Customer Reviews (4.8 / 5 · 5 reviews)

Isabella A. ★★★★★

Machined the threads clean and they mesh perfectly with my existing dial. The 0.050" per rev is exactly right, and the 50-division dial makes it dead simple to track thousandths. Swapped it in, zero backlash issues so far.

Leo S. ★★★★★

Finally, a screw that matches the original threading exactly—installed it on my South Bend and the compound moves smoothly with no binding. The 0.050" per turn is a lifesaver for repeatable cuts.

Benjamin ★★★★★

The 20 TPI thread is spot-on—my compound moves exactly 0.050" per turn, so the math with my 50-division dial is effortless. Machined cleanly, no burrs, and it seated snugly without any wobble.
