SS304 316 stainless steel hexagon dome cap nut

Cap nuts are a common type of fastener, also known as cap nuts or cap nuts. Its appearance resembles a hat, hence its name. Cap nuts are usually made of metal materials, such as steel or stainless steel, which have excellent corrosion resistance and strength.
The design feature of cap nuts is that there is a cover (or cap) at the top that can be rotated by hand or tool to tighten or loosen the threads. Cap nuts typically have internal threads and are used in conjunction with bolts or screws. By rotating the nut, the bolt or screw can be fixed in the desired position, thereby achieving the fastening and connection of the parts.
