The Proto 3/8in Drive, 21mm Metric Socket is designed for demanding applications, featuring a 12-point design for use on stubborn or damaged fasteners, and a TorquePlus drive configuration for quick and easy socket engagement. The socket's radius-corner design minimizes slippage and fastener rounding, making it ideal for working with soft materials or worn, rounded, or rusted fasteners. Its positive control system ensures secure attachment to the drive, preventing accidental removal. Suitable for use in a variety of industries, including manufacturing, construction, and maintenance, this socket offers reliable performance and durability in a compact package.
