John I. ★★★★★

Put the ring on my 20mm shaft with just my thumb pressure and it snapped right into the groove—held the assembly together solid. No burs or sharp edges, which I appreciate on small bench work.

Robert T. ★★★★★

Worked perfectly for securing a gear on my lathe's 20 mm shaft. The fit was snug and precise right out of the packet, no filing needed.

Michael J. ★★★★★

Bought these for a bench project and they slipped right onto the 20mm shaft without any forcing. The fit is snug enough that I didn't worry about them popping off during assembly, and the small size made them easy to handle with pliers. Exactly what I needed for the job.
