Customer Reviews (4.6 / 5 · 5 reviews)

Hannah ★★★★★

Finally got the Z-axis to stop drifting mid-cut; this nut threaded perfectly onto the feed screw and locks tight with just a quarter turn. My only minor gripe is that it didn’t come with a wrench, but the machining is dead-on—exactly what I needed.

Owen ★★★★★

Finally got around to swapping this onto my mill, and the fit on the Z-axis screw was perfect—no slop at all. It locks down solidly now, which makes precise depth cuts way easier to repeat.

Carter ★★★★★

The threads on this nut matched the feed screw perfectly the first try, so no fiddling or filing to get it seated. Once torqued down, it holds the Z-axis rock solid with zero drift, even after a full afternoon of heavy cuts. Wish I'd swapped the original out months ago.
