Customer Reviews (4.8 / 5 · 5 reviews)

Ella K. ★★★★★

The 3mm diameter fits perfectly into my mini lathe’s linkage, and the 40mm length was exactly what I needed to replace the old one. Solid, sturdy build—no bending when I torqued it in.

Violet I. ★★★★★

Ordered this to replace a worn pin in my bench top machinery, and the 40mm length fit exactly where the old one sat. The 3mm diameter feels solid and snug once tapped in, no wobble or play at all. Glad I grabbed this instead of improvising with a bolt.

John ★★★★★

The 3mm diameter slid right into the lever shaft on my drill press with zero wobble, and the 40mm length gives just enough grip without needing extra washers. It's held up through a dozen cuts so far and feels solid.
