The 25.4 / 4 mm hex shank ensures positive engagement with chucks and quick-change adapters, reducing slippage during torque application. At 50 mm long, it balances reach and control, allowing access to recessed fasteners while maintaining stability. The holder is compatible with standard screwdriver bits, enabling fast bit changes and broad toolset compatibility.

How to use

Insert the selected screwdriver bit into the holder until it seats firmly. Place the hex shank into the drill or driver chuck or quick-change adapter and secure according to the tool manufacturer’s instructions. Use appropriate speed and torque settings for the screw type and material. Remove and replace bits by pulling them out of the holder, using pliers if necessary for tight fittings.
