Hex L‑key set Top Tools 35D051, size range 1.5–10 mm, 9 pieces, ball end

Top Tools hex L-key set 35D051 contains nine L-shaped hex keys with sizes from 1.5 to 10 mm and ball ends on the long arm. The set is supplied in a compact holder that keeps tools organised and accessible. Ball-end geometry on the long arm allows engaging fasteners at an angle, while the short arm provides extra leverage for tightening or loosening. The set is intended for general assembly, maintenance and repair tasks where metric hex fasteners are used.

Advantages

The ball ends provide up to approximately 25° of entry angle for working in confined or awkward positions without removing the tool from the fastener. A compact holder keeps the nine keys arranged by size for quick selection and secure storage. The combination of short and long arms gives a balance between torque and reach useful across a range of applications. The tools are made to standard metric dimensions for compatibility with common hex fasteners.

How to use

Select the correct size key that fits the hex fastener snugly to avoid rounding. Use the short arm inserted into the fastener for higher torque applications or use the long arm for better reach. When working at an angle, engage the ball end on the long arm to access the fastener up to the allowable entry angle. Return keys to the holder after use to keep sizes organised and to protect the tips from damage.

Usage recommendations

Inspect the keys before use and avoid applying excessive force that could strip fasteners or deform the tool. For critical torque settings, use appropriate torque tools rather than relying on L-keys. Store the set in a dry place to prevent corrosion and maintain accurate fit.
