Wera 05066410001 Square Recess Bit No. 2 1/4 in Hex Drive

Product Description

The WERA 05066410001 is a power screwdriver bit designed for square recess (Robertson) fasteners at a No. 2 point size. It features a 1/4 inch hex shank for direct insertion into power screwdriver chucks, impact drivers, and bit holders that accept the standard 1/4 inch hex drive. The overall length is 1 inch, making it a compact bit suited for tight-clearance applications. The 6 mm body diameter provides solid engagement with the fastener head, reducing cam-out during high-torque driving operations. This bit is used by electricians, HVAC technicians, plumbers, and general trade professionals who regularly drive square recess fasteners on the job.

This bit is appropriate for production and service work where square recess fasteners are common, including electrical panel assembly, HVAC equipment installation, and general mechanical assembly. The 1/4 inch hex drive is compatible with standard quick-change chuck systems found on most cordless drills and impact drivers used in the trades. Its compact 1 inch length suits confined spaces where longer bits would interfere with surrounding components. Sold as a single bit per package.
