Cap Nuts

A nut with a smooth, and occasionally domed, top used to cap the end of a threaded fastener is commonly known as a cap nut. This type of nut serves several important functions, including preventing stripping or corrosion of the threaded end and providing a tidy and finished appearance. Cap nuts can also be referred to as low crown acorn nuts or crown nuts due to their resemblance to the shape of an acorn or crown. Cap nuts are particularly useful in applications where aesthetics are important, as they provide a clean and polished look to the exposed threaded end of a fastener. Additionally, by covering the threads, they help protect against corrosion and damage, prolonging the lifespan of the fastener and the assembly as a whole.
