Wera 05056535001 Phillips Insert Bit 4 Point 1/4 in

Product Description

The WERA 05056535001 is a Phillips screwdriver insert bit designed for use with 1/4 inch hex drive tools. Built to a No. 4 point size and measuring 1-1/4 inches in overall length, this bit handles larger fasteners found in heavy-duty assembly and service work. The ductile and tough construction resists cam-out and tip deformation under high-torque conditions, extending service life compared to standard chrome steel bits. It seats into any 1/4 inch hex bit holder, impact driver, or screwdriver handle with a quick-change chuck, making it a direct grab-and-go replacement on the job.

This insert bit is suited for electrical, HVAC, plumbing, and general mechanical trades where No. 4 Phillips fasteners appear in panel assemblies, equipment enclosures, and mechanical connections. The compact 1-1/4 inch length is optimized for bit holders and right-angle adapters in tight quarters. Trades using power screwdrivers, impact drivers, or manual bit handles will find this bit compatible with standard 1/4 inch hex tooling across most major tool brands.

Key Features

• No. 4 Phillips point size for large-head fasteners common in equipment and panel work
• 1/4 inch hex drive fits standard bit holders, quick-change chucks, and impact drivers
• 1-1/4 inch OAL suits bit-holder extensions and compact right-angle adapters
• Ductile and tough material construction reduces tip wear and cam-out under load

Compatibility

Designed as a standard 1/4 inch hex shank insert bit compatible with any 1/4 inch hex bit holder, screwdriver handle, or impact driver accepting insert-style bits.

Installation Notes

Insert the bit fully into the 1/4 inch hex holder or chuck before applying torque. Confirm the point size matches the fastener recess before driving - using an undersized or oversized point causes cam-out and fastener damage. For power tool use, set torque clutch to the appropriate fastener specification. Inspect the tip for deformation regularly and replace when the point shows visible wear.
