Wera 05057672001 Square Recess Power Bit No3 1/4in Hex 4pc

Product Description

The WERA 05057672001 is a Square Recess power screwdriver bit set designed for use with power tools and impact drivers equipped with a 1/4 inch hex shank. Each bit measures 2 inches in overall length and is sized for Number 3 square recess fasteners, making it a practical choice for high-torque driving applications. The set includes 4 pieces, providing redundancy on jobs where bit wear is a factor. Licensed tradespeople working in electrical, HVAC, and general construction will find this bit size common in panel boxes, equipment enclosures, and structural fastening tasks.

Square Recess Number 3 bits are frequently used in residential and light commercial construction and service work where Robertson-head fasteners appear in electrical enclosures, junction boxes, and prefabricated assemblies. The 1/4 inch hex drive fits standard quick-change chuck systems found on cordless drills, impact drivers, and dedicated power screwdrivers. At 2 inches in length, these bits offer a compact profile suitable for most standard-depth driving scenarios without excessive flex.

Installation Notes

Install bits into the tool chuck with the power source off or the tool locked. Confirm the bit is fully seated in the quick-change chuck before driving. Match the Number 3 square recess bit to the correct fastener head size to avoid cam-out and fastener damage. Inspect bits for wear or deformation before each use and replace damaged bits promptly.
