Calculation method
Calculation method
Projection remaining after supplied stack, signed (mm)
Projection−wheel−spacer−other supplied axial stack.
Modeled threaded engagement clipped to usable nut depth (mm)
max(0,min(remaining projection,usable nut threaded depth)).
Complete engaged turns
Exact floor(engagement/pitch), using scaled decimal integers.
Fractional modeled engaged turns
Engagement/pitch; partial threads are not counted as complete turns.
Engagement minus supplied required length (mm)
Signed difference to an externally supplied engagement requirement; no requirement is inferred.

Assumptions & limits
Assumptions & limits
- An axial thread-length arithmetic model using measured usable threads. Chamfers, blind-bottoming, seat form, thread strength, torque and fastening suitability are not established; matching the supplied number is not installation approval.
