Ruby ★★★★★

The threads on this sleeve matched perfectly with my existing lead screw, making the swap a quick 15-minute job. It's holding alignment well during heavy turning passes.

Ella ★★★★★

Let me tell you, the threads on this connecting sleeve are cut so precisely that the lead screw spins without the slightest wobble now. Installation was a straightforward swap on my bench lathe, and it's already made a noticeable difference in the machine's smoothness.

William ★★★★★

The sleeve fits perfectly onto my SC4's lead screw—no slop or play at all. Took about ten minutes to swap out, and now the threading operation runs much smoother. Exactly what I needed to keep the old lathe working reliably.
