The GRACO 18B340 KEY is a square drive key measuring 1/4" square by 1.875" in length. It is typically made from hardened steel and is used as a mechanical interface for driving or securing components within GRACO equipment, such as the GrindLazer concrete grinders and similar machinery.

Key Features:

• Square drive key
• 1/4" SQ X 1.875"
• Hardened steel (assumed, not explicitly stated)
• Compatible with GRACO GrindLazer models and other equipment requiring a 1/4" square drive key
• Precise fit for secure component engagement
• Durable construction for repeated use
• Standardized size for easy replacement

Applications:
Used as a drive key in GRACO GrindLazer concrete grinders and other machinery requiring a 1/4" square drive interface for assembly, maintenance, or adjustment operations.

Installation Notes:

• Using a genuine GRACO key ensures proper fit, safety, and reliability of the equipment, reducing the risk of component failure or damage.
• Ensure the key is fully seated in the mating component before applying torque.
• Inspect the key for wear or deformation before each use.
• Replace the key if it shows signs of excessive wear or damage.
• Regularly check the key for signs of wear or damage.
• Keep spare keys on hand for quick replacement.
• Store keys in a clean, dry environment to prevent corrosion.
