5/16-18 Flanged Lock Nut with Zinc Coating 10-Pack SKU: 104-8300X10

Loose hardware on mower decks, frames, and linkages creates dangerous vibration and compromises cut quality. These flanged lock nuts solve the problem with their integral flange that distributes clamping force and resists loosening during high-vibration operation.

Why This Hardware Matters

• Built-in flange eliminates the need for separate washers while spreading load evenly
• Zinc coating provides corrosion resistance for outdoor exposure and moisture
• Vibration-resistant design maintains secure connections during demanding mowing operations
• 10-pack quantity ensures you have spares on hand for maintenance and repairs

These flanged lock nuts are the reliable fastening solution your mower's critical components need. Thread onto clean bolts and torque evenly—the flange should sit flat for maximum holding power.
