3. Key Features

• SuperKrome Finish: High polish plating provides long-lasting durability and maximum corrosion resistance.
• SureGrip Drive Design: Drives the side of the fastener, not the corner, to increase torque and prevent rounding of rusted or damaged fasteners.

• 15-Degree Offset Head: Both box and open ends feature a 15-degree offset for improved clearance and access to fasteners in tight areas.

• Rugged Steel Construction: Cold-forged with high carbon alloy steel for maximum strength and durability.

4. Setup and Storage

Your wrench set comes with a lockable wrench rack designed for convenient and secure storage. Proper storage helps protect the tools from damage and keeps them organized.

4.1 Initial Setup

1. Remove the wrenches from their packaging.
2. Place each wrench securely into its designated slot in the included wrench rack. The rack uses a friction-fit design to hold the wrenches in place.

4.2 Storage Recommendations

• Always store the wrenches in the provided rack when not in use.
• Store the rack in a clean, dry environment to prevent moisture accumulation and potential corrosion, despite the SuperKrome finish.
• Avoid storing in areas with extreme temperatures or high humidity.

5. Operating Instructions

Combination wrenches are versatile tools used for tightening or loosening nuts and bolts. Follow these instructions for safe and effective operation:

5.1 Selecting the Correct Wrench Size

• Always select the wrench that precisely matches the size of the fastener (nut or bolt head). Using an incorrect size can damage both the fastener and the wrench, and may lead to injury.
• This set includes metric sizes: 25mm, 26mm, 27mm, 29mm, 30mm, and 32mm.

5.2 Proper Engagement

• Open End: Position the open end fully onto the fastener, ensuring it seats completely around the flats.
• Box End (12-Point): Slide the box end over the fastener. The 12-point design allows for easier engagement from multiple angles. The SureGrip design will engage the sides of the fastener, reducing the risk of rounding.

5.3 Applying Force

• Always pull on the wrench handle rather than pushing, to prevent injury if the wrench slips.
• Apply steady, even pressure. Avoid sudden jerking motions.
• For stubborn fasteners, apply penetrating oil and allow it to work before attempting to loosen.
• Never use a pipe or other extension on the wrench handle to increase leverage, as this can overstress and damage the wrench or fastener.

5.4 Using the 15-Degree Offset

• The 15-degree offset on both ends provides useful clearance. When working in tight spaces, flip the wrench over to gain a different angle of approach if the handle interferes with obstructions.

6. Maintenance and Care

Proper maintenance will extend the life of your SK Tools wrenches and ensure they remain in excellent working condition.

• Cleaning: After each use, wipe down the wrenches with a clean, dry cloth to remove dirt, grease, and debris. For stubborn grime, a mild degreaser can be used, followed by a thorough drying.
• Corrosion Protection: While the SuperKrome finish offers excellent corrosion resistance, storing the tools in a dry environment is crucial. If exposed to moisture or harsh chemicals, clean and dry them immediately.
• Inspection: Periodically inspect your wrenches for any signs of damage, such as cracks, bends, or excessive wear on the jaws. Do not use damaged tools.
• Lubrication: No lubrication is required for these wrenches.

7. Troubleshooting

Most issues with wrenches stem from improper use. Here are common scenarios and solutions:

7.1 Wrench Slipping or Rounding Fastener

• Cause: Incorrect wrench size, worn wrench, or improper engagement.
• Solution: Ensure the wrench size precisely matches the fastener. Make sure the wrench is fully seated on the fastener. The SureGrip design minimizes rounding, but proper fit is still essential. Replace any worn wrenches.

7.2 Difficulty Loosening Stubborn Fasteners

• Cause: Rusted or overtightened fastener.
• Solution: Apply a penetrating oil to the fastener and allow it to soak for several minutes. Use steady, increasing pressure. Avoid excessive force that could damage the wrench or fastener.
