Dual Action Drive

Dual Action Drive (DAD) is a low profile bit system for fasteners you cannot reach with a socket. Each RPT bit has a 7/16 in or 17 mm hex body, so it drives from a combination wrench, the DAD ratchet or a square drive adapter. That gets a hex or star bit under a manifold, behind a bracket or inside a frame rail where a socket and ratchet have no room to swing. Metric and SAE hex, and star from T10 to T60, individually or in sets.
