Proto, J5421M, Socket, 1/2 in Drive; 21 mm, 12-Point, Full Polish Chrome

Engineered for exceptional performance, this 21 mm socket from Proto features a robust 12-point design that enhances grip on fasteners, allowing for swift and efficient engagement. The innovative TorquePlus configuration shifts contact away from the edges of the fastener, thereby reducing the risk of rounding and improving durability, making it especially useful for stubborn or damaged fasteners, as well as those made from softer materials. Its full polish chrome finish not only adds to its aesthetic appeal but also ensures longevity and ease of maintenance, making this socket a reliable choice for both professional and DIY tasks.

Features

• 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.
• 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.
