Thread form accuracy is important if two connections are to make-up properly. Using a Thread Profile Gage is a quick way to check your threads for proper form and pitch.

Thread form is defined as its profile in an axial plane for a length of one pitch. Simply place the correct form into the threads and by shining a light behind the profile, it’s possible to detect any signs or symptoms of a chipped insert. A profile template that stands too far out of the threads or allows excess light to shine through can be an indication of lead error. Sweeping the profile template along the helix of the threads helps find burrs and debris. Profile gages can also be be used to detect steps, flat crested threads, stretched threads, wide first threads, or rolled over threads.

Verifying thread form is a highly recommended practice industry wide for both straight and tapered thread manufacturers.
