Wera 05059478001 Slotted Power Screwdriver Bit 4 Piece

Product Description

The WERA 05059478001 is a slotted power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. Built for repetitive fastening tasks, this bit features a 5/32 inch blade width and a 0.030 inch blade thickness, giving it a precise fit in slotted screw heads sized 3F-4R. The 2-3/4 inch overall length provides clearance in tight or recessed work areas. This set includes 4 pieces, making it practical for job sites where bits see regular wear. Licensed electricians, HVAC technicians, and general trade professionals who use 1/4 inch hex drive power tools will find this a direct-fit consumable for their existing bit holders.

This bit is suited for light commercial and residential trade applications where slotted fasteners are encountered, including panel work, equipment enclosures, and general mechanical assembly. The 1/4 inch hex shank is compatible with standard quick-change bit holders and power screwdrivers. The 4.00 mm body diameter keeps the bit profile compact for work in confined spaces. Trades that regularly service slotted hardware will benefit from having multiples on hand given the consumable nature of screwdriver bits in power tool use.

Installation Notes

Install into a 1/4 inch hex quick-change bit holder before use. Confirm the bit seats fully and the holder locking mechanism is engaged before applying torque. Inspect bits regularly for tip wear, as a worn slotted bit tip can cam out and damage fastener heads. Replace bits showing deformation at the blade tip to maintain fastener integrity.
