Bad Boy Mower 013-8043-00 – 5/16-18 Hex Nuts Zinc

The Bad Boy Mower 013-8043-00 – 5/16-18 Hex Nuts Zinc is a genuine OEM replacement fastener designed to keep your mower’s components securely fastened and performing as intended. Built to Bad Boy’s factory standards, this nut features a 5/16-18 thread pattern that provides consistent engagement with bolts and studs used across multiple mower assemblies.

The zinc-plated finish delivers superior protection against rust and corrosion, making it ideal for use in demanding outdoor environments where exposure to moisture, vibration, and debris is unavoidable. Each nut is engineered for reliable clamping force, preventing hardware loosening that can lead to wear or safety issues over time. Whether you’re servicing the mower deck, engine brackets, or frame components, this fastener maintains a strong, uniform hold.

Generic substitutes often lack the precise threading or plating quality that OEM parts guarantee. This Bad Boy Mower hex nut fits perfectly without cross-threading, reducing installation time and ensuring long-term stability. Using genuine hardware helps preserve the structural integrity of your mower while minimizing vibration-related damage to adjoining parts.

Homeowners and professionals alike trust Bad Boy OEM fasteners to maintain reliability across mowing seasons. At BadBoyMowerParts.com, we carry the full selection of bolts, nuts, washers, and related hardware along with blades, belts, and filters. With free shipping on orders over $100, keeping essential hardware like the 013-8043-00 on hand is simple and cost-effective for every maintenance routine.
