Proto, J5321M, Deep Socket, 1/2 in Drive, 21 mm, 12-Point, Metal, Full Polish Chrome

The Proto 21 mm deep socket is engineered for both performance and longevity, making it an essential tool for tackling stubborn or damaged fasteners. With a unique TorquePlus internal design, this socket not only minimizes the risk of rounding off fasteners but also extends their lifespan by allowing for easier handling of worn or rusted components. Its 12-point configuration enhances socket engagement by focusing on the fastener flats rather than the corners, effectively distributing stress and reducing slippage, which is particularly beneficial when working with soft materials. Crafted from high-quality metal and finished in full polish chrome, this socket combines durability with a refined look, making it a reliable choice for any mechanic or DIY enthusiast.

Features

• 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.
• Proto 12 Point 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.
