Wera 05057671001 Square Recess Bit No. 2 1/4 in Hex 4 Pc

Product Description

The WERA 05057671001 is a power screwdriver bit set designed for square recess (Robertson) fasteners. The set includes 4 bits, each sized at No. 2 point with a 1/4 inch hex shank for compatibility with standard power tool chucks and bit holders. Each bit measures 2 inches in overall length, making it suitable for general-purpose fastening tasks in tight and open spaces alike. This bit is used by electricians, HVAC technicians, plumbers, and general contractors who regularly drive square recess screws in panels, equipment enclosures, and structural assemblies.

Square recess bits are a staple on residential and light commercial job sites where Robertson-head screws are standard. This 4-piece set provides redundancy for high-volume fastening work or impact driver use where bit wear is accelerated. The 1/4 inch hex drive fits the overwhelming majority of cordless drills, impact drivers, and screw guns used in the trades. The 2-inch bit length clears most standard driver chucks without sacrificing control in confined spaces.

• 2 inches overall length for general-purpose fastening reach

Installation Notes

Insert the 1/4 inch hex shank fully into the bit holder or chuck before driving to prevent slipping or cam-out. When using with an impact driver, ensure the bit is rated for impact use and inspect for wear after high-cycle applications. Replace bits showing signs of rounding at the tip to avoid fastener head damage.
