Siemens SIMOTICS L-1FN3 User Manual

Thread depth and screw-in depths in the primary section
The following drawing schematically illustrates the minimum permissible and maximum screw-
in depth of the 󹪝xing screws in the screwed-in state. For selecting the screw length, a good
range is thus made available to the machine manufacturer.
The selection of the length of the mounting screws while taking all of the design tolerances
into consideration is the responsibility of the machine manufacturer.
The machine manufacturer must ensure that the minimum screw-in depth is reached and the
maximum screw-in depth is not exceeded.

Minimum permissible screw-in depth
The minimum permissible screw-in depths for the most commonly used materials for a
machine bed are listed below. For di󹪜erent materials, you must determine the screw-in depth
according to VDI Directive 2230.
