Ava N. ★★★★★

The threads on this replacement lead screw match up perfectly with my lathe’s original setup, and the machining is noticeably cleaner than the old part. It’s a solid, direct-fit upgrade that took maybe 20 minutes to swap in.

Ava C. ★★★★★

Installed this on my SC4 and the threading matched perfectly, no filing or adjustments needed. The steel feels solid and it's noticeably quieter than the old one it replaced.

Robert K. ★★★★★

Finally got my lathe running smoothly again with this replacement lead screw. The 8.5x16 threading matched the old part perfectly, no filing or fiddling needed to fit. It feels solid on the bench, and my cuts are coming out way more precise than before.
