Daniel F. ★★★★★

The M4x20 pin fit perfectly into my bench top machinist setup with no wobble or extra play. The threaded portion grabbed cleanly on the first try without cross-threading. Exactly what I needed as a replacement.

Lucy ★★★★★

Was a little unsure about the sizing at first, but the M4x20 threads seated perfectly into my bench setup without any play. The steel feels solid and the machining is clean, so it's holding up exactly as a replacement pin should.

Ava ★★★★★

Fits perfectly on my mini lathe as a replacement for the original part. The M4x20 threading was spot on, and it’s machined cleanly with no burrs. Saved me from having to order a whole new assembly.
