run out mid-project.
