Calipers are one of the oldest type of comparison measuting tools. These are designed for taking comparitive measurements and transferring the dimensions to a micrometer, precision rule etc.
Dividers are used for marking out circles on steel or transferring measurement from master templates
Manufactured from selected steel, calipers and dividers have a spring joint for precision settings. The legs pivot on a roller and are tensioned by bow spring. The fulcrum stud has a large bearing surface that prevents side deflection of legs
Adjustment is made by opening and closing of the legs by means of an adjusting nut
Divider points are hardened 50-55 HRC for increased wear resistance
