All Utica screwdrivers feature aluminum housings to reduce weight and maximize durability. Utica torque screwdrivers feature a unique roller bearing cam, which produces smooth, accurate and consistent performance when tightening fasteners. When the maximum torque setting is achieved, the cam mechanism automatically slips to prevent over-tightening. Electronics assembly and other light screw assembly applications demand precision that can only be accomplished with the use of precision tools. All Utica torque screwdrivers are made of top grade materials machined to exacting tolerances. - Working parts are heat treated for added strength and durability. Then, each tool is carefully assembled by our experienced technicians. Each Utica screwdriver is calibrated according to ASME B107.14M before leaving the plant, using test equipment traceable to NIST. Utica's manufacturing processes are ISO 9001 certified, which means that Utica products are manufactured to the highest standards. Quality materials, precision machining and assembly is what makes Utica torque screwdrivers the tool of choice.
