Dome nuts, sometimes called acorn nuts or cap nuts, are a versatile fastener used for aesthetic and practical reasons wherever a bare screw thread is a concern. Unlike using standard nut fixings, a dome nut completely covers the end of a screw. As such, it can be used in lieu of, or on top of, fastening nuts. These domed nuts come in a variety of materials including nylon, plastic and stainless steel can be used to cap threaded bars or make sure a surface is snag-free.
