A hex flange nut is a type of nut

A hex flange nut is a type of nut that has a flange on one end, in the shape of a hexagon, which helps distribute the load of a tightened fastener. The flange also acts as a washer, providing a bearing surface for the fastener to bear against. This can help prevent damage to the material being fastened, as well as making it easier to tighten the fastener. Hex flange nuts are often used in automotive and construction applications, as well as in any application where a high level of clamping force is needed. They are available in a variety of sizes and materials, including steel, stainless steel, and brass.
