Hex Jam Nuts, Zinc Plated, are designed for applications where a thinner, lower-profile nut is needed to lock or "jam" in place against another nut. The zinc plating provides moderate corrosion resistance and enhances durability. Typically used in situations where space is limited or in tandem with another nut to lock threads, these nuts are versatile in machinery, automotive, and construction applications. The hexagonal design facilitates easier installation and removal with standard tools.
