A mounting device (10) is shown particularly adapted for adjustably mounting vectorless test heads for circuit board components and the like to be tested for processing faults of component pin connections with traces of a circuit board in which the components are mounted. A U-shaped bracket (18) is lockably received on a rail (2) and has first and second projections (18d,18e) slidably received through a respective slot (16c,16d) of a leg (16) of a T-shaped member (12). The base leg (14) of the T-shaped member (12) is connected to one end of a pin member (24) which slides through a bore (18p) in one arm (18b) of U-shaped bracket (18) and is threadingly received in a threaded bore (18n) of the other arm (18a) of the U-shaped bracket (18). Rotational movement of the pin member (24) causes T-shaped member (12) to move in a Z direction to permit precise locating of a test head (30) mounted on the base leg (14). The mounting device (10) is also shown mounted on a resinous mounting plate (40) having a plurality of sets (40a) of mounting apertures.
