Jason ★★★★★

After struggling with backlash on my mini mill for months, these 20 TPI feed screws finally give me the precision I need—each rotation advances exactly 0.050", which makes dialing in cuts so much more predictable. Installation was straightforward and the difference in feel is night and day.

Hazel ★★★★★

Putting these in took an afternoon, but the 0.050" advance per rotation makes dialing in cuts feel far more precise than the stock setup. The 20 TPI threads mesh smoothly with the hand wheels, and I noticed zero backlash after snugging everything down. Definitely worth the upgrade for any mini mill

Michael V. ★★★★★

I swapped these into my HF mini mill and the 0.050" per rotation makes dialing in cuts way more predictable. The threads engage smoothly without any binding.
