One-Piece CLOSED END - BULGE WHEEL NUT
Closed-End Bulge Wheel Nut for Increased Contact Stability and Long-Term Protection
Product Intro
Our One-Piece Closed-End Bulge Wheel Nuts feature an enlarged seating surface that increases contact area and clamping stability, providing a secure fit for both OEM and aftermarket wheels. The closed-end design protects the stud threads from dirt, moisture, and corrosion, helping extend service life and maintain consistent tightening performance.Each nut is precision-formed through multi-stage cold forging to achieve superior strength and uniform material density. CNC machining ensures accurate threading, smooth installation, and consistent dimensional tolerances. These nuts are available in carbon steel or alloy steel, with optional heat treatment to enhance hardness and fatigue resistance.Surface finishes such as zinc, black zinc, nickel-chrome, and Dacromet deliver enhanced corrosion protection and long-term durability, making them suitable for a wide range of wheel applications and environmental conditions.
