The pins slide together with a satisfyingly snug fit, making my jig assembly much more consistent. They're a solid upgrade from the generic hardware I was using before.

I needed something to precisely align a couple of transmission housings, and these pins slid in with zero slop and held tight. The alloy steel construction feels really sturdy compared to the cheaper ones I've used before, and having a full box of 100 means I won't run out mid-project.

Used these for aligning jig components and the consistency from pin to pin is spot on. The alloy steel feels solid and they slide in without any binding. Exactly what I needed for repeatable setups.
