The Hikoki 751971 is a universal adapter designed to expand the versatility of your power tools by converting a 1/4" hexagonal shank into a 1/4" square drive. This allows you to use standard socket attachments with tools that typically feature hexagonal chucks, such as cordless drills or screwdrivers. Measuring 65 mm in length, the adapter features a built-in fixing ball that ensures a secure connection, preventing the socket from slipping during use. It is a practical addition for anyone needing to switch quickly between driving screws and tightening bolts without changing their primary tool.
