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.
Another style of 1/4-28 nuts. This style is steel, with a rust resistant cadmium coating. I have found with a slight polish, these have a look close to stainless steel. These nuts are self locking, take a 3/8” wrench, and offer a built in washer with a diameter of .440 and an overall height of .323 inches. Excellent for any tight spaces. If you don’t need the locking feature, simply run a tap through the nut before using. Limited quantity.
