Lug-Nut

A man wearing a random raider armor and carrying a random weapon (hunting rifle, sawed-off shotgun, or assault rifle) who appears if the player loots the Naughty Nightwear as part of the unmarked quest Grady's Package. Upon taking the Naughty Nightwear, Lug-Nut will demand that you give it to him. If the player refuses to give it to him, he will become hostile and attack you, or you can just intimidate him with a high enough speech skill. He can be enslaved with a Mesmetron.

If you successfully scare him off with Speech, he'll hang around the Marigold Metro Station tunnels, and may be attacked and eaten by the resident Giant Fire Ants. If he spawns with an assault rifle, he does a fairly decent job of killing any ants that respawn near where-ever he's wandering. However, if he appears with a hunting rifle or sawed-off shotgun, he'll promptly be turned into ant food if he ever runs into any of them.

Lug-nut is also mentioned by Sierra Petrovita when asked more about Ronald Laren. She will start talking about how tough Ronald Laren is and during so will mention Lug-nut and two other raiders, the two unknown raiders are killed by Ronald Laren, who then punches Lug-nut one in the face. Lug-Nut probably only survived because Ronald was using his signature weapons, The Kneecapper, which only has a two-shot capacity before reloading. Lug-Nut most likely made a run for it as Ronald was reloading.
