Reversible trilock thread plug gages are used to check the size of internal threads to ensure the threads are within its designed tolerance limits. The reversible trilock plug gage design is best suited for large size thread plug gages (1-1/2 inches and up), but is available in sizes as small as 3/4 inch. Consisting of a GO and/or NOGO member(s), the trilock has a bolt fastening system to support the size and weight. A chip groove is provided on the Go member for ease of identification and clearing obstructions.

Reversible trilock thread plug gages are manufactured in Class X tolerance and made in full conformance to ASME/ANSI B1.2 . Reversible trilock thread plugs can also be reversed on the handle resulting in a longer wear life. Gages ¾” (19.05mm) up to and including 1 ½” (38.1mm) are always assumed taperlock design unless Trilock reversible thread gage is specified when ordered.. WESTport thread plug gages are manufactured to the highest end of the ANSI specifications to ensure the longest gage life possible. Reversible trilock thread plug gages are available in steel and chrome.
