Proto J7312 Impact Socket 1/2 in Drive 3/8 in 12-point

Product Description

The PROTO J7312 is a 12-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. It accepts a 3/8 inch fastener and measures 3.25 inches overall length, giving technicians the reach needed for recessed fasteners without sacrificing control. Built for the torque demands of pneumatic and electric impact tools, this socket is suited for automotive, industrial, and heavy equipment applications where standard chrome sockets would crack or shatter under impact loading. At 0.43 pounds, it is a compact, single-piece tool intended for professional use.

This socket fits into service workflows where a 1/2 inch drive impact tool is already in use and a 3/8 inch fastener needs to be driven or removed. Common scenarios include suspension work, drivetrain service, equipment assembly lines, and utility maintenance. The 12-point configuration allows engagement at more clock positions than a 6-point socket, which can be useful in tight quarters where full rotation of the tool is not possible. It is sold individually and ships as a single unit.

Key Features

• 1/2 inch drive fits standard impact wrenches and torque multipliers
• 3/8 inch socket size for common fastener applications
• 12-point geometry allows engagement at multiple clock positions

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive impact wrenches in automotive, industrial, and mechanical service applications.

Installation Notes

Install and remove only with 1/2 inch drive impact tools or torque wrenches rated for impact use. Do not use impact sockets with standard chrome ratchets or breaker bars not rated for impact service. Ensure the socket is fully seated on the drive anvil and the fastener before applying torque. Inspect the socket for cracks or wear before each use and replace if deformation is visible.
