Gearwrench 84176 Impact Socket Adapter 3/8 to 1/4 Drive

Product Description

The GEARWRENCH 84176 is a square drive impact socket adapter designed to convert a 3/8 inch male square drive to a 1/4 inch female square drive. It is built for impact use, making it suitable for pneumatic and electric impact wrenches in professional shop and field applications. The adapter measures 1 inch in overall length and meets ASME B107.1 standards. It is a compact, single-piece tool that lets technicians run 1/4 inch drive sockets on a 3/8 inch drive impact tool without switching drives. Automotive technicians, mechanics, and general trade professionals are the primary users.

This adapter is appropriate for automotive repair shops, fleet maintenance operations, and field service work where technicians need to quickly switch between drive sizes on an impact tool. It supports applications where 1/4 inch drive sockets are needed but only a 3/8 inch impact drive is available. The compact 1 inch overall length keeps the tool profile low, useful in tight engine bays and restricted access areas.

Installation Notes

Installation requires no tools — the adapter seats directly onto the 3/8 inch drive anvil of an impact tool. Ensure the impact tool is fully depressurized or powered off before attaching or removing drive accessories. Inspect the adapter for wear or cracking before each use; do not continue using a damaged adapter under impact loads. Follow applicable shop safety practices when operating impact tools.
