Setup
The Performance Tool W30901 Nut Driver Set requires minimal setup. Upon receiving the product:
- Remove the nut drivers from their packaging.
- Inspect each nut driver for any signs of damage or manufacturing defects. Do not use damaged tools.
- Familiarize yourself with the different metric sizes (5mm to 12mm) to ensure quick selection during tasks.
- Store the nut drivers in a clean, dry place, preferably in a tool organizer or box to prevent loss and damage.
Operating Instructions
Follow these guidelines for effective and safe operation of your nut drivers:
- Select the Correct Size: Always choose the nut driver that precisely matches the size of the nut or bolt head. Using an incorrect size can strip the fastener or damage the tool.
- Ensure Proper Engagement: Place the nut driver squarely over the fastener, ensuring full engagement with all sides of the nut or bolt head.
- Apply Steady Pressure: Apply steady, firm pressure while turning the nut driver. Avoid sudden jerks or excessive force, which can lead to slippage or damage.
- Utilize Hollow Shafts: For fasteners with long threaded shafts, the hollow design of these nut drivers allows the shaft to pass through, enabling you to reach and turn nuts located deeper on the bolt.
- Tightening/Loosening: Turn clockwise to tighten and counter-clockwise to loosen. Always ensure the fastener is securely tightened but avoid over-tightening, which can cause damage.

Maintenance
Proper maintenance ensures the longevity and performance of your nut drivers:
- Cleaning: After each use, wipe down the nut drivers with a clean, dry cloth to remove dirt, grease, and debris. For stubborn grime, use a mild cleaner and ensure tools are completely dry before storage.
- Storage: Store the nut drivers in a dry environment to prevent rust and corrosion. Keep them organized in a toolbox or tool roll to protect them from impacts and prevent loss.
- Inspection: Periodically inspect the shafts and tips for any signs of wear, bending, or damage. Replace any damaged tools to maintain safety and effectiveness.
- Corrosion Protection: While chrome-plated for corrosion resistance, applying a light coat of rust preventative oil to the metal shafts can offer additional protection, especially in humid environments.
Troubleshooting
Most issues with nut drivers stem from improper use or selection. Here are common scenarios and solutions:
- Fastener Slipping: If the nut driver slips off the fastener, ensure you are using the correct size and that the tool is fully engaged. Apply firm, steady pressure.
- Stripped Fastener: A stripped fastener head usually indicates an incorrect tool size was used or excessive force was applied. In such cases, specialized tools may be required for removal.
- Difficulty Reaching Fastener: If a nut driver cannot reach a deeply recessed nut, verify that the hollow shaft is being utilized correctly. If the bolt is too long for the hollow shaft, consider alternative tools like deep sockets with an extension.
- Tool Damage: If a nut driver becomes bent or cracked, discontinue use immediately. Damaged tools can be unsafe and ineffective.
