Using this hex driver is easy. First, use the color - coded tool finder to quickly pick the right one for the job. Hold the ergonomic handle firmly and insert the tip into the screw. For tight or awkward spaces, swivel the tool axis as needed. When using it, avoid applying too much force suddenly to prevent damage to the tool or the screw. After use, clean the tool with a dry cloth to keep it in good condition. Store it in a dry place to prevent corrosion, especially because of the great corrosion - protection feature of the Wera Black Point tip. With proper care, this hex driver will serve you well for all your bike maintenance tasks.
