Calipers are one of the oldest type of comparison measuring tools. These are designed for taking comparative 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.
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. An Alternative to the solid adjusting nut, a split quick adjusting nut is also available which helps in making quick & positive adjustments.
The threads of the nut firmly engage the screw at the slightest pressure of the leg. When the pressure is withdrawn, the nut releases itself sliding freely over the screw. This feature helps save time in opening and closing when a variety of measurements have to be taken consecutively.
