Expand the utility of your existing hex bit tools with the STEELMAN 108SD14K-1 1/4-Inch Hex Bit to 1/4-Inch Square Drive Expansion Adapter. This handy accessory allows any hand driven or electrically powered screwdriver or hex bit driver to use any 1/4-inch drive socket. Made from durable tool steel for reliability, this adapter features an indented hex shaft for easy use with most corded and cordless screwdrivers fitted with quick-release chucks. The 1/4-inch square drive end of the adapter features a spring-loaded detent ball that helps secure attached sockets in place so they don't fall off during regular use but are still easily removable when you need to change sizes.
