Gauging head and apparatus for linear dimension checking of mechanical pieces comprising an integral element that defines an arm carrying a feeler, a reference portion, and a fulcrum that enables rotations of the arm with respect to the reference portion, and a differential transformer position transducer with a cylindrical shaped casing, carrying windings, fixed to the reference portion, and a ferromagnetic core movable together with the arm. The integral element is locked in an adjustable way to a support by means of the cylindrical casing. The integral fulcrum is achieved by work hardening the material and subsequently grinding it.
