GAGEMAKER
TAS-1014 Thread Addendum 8 & 10 Rd Standard per API SPEC 5B.
Per API 5B 5.5.2, Thread addendum “shall be measured on round thread.”
TA-3002 Thread Addendum Gage Inspecting a Part Thread addendum is now a required, mandatory element to be inspected.
Inspection should be done with an indicator style gage with contact points, like our TA-30002 Thread Addendum Gage.
Choose a contact point based on the Threads Per Inch (TPI). In Table 20, 5B provides the options for you:
Threads Per Inch (TPI) | Contact Point Diameter | Gagemaker Model Number |
8 | 0.072″/1.83mm | T072 |
10 | .0057″/1.45mm | T057 |
Note: Tolerance is 0.002 in/ 0.05mm
Set the gage with the proper standard. For both 8 and 10 Round threads, Gagemaker separately offers the TAS-1014 addendum standard for use with any of its addendum gages
