About Acorn Nuts

Shield threads from damage and provide a smooth, finished look by covering the ends of fasteners with these domed head nuts. Acorn nuts are typically put on fasteners that are in plain view or have protruding ends.

The tall crown has more threads than a standard nut for a more secure hold and better vibration resistance.
