Screw Gauge

    Screw Gauge with stainless steel spindle and ratchet top brass body with satin chrome finish.Brass, semi-circular body with stainless-steel screw that remains entirely unexposed and moved smoothly. screw pitch gauge also known as a micrometer is a precision instrument. It is used for measuring diameter of circular objects mostly wires, with an accuracy of 0.001cm. It consists of a hollow cylinder mounted on a U frame. The hollow cylinder leads to a ratchet which is meant for fine adjustment. The U frame consists of a flat end known as stud and a screw on the other side. This screw can be moved inside the nut by fitted in the U frame by rotating the hollow cylinder called the thimble. This is called the main scale. The hollow cylinder or the thimble is graduated into 50 or 100 equal parts. This is called the circular scale.

    Screw gauge or micrometer screw gauge is a measuring instrument used for precision measurement. A measuring device used extensively in the mechanical engineering field, micrometer screw gauge is used for measuring extremely small dimensions. A screw gauge can even measure dimensions smaller than those measured by a Vernier Caliper. Belonging to the family of calipers, micrometer screw gauges also consists of two different scales.
