Industrial 2155012 Flank Socket Deep 12mm Tool

SONIC 2155012 Flank Deep Socket is a 1/4-inch drive, six-point deep-well socket sized for 12 mm hex fasteners, designed to reach recessed fasteners in cramped spaces. This flank-style socket belongs to Sonic Equipment’s 1/4-inch drive family and mates with standard 1/4-inch drive ratchets, extensions, and adapters, providing a precise fit on metric hardware. The deep profile provides extra reach for long studs or recessed bolts, while the 12 mm opening corresponds to common metric nuts and bolts found in automotive service and industrial machinery. With its six-point geometry, it engages the flats on hex fasteners, reducing cam-out during torque application. The 2155012 variant is the 12 mm option in Sonic’s flank deep socket lineup, a focused choice for professionals needing reliable access to 12 mm fasteners in engines, gearboxes, and equipment, and is consistently described in Sonic catalog entries as a 1/4-inch drive flank deep socket for 12 mm hex fasteners.
