Dome Nuts

(Protective & Aesthetic Cap Nuts for Clean and Safe Fastening Ends)

Neo Fasteners supplies high-quality Dome Nuts, also known as Cap Nuts, engineered to provide a safe, smooth, and aesthetic finish to exposed bolt threads. These nuts feature a closed-end domed top that not only covers the threaded bolt end but also adds a sleek, finished appearance—making them ideal for furniture, automotive, architectural, and public installations.

Available in a range of materials and surface finishes, our Dome Nuts offer both functional protection and decorative appeal.

🔩 Product Overview:

Dome Nuts are internally threaded nuts with a rounded, closed top. This dome conceals and protects the protruding bolt or stud threads from dirt, damage, corrosion, and accidental contact—reducing the risk of injury or material wear. In addition to safety, they provide an elegant finish in visible or exposed applications.

Neo Fasteners offers Dome Nuts in metric and imperial sizes, with both standard and high-dome profiles to suit your design or engineering needs.
