Two-Piece CLOSED END - BULGE WHEEL NUT
Closed-End Bulge Wheel Nut for Increased Seating Contact and Enhanced Clamping Stability
Product Intro
Our Two-Piece Closed-End Bulge Wheel Nuts are engineered for enhanced durability and secure fitment. The closed-end design prevents contamination and protects the wheel stud threads, extending service life. The bulge seat increases the seating contact area, providing stronger clamping force and consistent torque retention across various wheel types.Each nut is manufactured through multi-stage cold forging to achieve high structural strength and uniform material density. CNC machining ensures accurate threading and precise dimensional tolerances. Material options include carbon steel and alloy steel, with optional heat treatment available to improve hardness and fatigue resistance.Surface finishes such as zinc, black zinc, nickel-chrome, Dacromet, or custom coatings offer corrosion protection suitable for both OEM and aftermarket applications.
