Sonic 2256312 Flank Deep Socket 6 Point 12mm Tool

SONIC 2256312 is a 3/8-inch drive flank deep socket, 6-point (six‑point) for 12 mm hex fasteners. Constructed from chrome vanadium steel, it delivers durability for automotive and mechanical maintenance. The internal opening is 12 mm, designed to grip hex bolts and nuts without rounding, while the socket depth is 49.9 mm and it weighs 62 g, offering reach into recessed fasteners with a balanced, manageable mass. The 3/8-inch drive mates with standard ratchets and extensions, making it compatible with a wide range of tool sets. The flank-drive geometry engages the fastener on its flats to reduce cam-out and wear during turning, which is especially helpful in tight spaces common to automotive work. This model is typically used for 12 mm hex fasteners in automotive repairs and other mechanical applications where access depth is limited and a longer socket is advantageous.
