Proto J61502 Hex to Square Adapter Screwdriver Bit

Product Description

The PROTO J61502 is a hex to square adapter power screwdriver bit designed for use with power drivers and impact tools that accept a 1/4 inch hex shank. The bit converts a 1/4 inch hex drive input to a 3/8 inch square drive output, allowing technicians to run standard square drive sockets using a power screwdriver or drill. Overall length is 2 inches. This adapter is a practical addition to the tool kit of HVAC techs, electricians, plumbers, and other trade professionals who need to switch between drive formats without changing tools.

This adapter bit is suited for light-to-medium fastening tasks on service calls where both a power driver and socket-drive fasteners are encountered. It fits any tool accepting a standard 1/4 inch hex shank, including cordless drills, impact drivers, and power screwdrivers commonly used in residential and commercial trade work. Sold individually, it is a compact, single-piece solution for expanding the capability of an existing 1/4 inch hex power driver.
