How to use

Select the correct hex bit for the fastener and insert it into the screwdriver’s hollow shaft until the lockable thread engages.

To change bits, unlock the thread, remove the bit and replace it with the required size.

Recommendations

Use the set for tasks that require access to recessed or hard-to-reach hex fasteners. Apply moderate torque appropriate to the fastener size to avoid rounding the hex tip. Store bits dry and clean to prevent corrosion and ensure long service life.
