3. Operating Instructions

These sockets are designed for use with 3/8" drive impact tools. Always select the correct size socket for the fastener to prevent damage to both the fastener and the tool.

Using Sockets:

1. Select Correct Size: Match the socket size (SAE or Metric, standard or deep) to the fastener. The laser-etched and stamped markings aid in quick selection.
2. Attach to Impact Tool: Securely attach the chosen socket to your 3/8" drive impact wrench or ratchet. Ensure the detent pin engages properly.
3. Position on Fastener: Place the socket squarely onto the fastener. For hard-to-reach areas, utilize the 3" or 6" extensions. The universal joint allows for angled access.
4. Apply Force: Operate your impact tool according to its manufacturer's instructions. The off-corner loading design of these sockets helps distribute force across the fastener flats, reducing the chance of rounding.

Off-Corner Loading Design:

The innovative off-corner loading design of these sockets applies torque to the sides of the fastener head, rather than the corners. This design minimizes stress on the fastener corners, significantly reducing the risk of rounding and allowing for more effective torque transfer.

4. Maintenance

Proper maintenance ensures the longevity and performance of your GEARWRENCH socket set.

Cleaning and Storage:

• After each use, wipe down sockets to remove dirt, grease, and debris.
• Store the sockets in their original blow-molded case to protect them from damage and loss.
• Keep the case in a dry environment to prevent moisture buildup.

Corrosion Resistance:

The black oxide finish provides a layer of protection against corrosion. While durable, this finish can wear over time with heavy use. Regularly inspect sockets for any signs of rust or wear, and apply a light coat of rust-preventative oil if necessary.

5. Troubleshooting

Addressing common issues encountered during socket use.

Fastener Rounding:

• Issue: Fastener head becomes rounded, making it difficult to remove or tighten.
• Solution: Ensure the correct size socket is used. The GEARWRENCH off-corner loading design is specifically engineered to minimize this issue by applying force to the fastener flats. If rounding occurs, specialized fastener extraction tools may be required.

Socket Slippage:

• Issue: Socket slips off the fastener or impact tool.
• Solution: Verify the socket is fully seated on the fastener and securely attached to the impact tool. Check for any debris or wear that might prevent proper engagement.
