Specialized screw joint analysis (hourly rate)
The screw joint analysis identifies a suitable screwdriving procedure and determines the optimal shut-off torque for the screwdriving tool. Parts for assembly are positioned in an almost identical replication of the assembly conditions. Under further investigation the screw joint is subjected to a higher torque and assembled further with a corresponding angle. Additional studies and services relating to the customer-specific application are conducted.
The specialized screw joint analysis includes:
  • Examination of SEVERAL screwdriving applications and/or
    INDIVIDUAL screwdriving applications with more than
    10 screw locations for VARIOUS specific screws on the
    customer’s component.
  • Screw assembly until destruction, each graphically recorded.
  • Identification of the optimal processing parameters, such as
    screwdriving time, speed, torque, or angle as control or
    monitoring variables.
  • Recommendation for selection of drive type (electronic,
    electric, pneumatic) based on your specific processing
    requirements (torque accuracy, documentation requirements,
  • Recommendation for determining tightening strategy (torque
    assembly, friction dependent assembly, DEPRAG Clamp Force
    Control, etc.)
  • Creation of an application-specific screwdriving program
  • Identification of seating conditions: By continuing to tighten
    a joint which has already been assembled to target torque, the
    true assembly result can be assessed to optimize the
    screwdriving process.
  • Creation of a report as a PDF document in German (as standard)
    or English (please specific when ordering).
Please note that the components provided will be destroyed or damaged during the screw joint analysis and then returned to you.
Time frame:
Analysis will be conducted approx. 3 weeks after receipt of clear technical order and receipt of customer parts. Please consult with our service team to arrange a binding date for completion.
