Dome Cap Nut

Dome Cap Nut is a closed-end fastening nut designed to cover exposed bolt threads and provide a clean, smooth, and finished appearance. Also known as a cap nut, acorn nut, or domed cap nut, it features a rounded dome-shaped end that helps protect external threads from dust, contact damage, and accidental scratching.

Dome Cap Nut is commonly used in machinery, furniture, automotive, construction, handrails, railings, metal fabrication, equipment assembly, and general industrial applications where both fastening performance and appearance are important. The closed dome design helps improve safety by covering sharp or protruding thread ends, making it suitable for visible assemblies and areas where users may come into contact with the fastener.
