Gearwrench 84386N Impact Socket 3/8 in Drive 7/8 in 6-pt

Product Description

The GEARWRENCH 84386N is a 6-point impact socket designed for high-torque fastening applications in automotive, mechanical, and industrial service work. Built from chromium-molybdenum steel with a black oxide finish, this socket is rated for use with 3/8 inch drive impact wrenches and fits 7/8 inch hex fasteners. The standard-length profile measures 1.181 inches overall and provides solid access in typical underhood and chassis applications. High-visibility laser-etched size markings allow fast identification during busy work sessions, while secondary hard-stamped markings serve as a permanent backup. The off-corner loading geometry is engineered to reduce rounding on worn or marginal fasteners. Meets ASME B107.2 standards and carries a lifetime warranty.

This socket is suited for professional mechanics, fleet technicians, and trade contractors working on SAE-standard fasteners. The 3/8 inch drive size makes it practical for mid-torque impact work where a larger 1/2 inch drive setup would be overkill. Standard length is appropriate for most exposed fastener applications without the clearance limitations of a deep socket. Typical uses include suspension components, brackets, and general mechanical assembly where 7/8 inch SAE fasteners are common.

Key Features

• Chromium-molybdenum steel construction rated for impact tool use
• 6-point drive geometry for maximum contact on hex fasteners
• Off-corner loading design reduces rounding on worn fasteners
• High-visibility laser-etched size markings for quick identification
• Secondary hard-stamped size markings as a permanent backup
• Black oxide finish for corrosion resistance in shop environments
• Meets ASME B107.2 standard with lifetime warranty coverage

Compatibility

Designed for use with 3/8 inch drive impact wrenches and ratchets on 7/8 inch SAE hex fasteners. Compatible with standard 3/8 inch drive tool systems.

Installation Notes

Install and remove with a 3/8 inch drive impact wrench or ratchet — do not use with hand-turn adapters under sustained high-torque impact loads beyond tool rating. Verify fastener size before application to avoid socket or fastener damage. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. This socket is not insulated and is not rated for live electrical work.
