Spring Pin, M4x10 CLEARANCE

These little pins slid right into place on my lathe's tailstock, which was a relief after wrestling with other brands. The 4mm diameter fit the hole perfectly with no binding.

I was slightly worried the clearance fit would be too loose, but it holds securely in my indexer’s detent without any wobble. Perfect size for those tiny 4mm holes on the lathe.

Fits snugly in a 4mm hole, which is what I was hoping for, though the “CLEARANCE” part made me wonder if it’d be loose—it’s not. Used it to pin a small gear on my lathe and it held fine. A bit shorter than I’d have liked for my setup, but that’s on me for not measuring twice.
