Nut Flanged

Flanged nuts are available in a variety of sizes and styles, for example domed or self locking. Flanged nuts have a wide flange at one end which acts as an integral washer. This wider flanged end spreads the pressure of the nut over the part it is securing and helps prevent damage to that part. It also helps the nut to grip as it has a wider grip surface even if that surface is uneven. Flanged nuts are usually hexagonal and made of hardened steel which is often zinc coated.
