Lily ★★★★★

Replaced the old worn gib on my SC4 lathe and it tightened up the half nut slop nicely. The 63 mm length was exactly what I needed, and it seated perfectly without any filing or sanding to get it to fit.

Ellie ★★★★★

The fit was perfect—this gib slid right into place on my SC4 without any adjustment needed. Machining feel is noticeably smoother now with the lead screw half nut.

Isabella O. ★★★★★

Installed it on my SC4 and the threads meshed smoothly right away — no filing or adjustments needed. The 63 mm length matched the original part exactly, so swapping it out took maybe ten minutes.
