The DIABLO DSA0250B is a square-to-hex impact socket adapter designed to convert a square-drive socket to a 1/4 inch hex shank for use with impact drivers and drills. This adapter allows tradespeople to run standard square-drive sockets directly from a hex-shank power tool, eliminating the need for a separate impact wrench when working on light-to-medium fastening tasks. Weighing 0.033 pounds, the DSA0250B is compact and lightweight, making it easy to carry in a tool pouch or parts bag on the job.
The DSA0250B is suited for use in residential and light commercial applications where an impact driver is the primary tool on hand. Electricians, plumbers, HVAC technicians, and general contractors use adapters of this type when installing equipment panels, junction boxes, or mechanical components that require socket-drive fastening. It is sold individually and is well-suited for technicians who already carry a 1/4 inch hex impact driver and want to expand its capability to socket work.
Designed as an OEM-style accessory for use with 1/4 inch hex shank impact drivers and drills accepting standard hex-shank tooling.
Installation requires no special tools - insert the hex shank end into the tool chuck and seat the square-drive socket onto the adapter before use. Ensure the tool is powered off and the trigger is not engaged when attaching or removing the adapter. Use only with impact-rated sockets; standard chrome sockets are not rated for impact driver use and may fracture under load.
