Core Material: High-strength cold-heading carbon steel or alloy steel is selected to provide good tensile strength and fatigue resistance.
Precision Manufacturing: Multi-station cold heading is used for integrated forming, combined with high-precision CNC turning to maintain accurate thread profiles and smooth engagement.

Extended-Length Structure: The elongated nut body is suitable for installation positions requiring a specific thread engagement depth.
Bulge Acorn Seat: The Bulge Acorn structure provides a larger contact area and is designed to match compatible wheel seat configurations.
Closed-End Design: Covers the exposed end of the wheel stud, helping reduce direct contact between the threads and dust, moisture, and road contaminants.

Customizable Specifications: Thread size, overall length, seat style, and surface finish can be customized according to specific application requirements.
Modified & Performance Vehicles: Suitable for vehicles equipped with deep-dish wheels, wider wheel spacers, or customized aluminum alloy wheels.
Off-Road & SUV Applications: Designed for demanding off-road driving and muddy or complex road conditions, with the closed-end structure helping protect the threaded area from harsh environmental exposure.
