Proto J7422M Impact Socket 1/2 in Drive 22mm 6-point

Product Description

The PROTO J7422M is a 6-point impact socket designed for heavy-duty fastener removal and installation with a 1/2 inch square drive. Built for use with air-powered and electric impact wrenches, it accepts a 22mm hex fastener and measures 1-39/64 inches overall length. The 6-point geometry concentrates drive force on the flats of the fastener rather than the corners, reducing fastener rounding under high-torque impact loads. Mechanics, millwrights, pipefitters, and other trade professionals rely on impact-rated sockets like this for production and service work where speed and durability are both required. The socket weighs 0.36 pounds and is sized for typical automotive, heavy equipment, and industrial fastener applications.

This socket is suited for use in automotive repair, fleet maintenance, industrial assembly, and mechanical service environments where a 22mm fastener is common. The 1/2 inch drive size is a standard trade drive class, compatible with the broad range of 1/2 inch impact wrenches and extensions in a typical tool inventory. It is appropriate for both shop and field use wherever controlled impact torque is applied to 22mm hex fasteners.

Key Features

• 6-point socket design reduces rounding on fastener flats under impact torque
• 1/2 inch square drive fits standard impact wrenches, extensions, and adaptors
• 22mm socket size for metric hex fasteners
• Compact 1-39/64 inch overall length suits tight-access fastener locations
• Impact-rated construction for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style replacement and standard service socket for use with 1/2 inch drive impact wrenches and hand ratchets requiring a 22mm 6-point metric socket.

Installation Notes

Impact sockets are installed and removed by mechanics and trade professionals using pneumatic or electric impact drivers rated for 1/2 inch drive. Always confirm the socket is fully seated on both the drive tool and the fastener before applying torque. Do not use impact sockets on hand-torque instruments without a rated adaptor, and do not substitute hand-socket chrome tools in impact applications. Inspect the socket for cracks or deformation before each use.
