6. Operating Instructions
Follow these steps for safe and effective operation of your hex key:
- Select the Correct Size: Ensure the 1/2" hex key matches the size of the hexagonal socket screw you intend to work with. Using an incorrect size can strip the fastener or damage the tool.
- Insert Fully: Insert the hex key fully into the fastener's socket. Ensure it is seated completely to prevent cam-out and damage.
- Apply Torque:
- For maximum leverage and torque, use the long arm of the hex key.
- For applications in confined spaces or when less torque is required, use the short arm.
- Turn: Rotate the hex key clockwise to tighten or counter-clockwise to loosen the fastener. Apply steady, even pressure.
- Avoid Over-tightening: Do not apply excessive force beyond what is necessary, as this can damage the fastener or the tool.
Safety Precaution: Always wear appropriate personal protective equipment (PPE), such as safety glasses, when using hand tools. Do not use the hex key as a pry bar or chisel.
7. Maintenance
Proper maintenance will extend the life of your Proto Hex Key:
- Cleaning: After each use, wipe the hex key clean with a dry cloth to remove dirt, grease, or debris.
- Rust Prevention: Although rust-resistant, storing the tool in a dry environment is recommended. For long-term storage, a light coat of rust-preventative oil can be applied.
- Inspection: Periodically inspect the hex key for signs of wear, bending, or damage. Replace the tool if it shows significant wear or damage to prevent injury or fastener stripping.
- Storage: Store the hex key in a tool box or on a tool rack to protect it from impacts and moisture.
8. Troubleshooting
| Problem | Possible Cause | Solution |
