Cap Nut

The key features shown in the image are:

• m: The overall diameter of the cap nut

• d: The diameter of the internal threaded hole

• H: The height or thickness of the cap nut

• A/F: The width across the flats of the hexagonal cap nut

A cap nut is a type of nut that has a domed or rounded top, enclosing the threaded portion. This design provides a smooth, finished appearance compared to a standard hex nut.

Cap nuts are commonly used in applications where aesthetics are important, such as furniture, machinery, and consumer products. The rounded cap helps protect against snagging or injury from exposed corners.

The specific dimensions provided in the drawing, including the overall diameter (m), threaded hole size (d), height (H), and width across flats (A/F), would allow this particular cap nut to be properly manufactured and specified for the intended use.

Cap nuts are available in a variety of materials, such as metal, plastic, or a combination, depending on the performance and appearance requirements of the application.
