Gearwrench 81200D 3/8 in Drive Socket Extension Set 4pc

Product Description

The GEARWRENCH 81200D is a four-piece 3/8 inch drive socket extension set designed for professional technicians who need reach and flexibility in tight or deep fastener applications. The set includes four extensions in 1.5, 3, 6, and 12 inch lengths, covering the most common reach requirements in HVAC service, plumbing rough-in, electrical panel work, and general mechanical repair. All four pieces are chrome-finished steel, meeting ASME standards for dimensional accuracy and strength. This set suits any trade professional who regularly works with 3/8 inch drive ratchets and sockets.

This extension set is suited for residential and light commercial service work where a single set covers the range from shallow fastener access to deep-well reach. The four lengths allow technicians to swap quickly between close-clearance and extended-reach situations without changing drive sizes. Typical applications include equipment panel removal, motor mounting hardware, and bracket fasteners in confined spaces.

Key Features

• Four-piece set covers 1.5, 3, 6, and 12 inch extension lengths in a single package
• Chrome finish provides corrosion resistance for tool storage and field use
• Steel construction meets ASME standards for dimensional accuracy
• 3/8 inch drive compatibility works with standard ratchets, breaker bars, and torque wrenches
• Non-locking design allows fast socket swaps without a release mechanism

Compatibility

Designed for use with any standard 3/8 inch drive ratchets, torque wrenches, and sockets conforming to ASME drive tool specifications.

Installation Notes

Extensions should be inspected for cracks or deformation before each use and removed from service if damaged. When using extensions with a torque wrench, be aware that longer extensions can introduce flex and affect applied torque accuracy. Store extensions separately from impact tools, as this set is not rated for impact driver use unless otherwise specified by the manufacturer.
