Emily H. ★★★★★ Oct 14, 2026

Was tired of doing mental math at the hand wheel, so the 0.050" per turn on these is a welcome change. Both screws dropped into the X and Y without any shimming drama, and the nuts fit snug with barely any backlash. Cuts feel more predictable now.

Carter ★★★★★ Oct 13, 2026

Swapping to these 20 TPI screws made dialing in cuts so much easier, since one turn now equals a clean 0.050". The X and Y nuts fit right on with no slop. Backlash is way down compared to the old screws.

Matthew Y. ★★★★☆ Sep 15, 2026

Installed these on my mini mill and the 0.050" per turn makes dialing in cuts way less tedious than the stock screws. Only gripe is the nut fit needed a little fiddling to run smooth, but once adjusted it's solid.
