Proto J7338H Impact Socket 1/2 in Drive 1-3/16 in 6-point

Product Description

The PROTO J7338H is a 6-point impact socket designed for heavy-duty fastening and removal applications. Built for use with 1/2 inch drive impact wrenches and rattle guns, it accepts a 1-3/16 inch hex fastener and measures 3.5 inches in overall length. The 6-point contact geometry concentrates torque on the flats of the fastener rather than the corners, reducing the risk of rounding under high-impact loads. Installed by mechanics, millwrights, plumbers, and HVAC technicians, this socket handles the high-cycle, high-torque demands common in trade and industrial service work.

This socket is suited for residential and commercial service applications where a 1/2 inch drive impact tool is the standard choice. Typical use cases include tightening or removing large hex-head bolts and nuts on equipment, flanges, structural connections, and mechanical assemblies. The 3.5-inch overall length provides enough reach for recessed fasteners without excessive flex or socket wobble during impact use.

Key Features

• 1/2 inch drive fits standard impact wrenches and torque wrenches
• 1-3/16 inch socket size for large hex fasteners
• 6-point design reduces fastener rounding under impact torque
• 3.5-inch overall length for moderate-depth reach
• Impact-rated construction intended for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style replacement and general-use impact socket compatible with standard 1/2 inch drive impact wrenches, torque wrenches, and ratchets across residential and commercial trade applications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or tradesperson familiar with impact tooling. Ensure the socket is fully seated on the drive anvil and fastener before applying impact force. Do not use impact sockets with hand-ratchet-only tools not rated for impact loads. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
