A nut runner mounting structure for supporting one or more nut runner spindles includes a spindle supporting base plate, and at least one support pillar extending in parallel with the spindles and secured at its forward end to the base plate and at its rear end to a mounting structure support. Each support pillar has a tube element provided with a forward end piece and a rear end piece, and a tension bolt engaging the rear end piece and the base plate to exert an axial clamping force on the tube element. The forward end piece is formed with sharp edged teeth for penetrating into and forming matching teeth in the tube element and the base plate for locking the tube element against rotation. Clamping units are attachable to the tube elements for carrying additional equipment and connecting the structure to a mounting structure support.

A method is provided for determining the optimum control parameter values for a screw joint tightening process carried out by a power wrench which is controlled by a programmable control system utilizing the determined parameter values. The control system is provided with screw joint tightening characteristic parameter values and operation parameter values characteristic of the actually used power wrench. The tightening process is mathematically simulated by using the screw joint and power wrench characteristic parameter values as well as pre-chosen operation control parameter values. And the result of the simulated tightening process is evaluated in view of predetermined evaluation criteria, thereby determining the suitable operation control parameter values to be used during production tightening of the actual type of screw joint.
