Industrial 2256318 Flank Socket 3/8 Deep 6-Point 18mm

Sonic 2256318 Flank Socket, 3/8" drive, deep, 6‑point, 18 mm, is a precision hand tool designed for metric hex fasteners in automotive and industrial work. This 18 mm flank socket fits hex heads and is compatible with standard 3/8" drive ratchets and extensions, with its deeper profile providing access to fasteners located in recessed or tight spaces. The 6-point interior offers secure engagement with hex fasteners across six contact points, promoting stable torque transfer and reducing cam-out in compatible setups. Part of Sonic Tools' flank socket lineup, this size sits alongside 16 mm and other metric options (for example 2256316, 2256318) in the same family, enabling builders to assemble complete 3/8" drives kits. The 3/8" drive size balances turning power with accessibility for mid-range torque tasks, making it a practical choice for maintenance, automotive service, and equipment repair where metric fasteners are used. For best results, pair with a compatible ratchet and keep tools clean and free of damage to maintain precise hex engagement.
