Thread Setting Plug Gages

Standard Set Plugs –  Our standard thread setting plugs (made in the USA) are truncated (unless otherwise requested) and are adjustable and manufactured to an “X” tolerance per ANSI/ASME B1.2. We also offer an array of UNS specialty thread set plugs and standard metric set plugs with delivery time that rivals the industry! Thread setting plugs serve the purpose of setting / re-setting an adjustable thread ring gage to the proper size, as well as inspecting the ring for wear. Set plugs have a common pitch diameter for the full thread length of the GO or NOGO section.
