Bad Boy Mower 013-5202-00 – 3/8 Nylock Flange Nut

The Bad Boy Mower 013-5202-00 – 3/8 Nylock Flange Nut is a genuine OEM replacement fastener engineered to provide superior vibration resistance and long-lasting durability in demanding mower applications. Featuring an integrated nylon insert and flange base, this nut combines locking security with even load distribution for optimal fastening performance.

Constructed from high-strength steel, the 013-5202-00 includes a corrosion-resistant coating that protects against rust and wear in outdoor environments. The nylon insert firmly grips the threads of mating bolts, preventing loosening caused by vibration or impact—ideal for mower decks, frames, and suspension mounts.

The built-in flange eliminates the need for separate washers, simplifying installation and ensuring a stable, uniform connection surface. Designed to Bad Boy’s exact specifications, this Nylock flange nut maintains consistent torque and secure clamping force throughout extended mower operation.

Aftermarket versions may lack precise thread tolerance or use lower-grade nylon that deteriorates quickly under heat and vibration. The Bad Boy OEM 013-5202-00 Nylock Flange Nut ensures the same dependable fit, strength, and vibration resistance found in original factory-installed hardware.

At BadBoyMowerParts.com, we stock the complete selection of OEM nuts, bolts, washers, and hardware kits made to Bad Boy’s factory standards.
