1/2 in Drive Impact Socket Deep Socket, black oxide, Steel, 21 mm

Specifically designed for light clearance applications
Reduced wall thickness helps improve access to fasteners in restricted areas
All Impact sockets feature one through hole and a groove to accept a retaining ring and pin to secure the socket to the power tool anvil

Additional Features:

• Chamfered service ends for quick and positive fastener engagement
• Proto® 6 Point Impact Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials
• The TorquePlusTM design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners
• The TorquePlusTM 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 TorquePlusTM internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners
• Thin wall sockets are lightweight
• Designed to fit into smaller spaces
• Thinner walls help improve productivity by making it easier to gain access to fasteners in confined spaces
• Extra deep length helps improve access in confined areas
• Often used in application where fasteners are close together, such as tire service
