1. Torque the fastener down, then untighten the joint and retighten it. 2. Redesign of the fastening joint (for example, replace soft gaskets with a sealing compound). 3. Torque the fastener, wait briefly and then apply torque again (can be repeated in several steps). 4. Use a power assembly tool with a low RPM setting to apply the final torque.
Because of such friction changes, the use of torque auditing methods (measuring the backoff - or crack-off torque or the tightening or crack-on torque) to assess if the bolt …

Static torque is a torque that does not produce an angular acceleration. A few examples of static torque are as follows: • A person pushing a closed-door is applying a static torque because the door isn't rotating despite the force applied. • Pedalling a cycle at a constant speed is also an example of static torque as there is no ...
The use of any of the three methods for torque auditing of threads which have been bonded by adhesive does present problems. If the cured bond is broken to check the torque, the vibration resistance of the fastener …
Torque auditing prevents over- or undertorquing fasteners and detects missing fasteners. It also validates the fastening process, the torque tool, the product design and the materials used for the …
An audit that fails to provide pertinent insights into improving the fastening process is rendered ineffective. Practical experimentation may be required to achieve proper …
This process, commonly known as a "torque audit," focuses on assessing the residual torque and is often integrated into the ongoing quality control procedures. Reasons for Auditing Torque.

Dentinal crack is related not only to the design of the instrument but also to its instrument's kinematics. When rotary instruments are employed, they exert a torque force on the canal walls, potentially resulting in the formation of microcracks in the root dentin. Few studies have addressed the role of torque in dentinal crack formation.
Each of these techniques is a practical method of determining the torque remaining in the joint or the capability of the installation tool; however, the true object of tightening a fastener is to...
Torque auditing can be successful if performed on noncritical joints that feature low scatter in both friction characteristics and installation torque. On more critical joints and those with high scatter in the installation
performing a residual torque audit and analyzing the torque-angle signature. From the audit, the actual residual torque value can be found as well as the tension in the joint. The residual torque can be monitored by simple inspection of the audit plot. In order to determine the amount of clamp load in the

Under the external and cyclic loads, the fatigue crack will propagate. After some propagation of the screw, and when there is enough capacity against the fatigue load, total failure occurs. A fatigue crack can be initiated by corrosion or an impurity in the screw material, by cutting quality of threads or by an accidental load (impact).
Sometimes achieving proper torque requires practical experimentation. In order to experiment data is required. Depending on the audit strategy or information desired different techniques should be considered. Torque …
The algorithm starts measuring above torque threshold and when the angle reaches the audit angle (represented by the dash vertical line on the graph) then the audit torque is saved. The auditor will need to have a good understanding of the joint types, because the audit angle needs to be set manually. For a hard joint we would suggest a smaller ...
