Gearwrench 84408 Impact Socket Adapter 1/2 to 3/8 Drive

Product Description

The GEARWRENCH 84408 is an impact-rated socket adapter designed to convert a 1/2 inch square male drive to a 3/8 inch square female drive. At 1.5 inches overall length, it gives technicians and tradespeople a compact, reliable way to use 3/8 inch drive sockets with 1/2 inch impact tools. Built to ASME B107.1 standards, this adapter is suited for high-torque applications where a standard non-impact adapter would fail. It is a single-piece, solid-drive adapter — no moving parts, no locking ring — making it straightforward to use in the field or shop.

This adapter is used wherever a drive size mismatch exists between an impact wrench and the socket set on hand. Common applications include automotive service, HVAC equipment installation, plumbing rough-in, and electrical panel work where fastener access requires switching between drive sizes mid-task. It is appropriate for both shop bench work and in-field service calls. The compact overall length keeps it practical in tight fastener locations.

Installation Notes

Install and remove this adapter by hand — no tools required. Always power down or disconnect the impact wrench before attaching or removing the adapter. Inspect the adapter for cracks or deformation before each use, and do not use a damaged adapter under impact load. This adapter is intended for impact use only and should not be substituted with standard chrome-finish adapters in high-torque applications.
