Proto J7446M Impact Socket 1/2 in Drive 46mm 6-point

Product Description

The PROTO J7446M is a 6-point impact socket designed for heavy-duty fastener removal and installation in professional trade and industrial settings. Built from alloy steel, it accepts a 1/2 inch drive and fits 46mm hex fasteners. The 6-point contact geometry reduces the risk of rounding fastener heads under high-torque impact loads. At 2-7/16 inches overall length, it offers a compact profile suited for tight-access work. This socket meets ASME B107.33M standards and carries a limited lifetime warranty, making it a dependable choice for mechanics, millwrights, heavy equipment techs, and industrial maintenance crews.

The J7446M is used wherever 46mm hex fasteners appear in heavy equipment, truck drivetrain work, agricultural machinery, and industrial machinery maintenance. Its 1/2 inch drive sizing fits the impact wrenches and ratchets most commonly found on commercial service trucks and in shop environments. The alloy steel construction handles the repeated stress cycles generated by pneumatic and electric impact drivers without cracking or deforming under normal service conditions.

Key Features

• 6-point drive profile reduces fastener rounding under impact torque
• Alloy steel construction rated for impact tool use
• 1/2 inch square drive fits standard impact wrenches and ratchets
• 46mm socket size for large hex fasteners common in heavy equipment and drivetrain applications

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive impact wrenches, ratchets, and torque wrenches requiring a 46mm 6-point hex socket.

Installation Notes

Install the socket fully onto the drive anvil before applying torque to prevent slippage or ejection under load. Always use impact-rated sockets with impact tools — do not substitute standard chrome hand-tool sockets in pneumatic or electric impact applications. Inspect the socket for cracks, chips, or wear before each use and remove from service if damage is found.
