How to use

Select the hex key with the matching metric size and insert it fully into the hex socket of the fastener. Turn the key clockwise to tighten and counterclockwise to loosen, applying steady force and using the longer arm for greater leverage when needed. Keep the keys in their compact holder after use to maintain organization and protect the tool tips.

Recommendations

Use the exact matching metric size to avoid rounding fastener heads. Do not apply excessive force beyond the key's leverage; if a fastener is seized, apply penetrating lubricant or use a larger tool designed for higher torque.
