The NEIKO 30249A Impact Socket Adapter Set is a practical add-on for any garage or tool bag when your impact driver, wrench, or ratchet doesn’t match the socket you want to use. Designed for square-drive conversion, it lets you size up or down across common SAE drive sizes so you can keep working without hunting for a different tool.

Built from heavy-duty drop-forged, heat-treated chrome vanadium steel and finished with a black phosphate coating, these adapters are made to hold up to repeated use. Each piece features a spring-loaded ball detent to help keep sockets locked in place, plus through-holes that allow the use of locking pins for added security when needed.

What’s included: 2 reducers (3/8″ female to 1/4″ male; 1/2″ female to 3/8″ male) and 3 adapters (1/4″ female to 3/8″ male; 3/8″ female to 1/2″ male; 1/2″ female to 3/4″ male).

  • 5-piece impact-grade adapter/reducer set for converting square drive sizes up or down (SAE)
  • Drop-forged, heat-treated chrome vanadium steel construction for strength and durability
  • Black phosphate coating for a tough, long-lasting finish
  • Spring-loaded ball detent helps keep sockets securely attached
  • Through-holes allow use of locking pins for added stability during demanding jobs
