A 3/4" impact socket with a 1/2" drive square. Impact sockets are made for the hammering output of an impact wrench or impact driver, where a standard hand socket can crack; the heavier wall absorbs that shock instead of passing it on to the socket walls.

• Drive size: 1/2" square
• Socket size: 3/4"
• SAE fractional size
• For use with impact wrenches and impact drivers
