Flange Nut

Steel Nuts

This is a flange nut. Its 5/16"-18 thread size indicates it is designed for use with a bolt or stud of that specific diameter and thread pitch. Flange nuts are typically used to distribute the load over a larger area than a standard nut, reducing the chance of damage to the fastened part.

About nuts

Flange Nut is listed under Nuts — hex, nylon-insert, flange, wing, coupling and jam nuts. Nuts are internally threaded fasteners designed to mate with a corresponding externally threaded fastener, typically a bolt or screw, to create a secure joint. Their primary function is to resist axial loads and prevent loosening.
