Wera 05056420001 PH1 Phillips Power Screwdriver Bit

Product Description

The WERA 05056420001 is a PH1 Phillips power screwdriver bit designed for use with 1/4 inch hex drive power tools and electric screwdrivers. It features a Bi-Torsion construction, which adds a torsion zone to the shank that absorbs torque peaks and reduces bit breakage during high-speed fastening. The overall length is 1 inch, making it suited for compact power screwdriver chucks and quick-change holders. This bit is built for trade professionals who drive Phillips fasteners repeatedly under production or service conditions and need a bit that holds up to power tool stress.

This bit is appropriate for residential and light commercial applications where PH1 Phillips fasteners are common, including electrical panel work, fixture mounting, and general mechanical assembly. It fits any standard 1/4 inch hex quick-change chuck, including those found on cordless drills, impact-rated screwdrivers, and dedicated screwguns. The single-piece packaging makes it easy to stock individually or as part of a job-site bit kit.

Installation Notes

Insert the bit fully into a 1/4 inch hex quick-change chuck before operating the tool. Confirm the fastener recess is clean and matches PH1 size to avoid cam-out and bit wear. Always disconnect or power down the tool before changing bits. This bit is intended for power tool use and is not rated for manual-only torque applications where longer bit lengths are typically required.
