Gearwrench 84406 3/8 in Drive Impact Socket Extension 3 in

Product Description

The GEARWRENCH 84406 is a 3/8 inch drive impact socket extension designed for use with impact wrenches and ratchets in professional trade and mechanical service applications. With an overall length of 3 inches, this extension adds reach between the drive tool and socket without sacrificing torque transfer. The black finish provides corrosion resistance in shop environments. Weighing 0.086 pounds, it is a compact, lightweight addition to a mechanic's or technician's drive tool set. It meets ASME standards for dimensional accuracy and performance. Licensed mechanics, HVAC technicians, and plumbers routinely use 3/8 inch drive extensions for fastener access in confined spaces.

This extension is suited for residential and commercial service work where a 3/8 inch drive is the appropriate torque range. Common applications include HVAC equipment service, plumbing fixture installation, appliance repair, and general mechanical work. The 3 inch overall length provides moderate reach for accessing recessed fasteners in equipment panels, junction boxes, and mechanical assemblies. It is compatible with standard 3/8 inch drive impact sockets and impact-rated ratchets.

Installation Notes

Do not use non-impact-rated extensions with impact wrenches.
