1. Product Overview

Key features include:
- SureGrip Drive Design: This innovative design grips the side of the fastener, not the corner, which significantly increases strength and helps prevent rounding of rusted or damaged fasteners.
- Durable SuperKrome Finish: The high-polish SuperKrome plating provides exceptional corrosion resistance and a long-lasting, jewelry-like finish.
- Rugged Steel Construction: Cold forged from high alloy US steel, ensuring maximum strength and longevity.

2. Setup
Setting up your SK 20mm socket is straightforward:
- Select the Correct Drive Tool: Ensure you have a 1/2 inch drive ratchet, breaker bar, or torque wrench.
- Attach the Socket: Align the square drive opening of the socket with the drive tang of your tool. Push the socket firmly onto the tool until it clicks into place, ensuring a secure connection.
- Verify Size: Confirm that the 20mm socket size matches the fastener you intend to work with.
3. Operation
Using the SK 20mm socket effectively:
- Position the Socket: Place the socket squarely over the head of the fastener (nut or bolt). Ensure it is fully seated to prevent slipping.
- Apply Force:
- For loosening: Apply steady, counter-clockwise force to the ratchet or tool handle.
- For tightening: Apply steady, clockwise force. If using a torque wrench, tighten to the specified torque value.
- Utilize SureGrip: The SureGrip design will engage the sides of the fastener, providing a strong grip and reducing the risk of rounding, especially on stubborn or slightly damaged fasteners.
- Remove the Socket: Once the task is complete, pull the socket off the fastener and then off the drive tool.
Important: Always wear appropriate safety gear, such as safety glasses, when using hand tools. Do not use damaged tools.
4. Maintenance
Proper maintenance will extend the life and preserve the finish of your SK socket:
- Cleaning: After each use, wipe the socket clean with a dry cloth to remove dirt, grease, and debris. For stubborn grime, a mild degreaser or solvent can be used, followed by a thorough drying.
- Corrosion Prevention: The SuperKrome finish provides excellent corrosion resistance. However, to maintain its integrity, avoid prolonged exposure to moisture or harsh chemicals. If stored in a humid environment, a light coat of rust-preventative oil can be applied.
- Storage: Store the socket in a dry environment, preferably in a tool chest or socket rail, to prevent loss and protect it from damage.
- Inspection: Periodically inspect the socket for any signs of wear, cracks, or damage. Discontinue use of any damaged tools to ensure safety and prevent fastener damage.
5. Troubleshooting
While SK sockets are designed for reliability, here are some common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Socket slips on fastener | Incorrect socket size; fastener head is severely rounded or stripped; socket not fully seated. | Ensure correct 20mm socket size. Fully seat the socket. If fastener is too damaged, consider a specialized extraction tool. |
| Socket stuck on drive tool | Dirt or debris in drive opening; tight fit. | Wiggle the socket while pulling. Clean the drive opening and tool tang. Apply a small amount of lubricant if necessary. |
| Socket shows signs of rust | Prolonged exposure to moisture or corrosive substances. | Clean with a rust remover (if minor). Ensure proper drying and storage in a dry environment. Apply a light rust-preventative oil. |
