Wera 05057646001 Hex Screwdriver Insert Bit 1/4 in Drive

Product Description

The WERA 05057646001 is a hex screwdriver insert bit designed for use with 1/4 inch drive power tools, impact drivers, and bit holders. Machined from stainless steel, this insert bit measures 2 inches in overall length with a maximum body diameter of 1/4 inch. The stainless steel construction provides corrosion resistance and durability across a wide range of fastening applications. This bit is a standard straight-style hex bit with no ball end, delivering solid, direct engagement with hex socket fasteners. It is suited for electricians, HVAC technicians, plumbers, and general tradespeople who require reliable bit performance in both hand-drive and power-drive setups.

This insert bit is appropriate for light commercial and residential trade applications where hex fasteners are standard. It fits any 1/4 inch drive quick-change bit holder or compatible power tool chuck. The compact 2 inch overall length keeps the tool profile low in confined spaces while still providing adequate reach for most standard fastening tasks.

Installation Notes

Insert bits should be seated fully and securely in the bit holder before use to prevent cam-out or bit ejection under load. Confirm the drive tool is set to the appropriate torque setting for the fastener being driven. Inspect the bit for wear or deformation before each use, as a worn hex profile increases the risk of fastener damage.
