Gearwrench 84331N Impact Socket 3/8 in Drive 8mm 6-pt

Product Description

The GEARWRENCH 84331N is a 6-point, 8mm hex impact socket designed for use with 3/8 inch drive impact wrenches and rattle guns. Built from chromium-molybdenum steel with a black oxide finish, this socket is engineered to handle the high-torque demands of impact tools without cracking or deforming. The overall length measures 2.441 inches. High-visibility laser-etched size markings and secondary hard-stamped markings make quick identification straightforward in the field. This socket meets ASME B107.33M standards, making it appropriate for professional trade use in HVAC, plumbing, electrical, and general mechanical applications.

The 84331N is suited for residential and commercial service work wherever an 8mm metric fastener is encountered. It is commonly used by HVAC technicians, plumbers, and electricians installing equipment, panels, and mechanical assemblies that use metric hardware. The off-corner loading design reduces the risk of rounding fastener heads, which is especially important when working with frequently cycled or corrosion-prone fasteners in mechanical rooms, rooftop units, and utility spaces. Packaged as a single socket, it fits into existing 3/8 inch drive impact sets or can be purchased as a standalone replacement.

Key Features

• Chromium-molybdenum steel construction handles high-torque impact tool loads
• 6-point hex drive geometry minimizes fastener rounding under load
• Off-corner loading design reduces contact stress on fastener flats
• High-visibility laser-etched markings for fast size identification
• Secondary hard-stamped size markings provide a permanent backup identification
• Black oxide finish for corrosion resistance in field conditions
• Meets ASME B107.33M standards for impact socket performance

Compatibility

Designed as an OEM-style metric impact socket compatible with standard 3/8 inch square drive impact wrenches and hand ratchets requiring an 8mm hex socket.

Installation Notes

Install and remove with a 3/8 inch drive impact wrench or hand ratchet. Before use on live electrical equipment or energized systems, ensure power is fully disconnected per applicable NEC or local code requirements. Note that this socket is not rated as insulated and is not non-sparking — do not use in environments where insulated or non-sparking tools are required. Inspect the socket for cracks or wear before each use, as impact tool cycling can accelerate fatigue in damaged tooling.
