Ruby L. ★★★★★

I’ve been using these #4-40 x 3/16” screws for mounting small metal panels, and the flat undercut head sits flush without any wobble. The 18/8 stainless steel feels solid and hasn’t shown any rust after a few weeks in a slightly damp shop.

George C. ★★★★★

Finally, a bulk pack of #4-40 screws that actually holds up to tightening without stripping. The flat undercut head sits flush in my aluminum enclosure panels, and the 2000 count should last me through several more builds.

Adam ★★★★★

I’ve been using these #4-40 screws for securing enclosures, and the flat undercut head sits perfectly flush with the surface. The 18/8 stainless steel feels solid and hasn’t shown any corrosion after a few weeks.
