Gearwrench 84311N Impact Socket 3/8 in Drive 10mm 6-point

Product Description

The GEARWRENCH 84311N is a 3/8 inch drive, 10mm hex impact socket built for professional-grade fastener work. Manufactured from chromium-molybdenum steel with a black oxide finish, this 6-point standard-length socket measures 1.102 inches overall length and weighs 0.08 pounds. The off-corner loading design transfers torque away from fastener corners, reducing rounding under high-torque impact conditions. High-visibility laser-etched size markings paired with secondary hard-stamped markings ensure fast identification in the field, even when the socket is worn or coated in grime. Licensed HVAC technicians, plumbers, electricians, and general trade professionals regularly reach for impact sockets like this one when working with impact wrenches and drivers on mechanical assemblies.

This socket is suited for metric fastener applications across a wide range of trade and industrial settings. The 10mm size is one of the most common metric fastener dimensions encountered in mechanical, HVAC equipment, and electrical panel work. The standard length profile fits flush in tight spaces where deep sockets would be obstructed. The 3/8 inch drive connects directly to 3/8 inch impact wrenches and ratchets, making it a direct drop-in for existing 3/8 inch drive tool sets. It is not insulated and is not rated non-sparking, so it is intended for standard mechanical service environments rather than live-electrical or explosive-atmosphere applications.

• Off-corner loading design protects fastener flats during impact use
• High-visibility laser-etched markings plus secondary hard-stamped size markings for fast identification
• Meets ASME B107.33M standards for impact socket performance
• Lifetime warranty from GEARWRENCH

Compatibility

Designed as an OEM-style replacement and standard-service impact socket compatible with 3/8 inch drive impact wrenches and ratchets accepting metric 10mm sockets.

Installation Notes

This socket is installed and used by trade professionals including HVAC technicians, electricians, plumbers, and general mechanics. Before servicing any equipment, de-energize electrical systems and shut off mechanical power sources per applicable codes. Confirm the socket drive size matches the impact tool anvil before use. Do not use impact sockets with standard hand-ratchet torque wrenches, as impact-rated sockets are not designed for calibrated torque applications.
