Scarlett ★★★★★

The 10-12.7-30 mm clearance fit slid right onto my ball screw with no shimming needed, and the clamp screws bit down tight without stripping. Runout is minimal, so my X-axis cuts come out cleaner than before.

William E. ★★★★★

Swapped this onto the Y-axis ball screw of my CNC mill and the fit was dead on, no wobble at all once tightened. The bore sizes matched the shaft and motor stubs without any shimming, which saved me a headache.

Charlotte I. ★★★★★

The 10-12.7-30 mm clearance fit snugged right onto my ball screw with no shimming, which was a relief after fighting the old one for an hour. Backlash on my X axis is basically gone now and the finish on my parts looks noticeably cleaner.
