Thread Height Inspection-External Thread Height Gauges
Proper Thread Height maximizes the performance of the connection. Thread height inspection is an API requirement. FYOU PMEC thread height gages inspect external or internal thread height for a variety of thread forms. A shallow thread height may allow the connection to pull apart under stress.
FYOU PMEC supply many models of external thread height gages. Specify the type of thread when ordering.For tubing and casing, standards may be required
