Over the years I have collected quite a selection of aircraft type hardware, especially 12 point nuts. Actually, more than one man will use in a lifetime. So I have decided to package these new, surplus nuts in 10 piece lots and offer them to the public.
I will start with the 3/8-24 nuts. This style is steel, with graphite? coating. I have found with a slight polish, these have a nice look to them. These nuts are self locking, take a 7/16” wrench, and offer a built in washer with a diameter of.626 and an overall height of .366 inches. Excellent for exhaust studs where space is at a premium. If the locking feature is not desired, a quick pass through these nuts with a tap will eliminate the locking threads.
