Gearwrench 84309N Impact Socket 3/8 in Drive 8mm 6-pt

Product Description

The GEARWRENCH 84309N is a 3/8 inch drive, 8mm, 6-point hex drive impact socket designed for use with impact wrenches and drivers in professional trade and industrial applications. Constructed from chromium-molybdenum steel with a black oxide finish, it delivers the strength and corrosion resistance required for repeated impact use. At 1.102 inches overall length, this is a standard-length socket suited for general fastener access. High-visibility laser-etched markings allow quick size identification during fast-paced work, and secondary hard-stamped size markings provide a backup reference when the primary markings wear. The off-corner loading design reduces fastener rounding, extending the life of both the socket and the fastener.

This socket is well suited for automotive, mechanical, and industrial maintenance tasks where an 8mm metric fastener must be driven under impact load. The 3/8 inch drive size makes it compatible with standard 3/8 inch impact wrenches and drivers commonly used by mechanics, HVAC technicians, and plumbers for panel removal, equipment mounting, and equipment servicing. The standard length profile works in a wide range of accessible fastener locations. It is sold as a single unit and is appropriate for both shop and field use.

Compatibility

Designed as an OEM-style replacement or addition for use with 3/8 inch drive impact wrenches and drivers requiring standard-length 8mm metric sockets.

Installation Notes

Install and remove this socket with the impact tool powered down and the fastener area clear of rotating equipment before engagement. Ensure the socket is fully seated on the drive anvil before applying impact force to prevent drive damage or socket ejection. This socket is intended for impact use only and should not be substituted for hand-drive sockets in torque-sensitive applications without appropriate tooling.
