Directions for use

Use the long arm to access deep areas and the short arm when you need greater leverage. To preserve the tool and the fixings, it is advisable to avoid impacts, unsuitable extensions and excessive force.

For a longer service life, store the key in a dry place after use and clean it if it has been in contact with dust, grease or metal particles. In a professional or regular setting, it is useful to pair it with other hex key sizes in order to cover the most frequent maintenance needs.
