Hex L‑key set Unior U607853 — L‑type Allen keys 1.5–10 mm with ball end, 9 pieces

Unior U607853 is a 9-piece L-type hex key set that covers metric sizes from 1.5 mm to 10 mm. Each key is formed in an L-shape to provide leverage for tightening and loosening hex fasteners, while the long arm features a ball end that enables angled engagement for access in confined or awkward positions. The set is supplied in a compact holder that keeps tools organized and allows quick selection of the required size for assembly, maintenance and repair tasks.

Advantages

The L-type design offers a balance of reach and torque: the short arm provides strong leverage for high-torque turning and the long arm with ball end permits insertion at angles up to approximately 25–30° for faster engagement in hard-to-reach locations. The set spans commonly used metric sizes, reducing the need for multiple individual keys. The compact holder simplifies storage and transport and aids rapid size identification during work.

Suitable for

• Bicycle assembly, adjustment and repair
• Machinery and equipment maintenance
• Furniture assembly and general workshop tasks
• Service and field repairs where compact tool sets are required

How to use

Select the hex key that matches the hex socket size of the fastener. For higher torque operations, insert the short arm into the fastener and use the long arm as a lever. For access at an angle or in tight spaces, use the ball end on the long arm to engage the fastener at an offset angle. Apply steady pressure and avoid excessive force if the key does not seat fully to prevent rounding the fastener head. After use, return keys to the holder to maintain organization and protect the tips.

Usage recommendations

Use appropriate personal protection when performing maintenance tasks. Keep keys clean and free of corrosion; store in the supplied holder to prevent loss and protect tip geometry. For high-torque fasteners, consider using the short arm for leverage and avoid levering with extensions that may overload the key.
