The SONIC 2256317 flank socket is a 3/8-inch drive, deep-well, 6-point socket sized 17 mm, designed to engage hex fasteners with a deeper reach for recessed applications. Its deep geometry allows access to fasteners located in tight spaces, while the 6-point profile provides firm contact with hex heads for turning with a standard 3/8" drive ratchet or torque tool. Identified by part number 2256317, this socket is part of Sonic’s flank socket lineup and is well-suited for automotive, machinery, and equipment maintenance tasks where 17 mm fasteners are encountered.
