Gearwrench 84341N Impact Socket 3/8 in Drive 18mm

Product Description

The GEARWRENCH 84341N is a 6-point hex drive impact socket designed for demanding fastener work in automotive, industrial, and mechanical service applications. Built from chromium-molybdenum steel with a black oxide finish, this socket is engineered to withstand the high-torque output of pneumatic and electric impact drivers. The 3/8 inch drive accepts standard 3/8 inch impact wrenches and ratchets. At 2.48 inches overall length, it fits in tight access points where longer sockets would bind. High-visibility laser-etched markings and secondary hard-stamped size markings make size identification fast in any lighting condition. Meets ASME B107.33M standards.

This socket is used in professional shop environments and field service settings where 18mm hex fasteners appear on engines, chassis components, suspension systems, and heavy equipment. It suits licensed mechanics, fleet technicians, and industrial maintenance professionals working with metric fasteners. The 6-point contact geometry reduces the risk of fastener rounding under load by engaging flats rather than corners, a key advantage when breaking loose seized or corroded fasteners.

Key Features

• Chromium-molybdenum steel construction rated for impact tool use
• Black oxide finish for corrosion resistance and glare reduction
• 6-point hex drive off-corner loading design reduces fastener rounding
• High-visibility laser-etched markings for quick size identification in the field
• Secondary hard-stamped size markings as a backup reference
• Meets ASME B107.33M standards for impact socket performance
• Covered by a limited lifetime warranty

Compatibility

Designed for use with standard 3/8 inch drive impact wrenches, air ratchets, and hand ratchets. Fits any 3/8 inch square drive tool and is sized for 18mm metric hex fasteners.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench or ratchet. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage. Inspect the socket for cracks or deformation before each use, and do not use hand-socket-rated tools in place of impact-rated equivalents. This socket is not insulated and is not rated for electrical work near energized components.
