Spring Pin, M2.5x5

These little M2.5x5 pins press in perfectly for the small jig I was building on my mini mill. I've had trouble keeping parts aligned with standard hardware, but this spring pin holds tight without any wobble.

Was a bit skeptical about the fit on my mini lathe, but the 2.5mm diameter seated perfectly in the pre-drilled hole without any wobble. The 5mm length is just right for a firm hold on the tool post, and it tapped in cleanly with a light hammer.

The 2.5x5mm size is exactly what I needed for my bench top jig, and it snapped into place with a satisfying click. This pin feels solid for such a small fastener.
