Stainless steel (SS) and mild steel (MS) dome nuts, also known as acorn nuts or cap nuts, are specialized fasteners used to cover and protect threaded studs or bolts. Here are the typical details associated with these nuts:


  • Stainless Steel: Stainless steel dome nuts are manufactured from corrosion-resistant alloys such as SS304 or SS316. This ensures excellent durability and resistance to rust and corrosion, making them suitable for both indoor and outdoor applications.
  • Mild Steel: Mild steel dome nuts are made from low-carbon steel. While not as corrosion-resistant as stainless steel, they offer strength and affordability, making them suitable for various industrial and construction applications.


  • Dome nuts feature a domed or rounded cap on one end, which covers the exposed end of a threaded stud or bolt. This design provides a finished appearance and helps prevent snagging or injury from sharp edges.

Thread Type:

  • Dome nuts have internal threads that match the threads of the corresponding bolt or stud. The threads may be coarse or fine depending on the size and application requirements.

Size Range:

  • Dome nuts are available in various sizes to accommodate different bolt or stud diameters. Common sizes range from small diameters, such as #4 or M3, to larger sizes suitable for heavy-duty applications.


  • Dome nuts are primarily used for aesthetic purposes and to provide a finished appearance in applications where exposed fasteners are visible. They are commonly used in architectural, automotive, and decorative applications, as well as in machinery, furniture, and signage.


  • To install dome nuts, simply thread them onto the exposed end of a bolt or stud and tighten them by hand or using a suitable wrench or socket tool. The domed cap covers the threaded end of the bolt or stud, providing a smooth and finished appearance.

Security Features:

  • Some dome nuts are available with security features such as tamper-resistant designs or locking mechanisms. These features help prevent unauthorized removal of the nut and provide additional security in applications where tampering or vandalism is a concern.
