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.
