Wera 05059500001 Slotted Power Screwdriver Bit 4 Piece

Product Description

The WERA 05059500001 is a slotted power screwdriver bit set designed for use with power tools and impact drivers equipped with a 1/4 inch hex drive. The bit features a 5/16 inch blade width and a 0.060 inch blade thickness, making it suitable for driving larger slotted fasteners in demanding trade applications. At 3.5 inches overall length, the bit provides added reach in confined or deep-set work areas. This set includes 4 pieces and is built for repeated high-torque cycling in professional environments.

This bit set is suited for electricians, HVAC technicians, plumbers, and general contractors who regularly drive slotted screws in panel work, equipment installation, or fixture assembly. The 1/4 inch hex shank is compatible with standard quick-change bit holders and power screwdrivers. The extended 3.5 inch overall length aids access in boxes, enclosures, and other recessed mounting points where shorter bits lose reach.

Installation Notes

Insert the 1/4 inch hex shank fully into the bit holder before driving to ensure secure seating. Confirm the blade width matches the fastener slot width before applying power to avoid cam-out or fastener damage. Do not use with manual-only screwdrivers not rated for power-bit inserts. Inspect bit tips for wear regularly, as a worn slotted tip increases cam-out risk on torque-sensitive connections.
