Design offices and maintenance departments must regularly define tightening torque values for their assemblies taking into account the surface condition of the screws/nuts used.
The materials used and their surface condition (rust, lubrication, class...) have an impact on the bolted assemblies' efficiency. The tightening torque values must therefore be calculated or adapted according to the characteristics of the bolted assemblies.
