Christopher ★★★★★

I was skeptical about finding a retainer nut with the right thread pitch for my old grinder, but this one threaded on smoothly and held fast right away. The 3/8-24 threading is exactly what I needed, and the 1 3/4-inch diameter covers the arbor hole perfectly. It feels solidly built for the abrasive

Jason ★★★★★

Perfect fit on my surface grinder’s spindle—the 1 3/4-inch diameter seats exactly as it should, and the 3/8-24 threads engaged smoothly without any wobble. Feels solid enough for daily use.

Hannah E. ★★★★★

The threads cut clean and it seats flush on the arbor without any wobble, so the fit is exactly as spec’d. The 1 3/4 diameter gives plenty of grip for tightening by hand, even with gloves on.
