Hex Machine Screw Nuts

Hex Machine Screw Nuts are similar to a finished hex nut but they come in smaller sizes. They are typically used with machine screws. We carry them in many materials such as steel, stainless steel, brass, silicon bronze, and plastic.

We carry them in both in inch and metric. We start at 0 and go to all the way up to 3/8. We also carry the small pattern series as well which offers smaller width across the flats and corners than regular machine screw nuts.

China Aluminum Screws, Inc. carries them in the square pattern as well. Instead of six sides as the hex machine screw nut, they come with four sides. This allows a greater bearing surface for wrenching.
