برغي، دليل جلبة المغزل، ماكينة طحن صغيرة Micro Mill

The pin on this screw does exactly what it should—my spindle sleeve hasn't budged a single degree since I torqued it in. Machining cuts feel steadier now, which is a relief for the price of a small part like this.

Installed this in my Micro Mill to replace a worn original, and the pin fit snugly into the guide slot, stopping the sleeve from rotating as intended. The threading matched perfectly with the existing parts—no filing or adjustments needed. Solid replacement that got my spindle working smoothly again

The pin design works exactly as described, so my spindle sleeve finally stops rotating during cuts. It seated cleanly into the mill and took maybe ten minutes to swap out. Solid fix for a frustrating issue.
