How to use

Select the hex key that fits the fastener snugly to avoid rounding. Insert the short or long arm into the fastener depending on required torque and reach: use the long arm for greater reach and the short arm for higher torque. Turn steadily and avoid excessive force that could damage the fastener head. After use, place the keys back into the holder to maintain organization and to protect the tips from wear.

Usage recommendations

For best results, match the exact metric size to the fastener, keep keys clean and free of debris, and store the set in a dry place to minimize corrosion. Use a properly fitting key and controlled force when working with delicate components to prevent damage.
