Wera 05060149001 Square Recess Power Screwdriver Bit

Product Description

The WERA 05060149001 is a square recess power screwdriver bit designed for use with impact drivers and power screwdrivers equipped with a 1/4 inch hex drive. Built to a Number 3 specialty point size, this bit measures 2 inches in overall length and ships as a 4-piece set. The 5.50 mm body diameter provides solid engagement in the fastener recess, reducing cam-out under high-torque conditions. This bit is suited for trade professionals who need reliable, repeatable fastener drive performance on the job site or in the shop.

Square recess drive bits at the Number 3 point size are commonly used in construction, electrical rough-in, and general mechanical assembly where Robertson-head fasteners are specified. The 1/4 inch hex shank fits standard quick-change bit holders, power screwdrivers, and impact drivers across most major tool platforms. The 2-inch overall length suits most standard power tool chuck depths without adapters. Compatible screw sizes include 12, 14, and 1/4 inch fasteners as specified by the manufacturer.
