Advantages

How to use

Insert the 1/4" (E 6.3) shank into a compatible bit holder, screwdriver or power driver. Select the Torx T40 bit and engage it fully into the screw head before applying torque. Use steady, controlled pressure to avoid cam-out. After use, store bits in their case or a magnetic holder to prevent damage.
