ナット、Z軸ロック、HiTorque 大型ベンチミル

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.

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.

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.
