Setup and Installation
- Select the Correct Adapter: Identify the appropriate adapter based on the drive size of your tool (e.g., impact wrench, ratchet) and the drive size of the socket you intend to use. For example, use the 1/2" to 3/8" adapter if your tool has a 1/2" drive and your socket has a 3/8" drive.
- Attach to Tool: Insert the male square drive end of the adapter into the female square drive receiver of your tool. Ensure it is fully seated.
- Attach Socket: Place the desired socket onto the male square drive end of the adapter. The magnetic retention feature will help hold the socket securely in place.
- Verify Connection: Gently tug on the socket to ensure it is firmly attached to the adapter and the adapter is firmly attached to the tool before applying torque.

Operating Instructions
These adapters are designed for use with impact wrenches, ratchets, and torque wrenches. Always observe safety precautions relevant to your power tools.
- General Use: Once the adapter and socket are securely attached to your tool, proceed with your task as you would with a standard socket. The low-profile design allows access to restricted areas.
- Impact Tool Compatibility: These adapters are made from CR-MO steel, making them suitable for impact applications. However, always ensure the adapter's torque rating is appropriate for the task and tool being used.
- Magnetic Retention: The integrated magnets provide a strong hold, reducing the chance of sockets falling off during overhead work or in awkward positions.
Maintenance
Proper maintenance ensures the longevity and performance of your WORKPRO socket adapters.
- Cleaning: After each use, wipe the adapters clean with a dry cloth to remove dirt, grease, and debris. For stubborn grime, a mild solvent can be used, followed by thorough drying.
- Lubrication: Lightly oil the square drive ends periodically to prevent rust and ensure smooth attachment to tools and sockets.
- Storage: Store the adapters in a dry environment to prevent corrosion. The nested design allows for compact storage. Keep them away from strong magnetic fields if not in use, to avoid demagnetization over extended periods, though the magnets are designed for durability.
- Inspection: Regularly inspect adapters for signs of wear, cracks, or damage. Discontinue use if any damage is observed and replace the affected adapter.

Troubleshooting
If you encounter issues with your socket adapter set, consider the following:
- Socket Not Holding Securely:
- Ensure the socket is fully seated on the adapter.
- Check for debris or obstruction on the magnetic surface or inside the socket.
- Verify the magnet's strength. If significantly weakened, the adapter may need replacement.
- Adapter Stuck on Tool/Socket:
- Apply a small amount of penetrating oil if corrosion is suspected.
- Gently tap the connection point with a rubber mallet to loosen. Avoid excessive force.
- Adapter Damage (Cracks, Bending):
- Discontinue use immediately. Damaged adapters can be dangerous and lead to further tool or fastener damage.
- Ensure you are not exceeding the adapter's intended torque capacity, especially with high-power impact tools.
