Dome nuts, also known as cap nuts, are designed to cover exposed bolt threads while delivering a clean and finished appearance. Their closed-end construction prevents moisture, dirt, and debris from entering the threads, helping to reduce corrosion and extend service life. In addition to enhancing safety by covering sharp bolt ends, they add a neat and professional look to assemblies. Widely used in furniture, architectural, and automotive applications, dome nuts are suitable for both indoor and outdoor use, including heavy-duty environments where durability and appearance matter.
