Proto J7442 Impact Socket 1/2 in Drive 1-5/16 in 12-pt

Product Description

The PROTO J7442 is a 12-point impact socket designed for heavy-duty fastening and removal applications. Built for use with a 1/2 inch drive impact wrench or breaker bar, it accepts a 1-5/16 inch fastener and measures 2 inches in overall length. The 12-point configuration increases contact points around the fastener head, which reduces slippage during high-torque impact use. At 0.72 pounds, it is a solid, full-weight socket suited for professional use. Licensed tradespeople including HVAC technicians, plumbers, pipefitters, and electricians rely on impact sockets like this for equipment installation, flange work, and mechanical assembly where standard chrome sockets are not rated for impact use.

This socket is appropriate for use in residential, commercial, and light industrial settings wherever a 1-5/16 inch fastener is encountered. Common applications include conduit fittings, pipe flanges, equipment mounting hardware, and structural fasteners. The 1/2 inch drive size is a standard trade size compatible with a wide range of impact wrenches, torque wrenches, and extensions found in most service vans and shop setups.

Key Features

• 1/2 inch drive fits standard impact wrenches, extensions, and torque wrenches
• 1-5/16 inch socket size handles larger fasteners common in mechanical and plumbing applications
• 12-point design provides more engagement positions for faster socket placement on fasteners
• 2 inch overall length suits standard-depth fastener access without excessive extension
• Rated for impact use — unlike chrome sockets, built to absorb repeated shock loading

Compatibility

Designed as a standard 1/2 inch drive impact socket for use with 1/2 inch drive impact wrenches, ratchets, extensions, and universal joints from any manufacturer following standard drive tolerances.

Installation Notes

Impact sockets should only be used with impact-rated drive tools — do not use standard chrome hand-tool sockets in an impact wrench. Ensure the socket is fully seated on the drive anvil and the fastener before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Follow applicable torque specifications for the fastener and assembly per the equipment manufacturer or relevant code.
