Spring Pin, M3x16

Slid into the bore cleanly for alignment work, no burs or tight spots at the 16mm length. It's held firm under the bench press, exactly what this setup needed.

The 3x16mm size was exactly what I needed for a tight spot on my drill press jig, and the spring tension feels solid when tapped in place.

I needed a compact option for a jig alignment and these 16mm pins clicked right into place without any forcing. The steel feels solid enough to hold repeated pressure without bending.
