Industrial 22517 Flank Socket Three Eighths Inch Drive 6 Point 17mm

The Sonic Tools 22517 Flank Socket is a 3/8-inch drive, 6-point socket sized for 17 mm fasteners, engineered to bite into the flats of hex bolts to resist cam-out and minimize rounding under torque. Crafted from chrome-vanadium steel, this flank socket belongs to Sonic’s line that features corner reliefs to engage the fastener on the flats rather than on the corners for a more secure bite. The 17 mm size in the 3/8" drive category is widely used for metric hex heads encountered in automotive and industrial repair tasks—from engine components to suspension hardware where a 17 mm socket is needed. The flank design helps maintain grip even on slightly worn fasteners, and the 3/8" drive offers a practical balance of accessibility and torque for typical workshop applications. Part number 22517; compatible with standard 3/8" drive ratchets and common extension tools, this socket is a reliable choice for technicians who want a dependable, non-slip engagement on 17 mm hex hardware.
