Metric thread included angle

WebThe main difference is that the thread profile is tapered at an angle of 1°47′ (0.75 in/ft or 62.5 mm/m) relative to the axis. The taper on NPT threads allows them to form a seal when torqued as the flanks of the external and internal threads compress against each other (no clearance remains between the crests and roots of the threads because of the taper). WebTo measure the effective diameter of an external metric thread included angle is 60∘ of 3.5 mm pitch, a cylindrical standard of 30.5 mm diameter and two wires of 2mm diameter each are used. The micrometer reading over the standard and over the wires are 16.532 mm and 15.398 mm respectively. The effective diameter in mm of the thread is Question
