Proto J7321MHT 1/2″ DRIVE THIN WALL DEEP IMPACT SOCKET 21 MM – 6 POINT

Proto J7321MHT Features

• 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.
• 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 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.
• 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.
• 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.
