Adjustable parallels have a wide range of uses in layout, gaging, inspection work and for setups on various machine tools. Their adjustable feature makes it possible to adjust them to exact size by micrometer measurements and also permits use in place of several solid type parallels. These parallels are useful as gages in checking the size of slots and openings. They can be quickly inserted in openings and expanded to size. The size of the hole can then be determined by measuring the parallels externally with a micrometer. They are also convenient for use in machine vises, for leveling up or adjusting work on setups of milling and grinding machines, shapers, planers, drill presses and for many other applications.
