## Long description

Wera 840/4 IMP DC SB SiS 6 mm is a hex screwdriver bit manufactured from alloy tool steel with a diamond-coated tip. Designed for use with impact-compatible drivers, the bit provides a secure fit in hex socket screws and is intended for professional workshop, assembly, and maintenance tasks. The diamond coating increases friction at the contact surface, helping to reduce cam-out and extending operational life under frequent use.
Advantages
The diamond-coated tip offers enhanced slip resistance compared with uncoated bits, improving torque transfer and reducing rounding of screw heads. Manufactured from hardened alloy tool steel, the bit delivers high wear resistance and consistent shape retention. The 6 mm hex profile ensures compatibility with a wide range of fasteners, and the design is optimized for use in impact drivers to withstand shock loads.
Suitable for
 Driving and removing 6 mm hex socket screws
 Use with impact-compatible drivers and impact screwdrivers
 Workshop assembly and mechanical maintenance
 Professional trades where repeated fastening is required
Key specifications
 Tip shape: 6 mm hex (HEX)
 Material: alloy tool steel (hardened)
 Tip coating: diamond-coated surface for improved grip
 Compatibility: designed for impact-capable drivers
 Intended use: fastening hex socket screws
How to use
Insert the 6 mm hex bit into the chuck or bit holder of an impact-capable driver until it seats securely. Ensure the driver is set to the appropriate torque or impact setting for the task and the screw material. Align the bit with the hex socket screw and apply steady pressure while operating the driver. Periodically inspect the bit tip for wear and replace it when the diamond coating or hex profile shows significant rounding or chipping to maintain performance and avoid damage to screw heads.
Usage recommendations
Use the bit with compatible impact drivers and avoid excessive side loading. Store in a dry, clean environment to preserve the diamond coating and prevent corrosion. For best results, match torque settings to screw size and material and replace the bit when wear affects fit or engagement.
