Screwed joint, torque/angle tightening
There are a great number of torque spanner systems available on the market where the spanner grip can be replaced with other types. These wench grips are normally ideally suited to 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 (part number 9512050 ). In these cases, use either a nut, a screw head or a tool. These are usually hexagonal and each corner is 60° . If there are twelve edges, each corner is 30° .
To angle tighten, mark the material and nut for example as illustrated and then tighten so that the markings are opposite each other.
