I have decided to package these new, surplus nuts in 10 piece lots and offer them for sale.
This is another variation of 5/16-24 nuts. This style is steel, with a rust resistant cadmium coating. These nuts are self locking, take a 7/16” wrench, and offer a built in washer with a diameter of.531 and an overall height of .350 inches. Excellent for carbs, valve covers, etc. Limited quantity.
