The WERA 05059604001 is a power screwdriver bit engineered for use with powered screwdriving tools in professional trade and assembly applications. The bit features a 2.5 mm hex specialty point size and a 4.00 mm body diameter, making it suited for precision fastening tasks where consistent torque delivery and bit fit are critical. With an overall length of 2 inches, it is compatible with standard power tool bit holders. Licensed tradespeople and assembly technicians working in electrical, HVAC, and mechanical installation environments commonly stock this bit for repetitive fastening work.
This bit is designed for powered screwdriving applications requiring a 2.5 mm hex specialty drive. It fits standard quarter-inch hex power tool chucks and is well suited for both residential and light commercial installation work. The 2 inch overall length provides clearance for most inline and pistol-grip power screwdrivers. Electricians, HVAC technicians, and mechanical contractors will find this bit useful wherever 2.5 mm hex fasteners appear in panel, fixture, or equipment assembly.
Designed for use in standard quarter-inch hex power screwdriver chucks and impact drivers that accept 2.5 mm hex specialty point bits.
Insert the bit fully into the tool chuck and confirm it is locked before use. Inspect the bit tip for wear before each use, as a damaged tip can strip fasteners. Use the appropriate torque setting on the power tool to avoid overdriving fasteners. Bits should be stored in a dry environment to prevent corrosion.
