Customer Reviews (4.8 / 5 · 5 reviews)

Miles ★★★★★

The key slot for the m4x16 fitting was machined precisely, so my new lead screw seated perfectly without any wobble. Installation took about 20 minutes, and now my lathe's threading is smooth and accurate again.

David A. ★★★★★

I needed a replacement for my worn-out lead screw, and this drive shaft fit perfectly with the M4x16 key slot already machined in place. The threads are clean and consistent, which made installation straightforward on my lathe.

Joseph ★★★★★

The fit and finish on the drive shaft is precise—the keyway accepts the M4x16 key without any play. Installed it on my SC4 and the lead screw engagement feels much more solid than the old part.
