The 8.5 mm diameter fit perfectly into my lathe's handwheel assembly, and the partially threaded design made installation straightforward. Solidly built, this replacement feels sturdier than the original part it's replacing.

Bought this to replace a stripped bolt on my bench mill and the 53.5 mm unthreaded section fits the handwheel perfectly—no wobble at all. Threads engaged smoothly right out of the bag, which I wasn't expecting for a replacement part.

Wasn't sure the 8.5 mm nominal diameter would clear the bore on my mill, but it fit perfectly. The partially threaded design holds the handwheel securely without needing extra washers. Exactly what I needed to replace the original.
