## Long description

The Wera 840/4 IMP DC Hex-Plus DIY screwdriver bit is a premium replacement bit designed for hexagonal socket screws. It features a 5 mm Hex-Plus tip, a 50 mm working length and a 1/4" hexagonal shank compatible with holders to DIN ISO 1173-F 6.3. Manufactured in the Czech Republic, the bit uses Impaktor technology and a rough diamond-particle coating on the tip to increase service life and reduce slippage under high torque.
Advantages
Impaktor technology provides increased durability under impact and high-load conditions. The diamond-particle coating on the tip raises friction resistance to minimize cam-out. Hex-Plus geometry increases contact surface in the screw head, reducing notch effect and greatly lowering the risk of screw damage. The 1/4" hex shank ensures compatibility with standard bit holders.
Suitable for
 DIY assembly and repair work
 High-torque fastening with impact drivers
 Applications requiring reduced screw head wear
 Use with 1/4" bit holders meeting DIN ISO 1173-F 6.3

How to use
Insert the 1/4" hex shank into a compatible bit holder or impact driver. Engage the 5 mm Hex-Plus tip with the hexagonal screw head, apply steady axial pressure and operate the driver at an appropriate torque or impact setting. For optimal engagement, ensure the bit tip fully seats in the screw recess before applying torque. After use, store the bit in a suitable holder to protect the coated tip.
Usage recommendations
Use this bit for tasks that require higher resistance to cam-out and impact loads. Avoid using a damaged or excessively worn tip; replace the bit when wear impairs secure engagement. Match torque and impact settings of power tools to the screw and material to prevent over-stressing the fastener.
