Emily ★★★★★

I needed some tiny set screws for a repair, and these #4-40s threaded in smooth and held tight without stripping. The hex socket drive made it easy to get them snug in a cramped spot.

Claire ★★★★★

These set screws have a really nice, sharp cup point that bites into the shaft securely. The hex socket drive made them easy to install in a tight spot on my mill.

Harper ★★★★☆

The hex socket drive made installing these into a tight spot much easier than I expected. Cup point grips well even on the smallest components. Only wish the packaging had dividers to keep sizes separate.
