Wera 05059795001 PH3 Phillips Power Screwdriver Bit 1/4 in Hex

Product Description

The WERA 05059795001 is a PH3 Phillips power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. With an overall length of 3.5 inches, this bit reaches fasteners in recessed or hard-to-access locations. The PH3 point size fits large-head Phillips screws common in heavy framing, structural assembly, and industrial fastening applications. Licensed electricians, HVAC technicians, and general contractors use this bit in cordless and corded screwdriving applications where a secure, positive fit to the fastener head is required to prevent cam-out and reduce operator fatigue.

This bit is suited for trade professionals who regularly drive large Phillips fasteners in residential and light commercial construction, equipment assembly, and panel installation. The 3.5 inch length provides added reach compared to standard-length bits, making it practical for work inside enclosures, junction boxes, and equipment panels. The 1/4 inch hex shank is the industry-standard drive size compatible with the vast majority of power screwdrivers, impact drivers, and bit holders used in the trades.

Installation Notes

Insert the 1/4 inch hex shank fully into the bit holder or chuck before operating the tool. Ensure the PH3 point is fully seated in the fastener head before applying torque to minimize cam-out and bit wear. Power screwdriver bits should be inspected regularly for tip wear and replaced when the point shows visible rounding or deformation.
