2. To screw–fasten the measuring body use eight DIN EN ISO 4762
hexagon–socket screws, property class 10.9 (measuring range
10 kNVm: 12.9), of the appropriate length (depending on the connection
geometry, see Table 4.1).
We recommend, particularly for 50 N⋅m, 100 N⋅m and 200 N⋅m situations,
fillister-head screws DIN EN ISO 4762 or similar, blackened,
smooth-headed, permitted size and shape variance in accordance with
DIN ISO 4759, Part 1, product class A.
WARNING
The screw heads (Z), see Fig. 4.1, must not fit tight to the adapter flange.
With alternating load: Use a screw locking device (e.g. LOCTITE no. 242)
to glue the screws into the counter thread in order to prevent slackening
and loss of pre–tensioning.
3. Before finally tightening the screws, turn the torque flange on the centering
until all screw heads are located more or less centrally in the clearance
bores on the connection element. The screw heads may in no case be in
contact with the sides of the adapter-flange clearance-bores.
4. Fasten all screws with the specified fastening torque (Table 4.1).
5. For further installation of the shaft run, there are eight threaded bores on
the adapter flange. Also use screws of property class 10.9 (or 12.9) and
fasten with the fastening torque specified in Table 4.1.
