Load cells are to be clamped in tightly at the mounting bores - like a
cantilever beam. Later, the load will be introduced at the other end. The
following table contains all recommended bolts and torques:

* Standard value for the property class stated. For bolt design, please note
the relevant information provided by bolt manufacturers.
NOTE
Missing washers and a base plate strength which is too low, cause most
faults that occur during load cell use. In particular, this applies to the
strength of the base plate which has a direct influence on the
"Hysteresis error" stated in the Specifications.
