  • Product typeSockets
  • Converts 3/4" drive tools to 1/2" sockets
  • Impact-rated construction withstands high-torque applications
  • 2 1/4" overall length keeps socket profile compact
  • Square-drive geometry ensures secure engagement

Drive Conversion

The Westward 21WL75 adapter connects a 3/4 inch female drive to a 1/2 inch male drive. It allows technicians to use smaller sockets with larger impact wrenches or breaker bars. The tool is built for impact applications and measures 2 1/4 inches in overall length. It suits automotive and heavy equipment maintenance where drive sizes differ.

Replacing Mismatched Sets

This adapter replaces the need to purchase duplicate socket sets in every drive size. It bridges the gap when a job requires a 1/2 inch socket but only a 3/4 inch drive tool is available. The jump is worth it when the cost of a full 3/4 inch socket set outweighs the occasional need for larger drive leverage. It eliminates the downtime of sourcing the exact matching drive tool.

Build Integration

The adapter fits directly between the drive anvil and the socket, requiring no additional hardware. Its compact length preserves access in tight engine bays or machinery frames. It frees up budget and storage space by reducing the number of dedicated drive tools a shop must stock. The non-insulated, non-sparking steel construction suits standard industrial environments.
