The locking nut seats perfectly against this base, and the screw passes through with zero wobble once tightened. Took maybe ten minutes to swap out on the mill and everything lines up true.

Installed this on my mill last weekend and the fit with the locking nut was spot on, no slop at all. Made a noticeable difference in z-axis rigidity during light cuts.

The threads on this base mate with the feed screw perfectly, and the locking nut seats flush with zero wobble once cinched down. I swapped out my old setup for this and the Z-axis travel feels far more rigid now. It's a solid piece of casting that does exactly what it's supposed to do.
