4. Operating Instructions
These T-handle hex keys are designed for tightening and loosening fasteners with hexagonal sockets.
Using the Hex Keys:
- Select the Correct Size: Identify the correct metric hex key size that matches the fastener. Using an incorrect size can strip the fastener or damage the tool.
- Insert the Key: Insert the hex key fully into the fastener's socket. Ensure a snug fit to prevent slippage.
- Apply Torque: Grip the T-handle firmly. For tightening, turn clockwise. For loosening, turn counter-clockwise. The T-handle design allows for increased leverage and comfortable application of torque.
- Accessing Tight Spaces: The long arm design of these hex keys provides extended reach, making it easier to access fasteners in confined or recessed areas.
- Avoid Over-tightening: Apply appropriate force. Over-tightening can damage fasteners or the hex key.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your hex key set.
- Cleaning: After each use, wipe down the hex keys with a clean, dry cloth to remove any dirt, grease, or debris.
- Corrosion Protection: The black oxide finish provides some corrosion resistance. For prolonged storage or use in humid environments, a light coat of rust-preventative oil can be applied to the metal shafts.
- Storage: Always store the hex keys in their designated slots on the storage rack. This prevents loss, keeps them organized, and protects them from damage. Store in a dry environment.
- Inspection: Periodically inspect the hex keys for any signs of wear, bending, or damage to the tips. Discontinue use of any damaged tools to prevent injury or fastener damage.

6. Troubleshooting
Most issues with hex keys relate to improper use or selection.
- Hex Key Slipping:
- Ensure you are using the correct size hex key for the fastener.
- Make sure the hex key is fully seated in the fastener's socket.
- Check if the hex key tip is worn or rounded; replace if necessary.
- Fastener Stripping:
- This often occurs from using an incorrect size hex key or applying excessive torque.
- Ensure the hex key is fully engaged before applying force.
- Difficulty Loosening a Tight Fastener:
- Ensure a firm grip on the T-handle for maximum leverage.
- For extremely tight fasteners, consider using a penetrating oil or a different tool designed for higher torque applications, if appropriate for the fastener type.
