A screw THREAD, is a ridge of uniform section in the form of a helix on the external or internal surface of a cylinder,
or in the form of a conical spiral on the external or internal surface of a cone or frustum of a cone.
A thread formed on a cylinder is known as a “straight” or “parallel” thread, to distinguish it from a “taper”
thread which is formed on a cone or frustum of a cone. Union Technologies will share about the thread checking,
gauge using and maintance, to ensure apply your thread measurement correctly.
