Tightening torques

Details on precise tightening torque value:
Applies to screws, bolts and nuts, in so far as they are able to be accessed with a torque wrench and be thus tightened. Tightening torques in this category are displayed as follows: Example: 4 Nm
Details on approximate tightening torque value:

Applies to screws, bolts and nuts, in so far as they are unable to be accessed with a torque wrench and be tightened with one. Tightening torques in this category are displayed as follows:

Example: Nm ≈ 4

Tolerance details in basic data

For system engineering reasons tolerance details within the basic "tightening torque" and "test and adjustment values" data cannot be displayed conform to standards. Therefore, the tolerance details have been defined as follows:

Examples:

35 (±5) at ≈ ° details 35° (±5')

Defined base value with equal plus and minus tolerance.

35 (-5/+10) at ≈° details 35° (-5'/+10')

Defined base value with unequal plus and minus tolerance.

35...40

Without any defined base value, within meaning of from/up to.
