Wera 05073391001 L-Shaped Hex Key Set

The Wera 05073391001 is a 9-piece metric L-shaped hex key set manufactured in the Czech Republic. Keys feature the Hex-Plus profile for increased contact area inside the screw head, reducing notching and lowering the risk of damaging the screw recess. A ball end on the long arm allows insertion at an angle for working in confined or awkward positions. The keys are chrome-plated for corrosion resistance and come in a wear-resistant clip fastener that holds the tools securely and permits simple removal.

Advantages

Hex-Plus profile increases contact surface to minimize rounding of hex socket screws. Ball-end on the long arm enables angled entry and use in difficult installation situations. Chrome plating provides corrosion protection, and laser-engraved size markings are wear-resistant for quick tool identification. The durable clip fastener keeps all nine L-keys organized and easy to transport.

Suitable for

• Assembly and maintenance of machinery and equipment

How to use

Select the hex key that matches the screw size and insert the short or long arm into the screw recess as required. For standard straight access use the short arm for greater torque; for angled or hard-to-reach screws use the long arm with the ball-end to allow insertion at an angle. Apply steady torque and avoid excessive force to prevent damage to the screw or tool.

Recommendations

Store the L-keys in the supplied clip fastener to keep sizes organized. Clean and dry keys after use and inspect the hex ends regularly; replace keys that show significant wear to avoid damaging screw heads.
