Proto J7222H Impact Socket 3/8 in Drive 11/16 in 6-pt

Product Description

The PROTO J7222H is a 6-point hex impact socket designed for use with 3/8 inch drive impact wrenches and rattle guns. It accepts an 11/16 inch fastener and measures 1-3/32 inches overall length, making it a compact option for close-clearance work. Built for impact service, it is rated for the high-torque, high-vibration demands that standard chrome sockets are not suited to handle. Mechanics, pipefitters, HVAC technicians, and general maintenance trades rely on this size for common fastener applications across equipment panels, flanges, and mechanical assemblies.

This socket fits standard 3/8 inch drive impact tools and is sized for 11/16 inch hex fasteners encountered in residential and light commercial mechanical work. Its 6-point design concentrates drive force on the flats of a fastener rather than the corners, reducing the risk of rounding under high torque. The compact 1-3/32 inch overall length suits confined spaces where longer sockets cannot engage properly.

Key Features

• 3/8 inch drive fits standard impact wrenches and rattle guns
• 11/16 inch socket size for common hex fasteners
• 6-point contact geometry reduces fastener rounding under impact torque
• 1-3/32 inch overall length suits tight clearance installations
• Designed for impact service, not standard hand-drive use

Compatibility

Designed as an OEM-style impact socket for use with 3/8 inch drive impact wrenches across residential and light commercial mechanical service applications.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench or breaker bar only — do not use with standard chrome ratchets not rated for impact service. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage. Inspect the socket for cracks or deformation before each use, and remove from service if damage is found.
