There are a great number of torque wrench systems available on the market where the wrench grip can be replaced with other types. These wench grips are suitable for torque tightening screwed joints in poorly accessible places.

there may be occasions when torque tightening of a screwed joint must be followed by angle tightening and space does not allow the use of protractor 9512050 . Use a nut, screw head or tools in such cases.

The nut, screw head or tools is often 6 edged and each corner of the nut, screw head or tool corresponds to 60° . A 12 edge corresponds to 30° at each corner etc.

angle tightening is carried out by marking the material and nut, screw head or tool as illustrated and then tightening so that the markings are positioned opposite each other.
