Serrated Hex Nut Set for Spartan Mower Deck Hardware - 1/2-13 Thread SKU: 32128-49X3

Loose bolts in mower deck hardware create dangerous blade imbalances, compromised cutting performance, and potential safety hazards. This set of three serrated hex nuts secures critical fasteners against the constant vibration that causes standard hardware to work loose during operation.

Why Serrated Nuts Matter

• Serrated face bites into mounting surfaces to resist vibration loosening
• Durable steel construction with corrosion-resistant plating for outdoor use
• 1/2-13 thread size matches critical mower deck components
• Genuine Spartan Parts built for commercial-grade reliability

When your mower deck hardware starts working loose, these serrated nuts provide the grip standard hardware can't deliver. Install them with matching bolts and torque to specification for vibration-resistant fastening that stays tight. S&H Parts stocks genuine hardware solutions for equipment that needs to work every time.
