1.)ACME THREAD GAUGE – A gauge used for checking and testing the 29° angle and the width at the end of a thread cutting tool while grinding it.It is also used for setting the tool square with the axis of the workpiece.
2.)DEPTH GAUGE – Gauge used for the purpose of measuring the distance between two surfaces, to find or check the depth of a counterbored hole, a recess etc.
3.)DIAL GAUGE – Instrument indicating the movement of a projecting plunger by the movement of a hand or pointer over a graduated dial.
4.)ENGINEERS TAPERS– are intended for measuring hole sizes, slot widths, caliper settings and so on.
5.)FEELER GAUGES– Consist of a number of thin metal blades, each of a different thickness and in the desired number of dimensional steps.They are used for checking clearances.
6.)HERMOPHRODITE CALIPER – A caliper having one leg similar to that of an inside caliper, while the other leg is pointed like a divider leg.
7.)HOOK RULE – A steel rule with a projecting piece or hook at one end at right angles to the edge of the rule.
