I needed a few hundred of these 5/16-18 machine screws for a shelving project, and the 2-1/2" length worked perfectly for the thicker wood I'm using. The slotted drive took a bit of getting used to, but they hold tight once seated.

The truss head sits nice and flush on my metal brackets, plus the slotted drive makes tightening with a standard screwdriver easy. These two-and-a-half-inch machine screws are exactly what I needed for assembling a workbench frame.
