Lucy ★★★★★

The cup point design made alignment much easier than standard set screws when I was securing a shaft collar. The black oxide finish seems durable and hasn't shown any wear after several adjustments. These felt precise and well-machined right out of the package.

Timothy ★★★★★

Installed these to secure a pulley on a motor shaft, and the hex socket fit my Allen wrench perfectly without any stripping. The cup point bit in firmly enough that the pulley hasn't budged under load.

John C. ★★★★★

The black oxide finish on these set screws didn't chip or flake at all when I torqued them down, which is more than I can say for cheaper packs I've tried. Cup point bit in nicely on the shaft and they're holding firm after a few weeks of vibration. Exactly the hardware I needed for the price.
