1.	Thread measurement with inserts fitted in the anvil and spindle of screw tread micrare selected on the basis of one the following elements of a thread being measureda) Major diameterb) Minor diameterc) Effective diameterd) Pitch
Answer» An external thread is determined by the outside diameter, pitches and thread angles. A slide gauge measures the outside diameter, and a screw pitch gauge measures the pitch and controls the thread angle. Measuring the internal thread is difficult as a slide gauge also measures the inside diameter, however, the thread angle cannot be determined. Likewise, the screw pitch gauge cannot accurately determine the pitch. Measuring threads can be difficult, especially the internal thread. Often, tools are used such as the thread plug gauge for the internal measuring and a thread ring gauge or a thread pitch gauge for the external thread measuring. a, d are the answers

Answer»

An external thread is determined by the outside diameter, pitches and thread angles.

A slide gauge measures the outside diameter, and a screw pitch gauge measures the pitch and controls the thread angle.

Measuring the internal thread is difficult as a slide gauge also measures the inside diameter, however, the thread angle cannot be determined. Likewise, the screw pitch gauge cannot accurately determine the pitch.

Measuring threads can be difficult, especially the internal thread. Often, tools are used such as the thread plug gauge for the internal measuring and a thread ring gauge or a thread pitch gauge for the external thread measuring.
