A cap nut — also known as an acorn nut — is a type of fastener with a domed top that fully covers the exposed end of a bolt or threaded rod.
Its design serves both functional and aesthetic purposes: it prevents accidental injuries from sharp thread ends, protects threads from damage or corrosion, and provides a smooth, finished look.
This particular cap nut is made from high-grade stainless steel, offering exceptional rust resistance and durability for both indoor and outdoor use.
The internal machine-cut threads ensure a secure and precise fit with corresponding bolts.
Cap nuts are widely used in automotive trim, machinery covers, furniture, playground equipment, and architectural fixtures where safety and appearance are important.
