The highest tightening torque is achieved after approx. 3 to 5 seconds impacting/tightening action. The torque build-up depends on the following of factors: • The hardness of the material in the bolts/nuts. • The type of washer (disk washer, spring washer, seal). The hardness of the material (s) to be joined by the fastener. The lubricants (if any) at the surface of the junction. Examples: The maximum torque is reached after a relatively short impacting/tightening interval when joining metal to metal with a disk washer. A moderate interval of impacting/tightening action is required when joining metal to metal where a spring-ring washer, disk-spring washer, stud bolt, or bolt/nut with conical seats are used. A longer interval of impacting/tightening action is necessary to arrive at the maximum tightening torque when joining metal to wood or insulation material.
