Metric Thread Plug Gages - Taperlock Design - Carbide

Thread Check, Inc. offers a complete line of AGD ‐ American Gage Design, unified working taperlock thread plug gages in carbide for greater wear resistance and longer life. Carbide thread plug gages are ideal for high volume and 100% inspection. The taperlock thread plug gage style allows for a quick and convenient replacement of the gage member into an existing handle. When the carbide thread plug gage eventually wears, the gage member can be simply removed, and a new replacement inserted into the handle.

Thread Check’s taperlock carbide thread plug gages are manufactured per ANSI/ASME B1.2. Thread Check, Inc. taperlock carbide thread plug gages are manufactured to an X tolerance in class 2B or 3B. Taperlock thread plug gages are available in UNC, UNF, UNEF, J and specials.

All standard taperlock carbide thread plug gages ship in 5-6 weeks. All Thread Check, Inc. gages are manufactured to the high end of the tolerance to ensure longer gage life. Thread Check, Inc. also manufactures taperlock thread plug gages in 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. All thread plug gages are traceable to N.I.S.T.
