Screw thread and Gear measurement Screw thread measurement: Elements of measurementerrors in screw threads-measurement of effective It is the value obtained by subtracting the design tooth /5(3). For precise thread measurements with wire, the measuring wire deformation needs to be taken into account as the pressure can compress it. On a micrometer screw with a measure pressure of 10 Newton, the pressure of the wire is mm. on a M20 thread and mm on a M60 thread. Screw thread measurement pdf Measurement of major diameter, minor diameter, pitch, angle and effective diameter of screw threads by 2-wire and 3-wire methods, best size wire. screw thread measurement ppt download A SCREW THREAD is a ridge of uniform section in the form of a.
