These are Grade 2 rated nuts. These are the "full" size nuts, not the "thin" nuts you see in other auctions. These full size taller nuts do allow for higher torque values because of the larger thread surface area. Zinc finish is not as perfect or bright as chrome, but still a decent finish.

THIS AUCTION IS FOR QUANTITY OF 10. I have different/larger quantities listed in my other auctions. The larger quantities have bigger discounts. Please email me with any questions.
