Gearwrench 84340N Impact Socket 3/8 in Drive 17mm 6-pt

Product Description

The GEARWRENCH 84340N is a 17mm, 6-point impact socket built for use with 3/8 inch drive impact wrenches and ratchets. Constructed from chromium-molybdenum steel with a black oxide finish, it is engineered to handle the high-torque demands of impact tools without cracking or deforming. The socket measures 2.48 inches overall length and weighs 0.39 pounds. High-visibility laser-etched markings provide fast size identification on the job, and secondary hard-stamped size markings back them up if the laser etching wears. Off-corner loading geometry contacts the flat faces of fasteners rather than the corners, reducing the chance of rounding. Meets ASME B107.33M standards.

This socket is suited for automotive, fleet, and general mechanical work where a metric 17mm fastener is common — wheel lug nuts, suspension components, and engine hardware frequently call for this size. It is intended for use with standard 3/8 inch drive impact tools and is appropriate for both shop and field use. The black oxide finish resists corrosion in typical shop environments. Installation is performed by licensed mechanics, automotive technicians, and trade professionals working on light-duty vehicles or mechanical assemblies requiring metric fasteners.

Key Features

• 6-point contact geometry reduces fastener rounding under impact loads
• Chromium-molybdenum steel construction rated for impact tool use
• High-visibility laser-etched size markings for fast identification
• Secondary hard-stamped markings provide a backup size reference
• Black oxide finish for corrosion resistance in shop environments
• Meets ASME B107.33M standard for impact sockets

Compatibility

Designed as a direct-fit 3/8 inch drive metric impact socket for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a 17mm socket.

Installation Notes

Always confirm the drive size of your impact tool matches the 3/8 inch drive of this socket before use. Never use impact sockets with standard hand-tool chrome sockets or adapters not rated for impact torque. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found. This socket is not insulated and is not rated for use on energized electrical components.
