The shoulder on this replacement screw is machined more precisely than the original, so the quill advances with zero wobble. Drilling centered holes finally feels reliable on my mini lathe.

The threads engage smoothly every time I slide the quill forward for drilling. Fits my mini lathe without any slop, and the precise movement makes tailstock work feel way more controlled than before.

The quill on my mini lathe advances with barely any play now, and the screw's precise threading makes drilling depth control feel much more reliable. It slots in perfectly with the existing tailstock assembly, so I didn't have to fiddle with any extra parts.
