Thread ran smooth and clean into the tapped holes on my jig fixture, and the hex head held torque without stripping. Zinc coating looks even and should protect well in my shop environment.

Needed a full box for a few custom brackets, and these were exactly the right thread pitch and length. The partial thread let me get a good bite without bottoming out in blind holes. Snugged them down with a socket and they held torque perfectly.

Couldn't ask for a better fit on my jig assembly — the hex head grabs the socket perfectly and the partial threads make adjustments a breeze. Exactly what I needed for a solid, repeatable clamp.
