Customer Reviews (4.4 / 5 · 5 reviews)

Jacob ★★★★★

Fits perfectly on the lead screw for the 80-tooth gear, and the keyway alignment was spot-on. The metal feels sturdy enough to handle the torque without any wobble. Glad I found this exact size.

Violet ★★★★★

The keyway lines up perfectly with the shaft, so it slipped right into place without any filing or fiddling. It’s a solid, snug fit that keeps the 80 tooth gear locked down just where it should be.

Emma ★★★★★

That 8mm length is exactly what I needed to stop the lead screw from walking sideways. The keyway lined up perfectly with the gear so no extra filing was required.
