Proto, J5209M-TT, Tool Tether Socket, 3/8 in Drive; 9 mm; 12 Point; Chrome Finish

The Proto Tool Tether Socket is designed with functionality and durability in mind, featuring a 3/8 inch drive and a robust 9 mm size that seamlessly adapts to various fastening needs. Its innovative TorquePlus design enhances performance by allowing quick engagement with fastener flats, significantly reducing the risk of rounding and improving the lifespan of both the fastener and tool. With an effective chrome finish applied post-hole boring, this socket offers exceptional corrosion resistance, ensuring it stands up to the demands of any workspace. Additionally, the integration of a unique Positive Control System ensures that the socket maintains secure attachment, enhancing safety and precision during use, particularly with stubborn or damaged fasteners.

Features

• Proto Tethered Tool Sockets are manufactured with four detent holes so that the pin detent will engage correctly regardless of the direction the socket is placed on the square drive
• Chrome finish is applied after the holes are bored for better corrosion resistance
• 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 internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners
• 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 Positive Control System requires a separate tool to attach or remove the socket, meaning it cannot be removed without specific intent
• Proto 12 point sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials
