Caution!
If the screw thread greased, tightening torques are therefore to
minimize, since due immediately higher clamping forces are achieved
by lower coefficients of friction at the same torque. The manufacturer
shall in this case, no statement and makes no values available on the
actually occurring forces and surface pressures at the base plates.
Please ensure in their own interest to comply with the conditions for
fitting the screw head and thread not greased, counterbore in the base
plate of grease!
