Customer Reviews (4.8 / 5 · 5 reviews)

Sebastian ★★★★★

Got this for my ER-16 spindle setup and the M22*1.5 internal threads engaged smoothly with no binding. The 1.1 inch outer diameter gives me plenty of grip for tightening.

Julian ★★★★★

Fits perfectly on my ER-16 spindle and holds the collet securely without any wobble. The 1.1 inch outer diameter is exactly as described, making it easy to tighten by hand.

Zoe Z. ★★★★★

The M22*1.5 threads on this nut are cut clean and it seats onto the spindle without any wobble, even with a collet installed. Outside diameter of 28mm gives plenty of grip for tightening with a wrench.
