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 3/8-24 nuts. This style is stainless steel, with a rust resistant (graphite based?) coating. I have found with a slight polish, these have a very nice look. These nuts are NOT self locking, take a ½” wrench, and offer a built in washer with a diameter of.675 and an overall height of .461 inches. Excellent for exhaust studs. Noet that the washer on these are a squared off design.
