Apex UG-EX-370-4 Hex Driver Bit Adapter Square to Hex

Product Description

The APEX UG-EX-370-4 is a hex driver bit adapter that converts a 1/4 inch hex drive to a 3/8 inch square drive connection. Built for use with power tools and impact drivers, this adapter extends tooling flexibility by allowing square drive sockets and accessories to be used with hex shank tool systems. At 4 inches overall length (OAL), it provides added reach in tight or recessed fastening applications. Electricians, plumbers, HVAC technicians, and general tradespeople keep adapters like this in their kit for multi-drive tool setups. Weighing 0.2 pounds, it is compact and easy to carry in a tool pouch or bag.

This adapter is suited for residential and commercial service work where a technician needs to swap between hex and square drive accessories without changing tool heads. Typical install scenarios include equipment panel fastening, conduit work, pipe fitting, and general mechanical assembly where a 1/4 inch hex shank tool must accept 3/8 inch square drive bits or sockets. It is compatible with standard hex shank power drivers, drills, and impact drivers that accept 1/4 inch hex accessories.

Installation Notes

Insert the 1/4 inch hex shank end into the tool driver chuck and seat it fully before use. Ensure the tool is powered off and the chuck is released before inserting or removing the adapter. Verify the square drive end is fully engaged with the socket or accessory before applying torque. Inspect the adapter for wear or damage before each use and replace if deformation or play is observed.
