초록 ▼

A one-piece flag nut having a flag portion protruding perpendicularly to the axis of a nut portion thereof such that during installation, as the flag nut rotates, the flag portion catches on any nearby structure and acts as a wrench during the installation process. The one-piece flag nut is formed by an extrusion process, and preferably formed to have ribs provided on the flag portion thereof which provide strength to the flag nut. The outer edges of the flag portion are preferably rolled to prevent the flag portion from being hung up on the structure during the installation process, thus preventing the flag nut from being properly seated.
