Ellie I. ★★★★★

The truss head on these machine screws gives them a nice low profile, and they seated flush in my metal brackets without any issues. The 2-1/2 inch length was perfect for the thickness I was working with, and two hundred pieces covered my whole project.

Adam H. ★★★★★

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.

Timothy J. ★★★★★

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.
