Selecting the right option

Choose by square size, holder size and torque. A square drive tool has no ratchet action, so the wrench turns the socket directly. For a ratchet action see the Stahlwille 725QR 1/2" Drive QuickRelease Ratchet Insert Tools or the Stahlwille 735 1/2" Drive Fine-Tooth Reversible Ratchet Insert Tools. The 734/20 can be used with the Stahlwille 502 1/2 Connecting Square as Stahlwille lists it.
