A ball end allows operation at angles up to 25° for improved accessibility. Keys are held in a simple, clearly visible holder that enables rapid selection and secure stopping for L-keys, supporting quick and reliable operation.

How to use

Select the appropriate hex key from the holder and insert the short or long arm into the screw head as required. For straight access use the long arm; for increased torque use the short arm. The ball end permits engagement at angles up to 25°, which is useful when straight alignment is not possible. After use return the key to the designated slot in the holder for organized storage.

Recommendations

Use the correct metric key size to avoid rounding screw heads. Apply steady torque and avoid excessive force beyond the fastener rating. Keep the holder and keys clean and dry to prevent corrosion and ensure the bronzed finish performs as intended.
