Industrial 22517 Flank Socket 3 8 Inch Drive 6 Point 17mm

Sonic 22517 is a 3/8" drive flank socket, 6-point, sized for 17 mm fasteners. Designed for mechanic work and automotive repair, its flank-drive geometry grips the flats of hex fasteners to reduce rounding under torque, making it a practical choice for stubborn or seized fasteners. The tool measures about 28 mm in overall length with a drive height around 11.5 mm and a 17 mm opening width, and it uses an internal square drive per DIN 3120 / ISO 1174 with a bullet-trap slot for secure engagement with the drive tool. Compatible with standard 3/8" drive ratchets and extensions, this socket targets metric fasteners commonly encountered in automotive service and light industrial maintenance. The part number is 22517, with a related deep variant cataloged as 2256317 in Sonic’s lineups and distributor literature.
