WERA 9-Piece Multi-Color Stainless Steel Hex-Plus L-Key Set

1. Product Overview

The WERA 9-Piece Multi-Color Stainless Steel Hex-Plus L-Key Set is a high-quality tool collection designed for precision and durability. This set features a unique 'Take it easy' tool finder system, where each L-key is color-coded by size for quick and easy identification. The L-keys are made from stainless steel, offering superior corrosion resistance, especially when working with stainless steel fasteners.

Key features include:

• Stainless Steel Construction: Prevents extraneous rust on stainless steel screws.
• Hex-Plus Geometry: Extends the life of socket head screws by providing a larger contact surface.
• Holding Function: For sizes 3.0 and above, the long arm securely holds the screw to the tool.
• Ball Head on Long Arm: Allows for angled use, providing flexibility in tight spaces.
• Ergonomic Hose Cover: Ensures comfortable operation even in low temperatures.
• Practical Clip: Made from wear-resistant material for secure storage and transport.

2. Setup and Components

Your WERA Hex-Plus L-Key Set comes pre-assembled in its practical clip holder. No initial setup is required beyond removing the set from its packaging.

Components:

• 9 x Stainless Steel Hex-Plus L-Keys (sizes typically include 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10mm, with specific sizes indicated by color and markings).
• 1 x Wear-resistant clip holder.

The 'Take it easy' tool finder system assigns a distinct color to each L-key size, making it effortless to select the correct tool for your application. The size is also clearly marked on the L-key itself and on the holder.

3. Operating Instructions

These L-keys are designed for driving and loosening hexagonal socket screws. The Hex-Plus profile ensures a larger contact surface inside the screw head, reducing the risk of rounding out the screw and extending its lifespan.

Basic Operation:

1. Select the Correct Size: Identify the appropriate L-key size using the color-coding and size markings on the tool and holder.
2. Insert the L-Key: Insert the short arm of the L-key fully into the hexagonal socket of the screw. For screws in hard-to-reach areas, the long arm with its ball head can be used at an angle (up to 30 degrees).
3. Apply Torque: Turn the L-key clockwise to tighten or counter-clockwise to loosen the screw. Apply steady, controlled pressure.
4. Utilize Holding Function (Sizes ≥ 3.0): For L-keys sized 3.0mm and larger, the long arm features a holding function. This allows the L-key to securely grip the screw, preventing it from falling off the tool during insertion or removal, particularly useful in overhead or confined spaces.

Always ensure the L-key is fully seated in the screw head before applying significant torque to prevent damage to both the tool and the fastener.

4. Maintenance and Care

Proper maintenance will ensure the longevity and optimal performance of your WERA L-key set.

• Cleaning: After use, wipe down the L-keys with a clean, dry cloth to remove any dirt, grease, or debris. For stubborn grime, a mild cleaning solution can be used, followed by thorough drying.
• Storage: Always return the L-keys to their practical clip holder after use. This keeps them organized, prevents loss, and protects them from damage. Store the set in a dry environment to prevent any potential corrosion, although the stainless steel material offers excellent resistance.
• Inspection: Periodically inspect the L-keys for any signs of wear, bending, or damage. Discontinue use of any damaged tools to prevent injury or damage to fasteners.
• Lubrication: No lubrication is typically required for these tools.

5. Troubleshooting

Most issues with L-keys relate to improper use or tool selection.

• L-key slips in screw head: Ensure you are using the correct size L-key. The Hex-Plus profile is designed to fit snugly. If the screw head is stripped, the L-key may not be able to engage properly.
• Difficulty turning screw: Ensure the L-key is fully inserted into the screw head. If the screw is seized or overtightened, apply penetrating oil or use a longer lever arm for increased torque, if safe to do so. Do not use excessive force that could damage the tool or fastener.
• L-key bending or breaking: This indicates excessive force or using the wrong size tool. Always select the correct size and apply controlled force. WERA tools are designed for durability, but misuse can lead to damage.
• Rust on L-keys: While these are stainless steel, prolonged exposure to harsh chemicals or corrosive environments without cleaning can still cause surface discoloration. Clean immediately after exposure to such substances.
