Excerpt from a 3 page undated brochure from The Triangle Corporation. The first click style Craftsman torque wrenches were "produced" by Torque Controls, Inc. But also sold under the Utica name, and even under the Torque Control's name.
The handle picture I took years ago of the Craftsman and Utica branded torque wrenches. The 2 middle Craftsman ones are stamped TC, and one would say is for Torque Controls. The 2 outside ones are Utica branded. Same torque wrenches except for the ratcheting head. Torque Controls/Utica used a round head. The Craftsman branded version used a Craftsman-style ratchet head.
