The Dayton Parts 13-3005R is a heavy-duty inner cap nut designed for stud-piloted dual steel wheel assemblies. As a critical component for "Budd-style" wheels, this nut secures the inner wheel to the hub while providing the external threads necessary to mount the outer wheel and cap nut. This Right-Hand (Clockwise) thread version is engineered for the passenger side of the vehicle, ensuring the rotational forces of travel keep the fasteners seated securely.
Clockwise (Right) Thread: Designed specifically for the passenger side of the vehicle to maintain torque integrity during operation.
Corrosion Resistant Finish: Coated in yellow zinc/dichromate to withstand harsh road conditions, chemicals, and moisture.
Grade 8 Strength: Manufactured from high-tensile carbon steel to meet the rigorous demands of commercial trucking and heavy-duty towing.
Standard Fitment: Features the industry-standard 13/16" square drive for easy installation with standard tire service tools.
