Flange nut

The key features of this flange nut design are:

• d: Diameter of the nut

• k: Height or thickness of the nut

• s: Width across the flats of the hexagonal nut head

• dc: Diameter of the threaded hole in the center of the nut

The distinguishing feature is the presence of the flange or collar beneath the hexagonal nut head, labeled as (k) in the drawing.

Flange nuts are designed with this additional flange or collar to provide a larger bearing surface area compared to a standard hex nut. This helps distribute the load more evenly and prevents the nut from pulling through the mounting surface.

Flange nuts are commonly used in applications where secure mounting and load distribution are important, such as in machinery, automotive, and construction hardware. The flange design helps prevent the nut from loosening or pulling through the material it is tightened against.
