Error classification of self-tapping screw fastenings in automated assembly

open access: yes, 2002
Torque signature signals during the insertion of self-tapping screws insertions can be used to monitor the process. Although it has been shown that artificial neural networks provide an effective means of monitoring screw fastenings, the research to date

Biomechanical evaluation of peak reverse torque (PRT) in a dynamic compression plate-screw construct used in a goat tibia segmental defect model

open access: yesBMC Veterinary Research, 2019
Background Peak reverse torque (PRT) is a valid method to evaluate implants’ secondary stability in the healing bone. The secondary stability is achieved by the implant over time and it has been positively correlated with the implants’ osseointegration ...

Danger of self-drilling self-tapping screws [PDF]

open access: yesThe Egyptian Orthopaedic Journal, 2018
Some locking plate systems make use of self-drilling and self-tapping screws. Theoretically, this technology facilitates insertion and decreases operative time. This case illustrates one possible danger of broken screws in these systems. They may carry a
