Operating Instructions
Eklind hex keys are specifically designed for driving internal hexagon socket fasteners. Follow these guidelines for effective and safe operation:
- Select the Correct Size: Always choose the hex key that precisely fits the fastener's socket. Using an incorrect size can strip the fastener or damage the tool.
- Insert Fully: Ensure the hex key is fully inserted into the fastener's socket to maximize contact and prevent slippage.
- Utilize Ball-Hex Feature: For fasteners in hard-to-reach locations, the ball-hex end allows you to engage the fastener at an angle of up to 30 degrees. This flexibility is particularly useful in confined spaces. Apply torque carefully when using the ball end, as it is primarily for starting or removing fasteners, not for final tightening where maximum torque is required.
- Access Tight Spaces: The stubby short arm design of these keys is ideal for applications where clearance is limited. Use the short arm for maximum leverage in tight spots.
- Apply Torque: Turn the hex key clockwise to tighten and counter-clockwise to loosen fasteners. Apply steady, controlled pressure.

Maintenance and Care
To ensure the longevity and performance of your Eklind hex keys, follow these maintenance guidelines:
- Cleaning: After each use, wipe the hex keys clean with a dry cloth to remove any dirt, grease, or debris.
- Rust Prevention: The tools are coated with a rust-resistant finish. To maintain this protection, avoid prolonged exposure to moisture or corrosive substances. If necessary, a light coat of tool oil can be applied for added protection.
- Storage: Always store the hex keys in their provided plastic holder. This keeps them organized, prevents loss, and protects them from damage. Store in a dry environment.
- Inspection: Periodically inspect the tools for any signs of wear, bending, or damage. Do not use damaged tools, as this can lead to injury or further damage to fasteners.
Troubleshooting
Eklind hex keys are simple, robust tools. Most issues arise from improper usage rather than tool malfunction.
- Fastener Stripping: If a fastener head is stripping, ensure you are using the correct size hex key and that it is fully seated in the socket. Avoid excessive force, especially when using the ball end.
- Tool Bending/Breaking: This typically occurs due to applying excessive torque beyond the tool's design limits or using the tool as a pry bar. Always use the tool for its intended purpose.
- Difficulty Loosening a Fastener: For stubborn fasteners, ensure the correct size is used. Applying penetrating oil and allowing it to soak may help. Avoid sudden jerking motions.
