Truncated Setting Plugs
Truncated extra length setting plugs insure more perfect size. Truncated set plug is the same as full-form set
plug except with crest of thread removed for approximately one-half length of gage, giving a full and truncated
portion. The full portion insures correct clearance and forms at major diameter of ring. Truncated portion
controls pitch diameter.
When using truncated setting plug, thread ring gage should be set on the full form of the set plug. The ring
should then be turned on the truncated form, and the “feel” should be the same as on the full form. If there is a
“shake” on the truncated form, this will indicate that the thread form of the ring is unsatisfactory and should
be discarded, or if possible, repaired by relapping.
- Graphitic tool steel for superior quality and longer wear
- Heat treated and cold treated for extreme stability.
- Lapped for extra precision and longer wear.
