Engineered for both performance and durability, this deep socket from Proto is designed to tackle a wide range of fasteners, particularly those that are stubborn or damaged. With a 12-point configuration, it fits snugly onto fasteners, providing an effective grip without rounding off edges, which is especially beneficial for fasteners made from softer materials. The innovative TorquePlus internal design enhances ease of use, allowing for reliable engagement on the flats rather than the corners, which helps extend the life of both the socket and the fastener. Finished in a full polish chrome to resist corrosion and maintain a clean appearance, this 21 mm socket is a vital addition for any toolkit, ensuring you can confidently address a variety of mechanical challenges.

Features

• Proto 12 Point Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials.
• 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 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.
