I was worried about alignment issues, but this screw retainer locks everything in place smoothly and the threads engaged perfectly on my first try.

Fits like a glove on the mini mill and the feed screw stays rock-solidly aligned through a full afternoon of cutting, which is exactly what I needed after the original let things drift. Even the mounting holes lined up perfectly with no filing required.

Mine came slightly greasy out of the bag, but once wiped down it seated perfectly and the Y-axis feed screw hasn’t budged a millimeter since. It’s a simple part, but the fit is snug enough that I don’t worry about alignment mid-cut anymore.
