Thread Check, Inc. offers a complete line of AGD – American Gage Design, metric working reversible style thread plug gages. The reversible thread plug gage style allows for one end of the gage to be rotated so the user gets two gages in one. A worn gage end can be turned around by simply opening the collet of the handle and turning the gage and bushing around so the opposite end essentially becomes a new gage. The reversible thread plug gage is ideal in high volume inspection applications. Thread Check’s reversible thread plug gages are manufactured per ANSI/ASME B1.16M. Thread Check, Inc. reversible style thread plug gages are manufactured to an X tolerance in class 6H. Reversible thread plug gages are available in M, MJ and specials. All standard reversible thread plug gages are stocked in hard chrome coating which extends the wear life of the gage by more than a 100% thus providing dramatic savings in replacement costs. All Thread Check, Inc. gages are manufactured to the high end of the tolerance to ensure longer gage life. Thread Check, Inc. manufactures reversible thread plug gages in carbide, ceramic and other types of specialty steels. Thread Check manufactures many types of special gages including pre-plates, multiple starts, special leads, acme threads, buttress threads, square threads, extra length thread gages, and custom gages to print.
