The Article represents theoretical and empirical methods of estimating the characteristics of impact wrenches when torquing specific threaded connections and in fixed anvil mode. They allow addressing the following issues: indirect determination of single impact energy in production conditions based on the proposed technique of estimating specific characteristics of stiffness and impact threshold of the wrenches, which are used to obtain base of the initial design values of the mathematical model. These methods and the techniques developed based on them allow for determination of single impact energy both in laboratory and production environment, which is important at the stage of tool creation as well as during its operation in order to reasonably develop the size range of impact wrenches, carry out strength analysis of their striking mechanisms and choose a proper tool for a specific range of threaded connections. The correct choice of the tool can make installation procedure much more efficient due to the reduced time for assembly and ability to control torquing tightness of threaded connections. In hydrotechnical construction a significant amount of work falls on assembling threaded connections in the use of metal structures, products, and in used construction equipment.
