The GRACO 113981 is a high tensile lock nut designed for use in GRACO equipment. It is a fastening component intended to secure parts within GRACO sprayers and related machinery, ensuring reliable assembly and resistance to loosening under vibration or load. The material is not explicitly stated, but high tensile nuts are typically made from hardened steel for strength and durability.

Key Features:

• Lock nut
• High tensile (likely hardened steel)
• Designed for use in GRACO sprayers and equipment (specific models may vary)
• High tensile strength for secure fastening
• Resistant to loosening under vibration
• Compact size for integration into equipment assemblies

Applications:
Used as a fastening component in GRACO sprayers and related equipment to ensure secure assembly and reliable operation.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety within equipment assemblies.
• Ensure the nut is tightened to the manufacturer’s recommended torque specifications.
• Inspect for wear or damage before installation.
• Use appropriate tools to avoid over-tightening or stripping threads.
• Regularly check for loosening or wear during routine maintenance.
• Replace with genuine GRACO parts if damaged or worn.
