Proto J7212M Impact Socket 3/8 inch Drive 12mm 6 Point

• Proto® 6 Point Impact Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials.

• The TorquePlus™ design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners.

• The TorquePlus™ configuration employs a radius-corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage.

• The TorquePlus™ internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners.

• Socket size stamped on tool for easy identification.

• Side locking hole.

• Proto Tools have been manufactured in the USA for over 110 years, made to standards suitable for stringent aerospace requirements and heavy mining applications.
