CUBEX BUTTRESS
The TP Series of Tapered Thread Profile Gages are manufactured to tolerances of +.0002”, using EDM technology. These precision gages are ideal for quickly identifying each of the different tapered thread forms named in the API Std. 5B and Specification 7. Thread profile gages can also be used to perform a visual inspection of a thread form for detecting chipped inserts, stretched threads, wide first threads, or rolled over threads. Special profiles are available and quoted upon request.
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.
