Hex Cap Nuts are six-sided, closed-end nuts designed to cover and protect the exposed threads of a bolt or screw. These nuts not only enhance the visual appearance of the fastening assembly but also help prevent damage and corrosion to the threaded section. Commonly known as hex blind nuts, cap nuts, or hexagon cover nuts, they can be paired with various types of bolts for both functional and aesthetic purposes.

They are manufactured in both metric and imperial sizes, adhering to thread profiles such as UNC, UNF, UN, and ISO metric standards. Hex cap nuts are available in a wide selection of materials, grades, and conform to multiple ASTM specifications to meet diverse application requirements.
