Press-fit-bolts are designed primarily for the connection of flange couplings and patented as early as 1986. After clamping, these sit free of backlash in the holes. Just a few press-fit-bolts offer fast and simple assembly compared with relatively many screws for connecting flanges. Their simple handling also makes press-fit-bolts ideal for other applications requiring face to face joins. 

For exact dimensioning and the suitable choices, we need a diagram of the application and details on the maximum generated torque, bending moment, and (possibly) axial force.
