The Dayton Parts 13-3016L is a heavy-duty flanged cap nut designed for stud-piloted wheel systems. This fastener is engineered to match the fit and performance of original equipment, providing a secure, high-torque mount for commercial vehicle wheels. Featuring an integrated flange and a Left-Hand (Counterclockwise) thread, it is specifically designed for the driver's side of the vehicle to ensure the nut remains tight under operational stress.
Integrated Flange: The built-in flange acts as a washer, distributing clamping force evenly to prevent wheel damage and ensure a secure seat.
Left-Hand Thread: Engineered for the left (driver) side of the vehicle to prevent fastener "walk" during rotation.
Direct Replacement: Designed to meet or exceed OEM standards for fit, function, and durability.
Durable Carbon Steel: Constructed from high-grade materials to withstand the high-torque requirements of the heavy-duty trucking industry.
Yellow Zinc/Silver Finish: Provides a protective barrier against rust, road salt, and environmental corrosion.
