Setup
The WORKPRO W022005 Hex Key Set requires minimal setup. The hex keys are pre-assembled within the folding handle. To prepare for use:
- Identify the Required Size: Locate the hex key with the correct SAE size for your fastener. The sizes are typically marked on the individual keys or the housing.
- Extend the Hex Key: Gently pull the desired hex key outwards from the housing until it locks into an extended position. The folding mechanism is designed for easy access to each key.

Operating Instructions
This hex key set is designed for manual operation to tighten or loosen hex drive fasteners. Follow these steps for effective use:
- Select the Correct Size: Ensure the selected hex key precisely fits the fastener head. Using an incorrect size can damage both the key and the fastener.
- Insert the Key: Insert the hex key fully into the fastener head. Ensure it is seated securely to prevent slipping.
- Apply Torque: Hold the comfort-grip handle firmly. Rotate the hex key clockwise to tighten the fastener or counter-clockwise to loosen it. Apply steady, controlled pressure. The ergonomic handle is designed to provide a good grip and facilitate hand torque.
- Retract After Use: Once the task is complete, fold the hex key back into the housing for compact storage.

Maintenance
Proper maintenance ensures the longevity and performance of your WORKPRO Hex Key Set:
- Cleaning: After each use, wipe the hex keys and housing with a clean, dry cloth to remove dirt, grease, or debris. For stubborn grime, a mild detergent solution can be used, followed by thorough drying.
- Lubrication: Periodically apply a light coat of rust-preventative oil to the metal hex keys, especially if stored in humid environments. This helps prevent corrosion.
- Storage: Store the hex key set in a dry place, away from excessive moisture and corrosive chemicals. The folding design allows for compact storage in a toolbox or drawer.
- Inspection: Regularly inspect the hex keys for any signs of wear, bending, or damage. Replace the set if any keys are compromised, as damaged tools can lead to injury or fastener damage.
Troubleshooting
If you encounter issues while using your hex key set, consider the following:
- Hex Key Not Fitting: Ensure you are using the correct SAE size for the fastener. Double-check the fastener type; it may require a different tool (e.g., Torx, Phillips).
- Difficulty Turning Fastener: The fastener may be overtightened, corroded, or cross-threaded. Apply penetrating oil if corrosion is suspected. For very tight fasteners, ensure you have a firm grip and apply steady, increasing torque. Avoid sudden jerking motions.
- Stripping Fastener Head: This usually occurs if the hex key is not fully seated, is the wrong size, or excessive force is applied incorrectly. Always ensure a snug fit and apply smooth, consistent torque. If a fastener head is already stripped, specialized extraction tools may be required.
- Loose Keys in Housing: If the keys feel loose within the housing, check the pivot screws. While generally not user-adjustable, excessive looseness might indicate wear.
