Proto J7438H Impact Socket 1/2 in Drive 1-3/16 in 6-point

Product Description

The PROTO J7438H is a 6-point impact socket designed for heavy-duty fastener work in trade and industrial applications. Built for use with a 1/2 inch drive impact wrench or breaker bar, it accepts a 1-3/16 inch hex fastener and delivers the torque transfer and wall thickness needed for impact-rated use. The overall length is 2 inches, keeping it compact for tight-clearance work. Licensed mechanics, HVAC technicians, plumbers, and electricians reach for impact-rated sockets when standard chrome sockets would crack or slip under high torque. This socket is designed to absorb the hammering action of pneumatic and electric impact tools without fracturing.

The J7438H is suited for residential and commercial service work where 1-3/16 inch fasteners appear on equipment mounts, pipe flanges, structural hardware, or mechanical assemblies. Its 6-point geometry reduces the chance of rounding a fastener compared to 12-point designs, making it a reliable choice when working with worn or corroded hardware. Compact at 2 inches overall length, it fits into recessed fastener locations that longer sockets cannot reach.

Key Features

• 1/2 inch drive size compatible with standard impact wrenches and breaker bars
• 1-3/16 inch socket size for precise fastener engagement
• 6-point hex geometry reduces fastener rounding under high torque
• 2 inch overall length suits tight-clearance and recessed installations
• Impact-rated construction absorbs hammering action from pneumatic and electric tools

Compatibility

Designed as an OEM-style replacement or direct-use impact socket for any 1/2 inch drive impact wrench, breaker bar, or ratchet requiring a 1-3/16 inch 6-point hex socket.

Installation Notes

This socket is installed and removed by trade professionals including mechanics, HVAC technicians, plumbers, and electricians. Always confirm the drive tool is de-energized or disconnected from the air supply before changing sockets. Use only impact-rated sockets with impact wrenches — do not substitute standard chrome hand-tool sockets. Inspect the socket for cracks or deformation before each use and replace if damage is found.
