Industrial 22520 Flank Socket 3/8 6-Point 20mm

Sonic 22520 Flank Socket is a 3/8-inch drive, 6-point socket sized for 20 mm fasteners, designed with a flank traction profile that grips the fastener on its flats to reduce rounding when high torque is needed. Manufactured from Chrome‑Vanadium steel and intended for hand use, this flank socket delivers precise engagement on 20 mm bolts with true 6-point contact and is compatible with standard 3/8-inch drive ratchets and extensions. The 20 mm size identifies the fastener range it fits, making it a focused tool for maintenance and assembly tasks where 3/8-inch drive access is preferred and a compact profile is important in tight spaces. This 20 mm variant sits within Sonic’s 225xx flank-socket lineup, offering technicians a size-specific option that sits between the 19 mm and 21 mm models for precise fastener selection and efficient service in automotive and general mechanical work.
