What Are Acorn Nuts?

Acorn nuts, also known as cap nuts or crown hex nuts, are a type of nut that features a domed cap on one end. This cap covers the exposed end of a bolt or screw, providing a finished appearance and protecting the threads from damage. The name “acorn nut” comes from the nut’s resemblance to the shape of an acorn.

As a professional fastener supplier, Xinchi Fastener Company is glad to introduce the key features of cap nuts.

what does an acorn look like?

Domed cap: Cap nuts have a rounded or domed cap on one end, which is often smooth and aesthetically pleasing. The cap may also have knurling or other patterns for enhanced grip.

Hexagonal base: The base of the cap nut is hexagonal (six-sided), allowing it to be tightened or loosened with a wrench or socket.

Decorative and protective: The primary purpose of cap nuts is decorative, providing a clean and finished appearance to the fastening point. Additionally, the cap protects the threads from dirt, debris, and potential damage.

Non-threaded interior: Unlike regular nuts, cap nuts do not have internal threads. Instead, they are typically used with bolts or screws that have matching threads to create a secure fastening.

Various materials: Cap nuts are made from a variety of materials, including steel, stainless steel, brass, and other alloys, depending on the application’s requirements.

Cap nuts are commonly used in applications where the exposed end of a bolt or screw requires a neat and polished look. They are often found in furniture assembly, railing systems, light fixtures, and other decorative or exposed fastening points. It’s important to ensure that the cap nut is sized to fit the corresponding bolt or screw correctly for a secure and reliable fastening.
