Proto J7446H Impact Socket 1/2 in Drive 1-7/16 in 6-point

Product Description

The PROTO J7446H is a 6-point impact socket designed for heavy-duty fastening applications in professional trades. Built from alloy steel, it accepts a 1/2 inch square drive and fits 1-7/16 inch hex fasteners. The overall length is 2-15/64 inches, keeping the profile compact for work in tighter spaces. The 6-point contact geometry distributes torque evenly across fastener flats, reducing rounding under high-impact loads. This socket is manufactured to ANSI B107.2 standards and carries a lifetime warranty. It is suited for use with pneumatic, electric, and cordless impact wrenches in mechanical, HVAC, plumbing, and industrial service environments.

This socket is a standard choice for technicians working on equipment assemblies, pipe flanges, heavy mechanical connections, and structural fasteners that require 1-7/16 inch hex drive access. The 1/2 inch drive size is the most common impact platform in trade service kits, making this socket a direct fit for a wide range of impact wrenches already in the field. Residential and commercial service technicians, pipefitters, and millwrights will find it useful across a broad range of equipment service tasks.

Installation Notes

Install and remove using a 1/2 inch drive impact wrench or ratchet only — do not use hand-socket extensions with impact drivers. Inspect the socket for cracks or deformation before each use and retire any damaged socket immediately. Always ensure the fastener is fully seated in the socket before applying torque to prevent slippage. Follow applicable torque specifications from the equipment manufacturer for the fastener being driven.
