Apex QR-308 Socket Adapter 3/8 Drive to 1/4 Hex Bit

Product Description

The APEX QR-308 is a square-drive to hex bit socket adapter designed for use with 3/8 inch square-drive ratchets and tools that accept a 1/4 inch hex bit shank. The adapter measures 1-3/4 inches overall length with a 3/4 inch body diameter and is constructed from steel for durability under repeated torque loads. It converts a standard 3/8 inch female square drive into a 1/4 inch hex bit receiver, allowing technicians to use hex bit accessories with existing 3/8 inch drive tool sets. This adapter is a practical add-on for HVAC, plumbing, electrical, and general mechanical service work where switching between drive types is required.

This adapter is suited for residential and light commercial service environments where a technician needs to run hex bit drivers from a 3/8 inch drive ratchet, impact tool, or extension. Common applications include accessing fasteners in tight equipment compartments, panel work, and equipment assembly where hex bit sockets are preferred but only 3/8 inch drive tools are on hand. The compact overall length keeps reach manageable in confined spaces.
