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.

Keep fasteners tightly in place with these self-locking nuts. They resist loosening due to vibration or temperature changes. Their threads have an irregular shape to lock onto the standard threads of a mated fastener.
