5. To calculate reaming depth, tapping depth and lag screw length, subtract 10 mm from the reading. For example:

    a. Direct reading ...............80 mm
    b. Reamer setting ..............70 mm
    c. Tapping depth (optional) .70 mm
    d. Lag screw length ...........70 mm *

* lf the Compressing Screw will be used, allow for additional compression of the fracture by selecting a lag screw 5 mm shorter (in this case, 65 mm) and inserting it an additional 5 mm.
