Product Description Customized high precision measurement tools manufactured thread plugPlug gauges come in several styles or configurations making them suitable for different uses. Plain plug gauges are used to check the dimensional tolerances on holes that are bored or drilled with smooth walls. There are also threaded plug gauges that are used to check threaded or tapped holes, and verify the proper thread type, major diameter, minor diameter, pitch diameter, and pitch of the thread against a mating thread gauge.As with ring gauges, some plug gauges called master sets or master plugs are not used as working gauges but are instead employed to validate other measuring instruments such as bore gauges or external micrometers, for example, by providing a measurement standard or reference standard for calibration purposes. The practice is known as indirect gaging.Other Plug gauge styles also include the following:Wear recognition plug gauges that feature a black oxide coating that will show wear patterns as the tool is utilized, making it easier to establish when the tool needs to be replacedPlug gauge sets, wherein a wide range of gauge sizes are offered in a case or cabinetTarget-size plug gauges that allow the user to specify a target size and gauge type (go or no-go) and receive a kit that contains the target size gauge plus 12 larger and 12 smaller gauges, each varying by 0.0001 of an inch in each step up or down. These are also known as tenth-step gauges.Threaded plug gauges for NPT pipe threads allow the user to verify the internal threads on threaded pipe couplings.Thread gauge handles that allow the user to interchange gauge sizes.Plug gauges are typically fabricated using high-grade tool steel such as 52100. This choice provides both corrosion resistance due to the high chromium content of the steel and a reduction in friction during use, which helps to extend the life of the gauge.Tungsten carbide gauges offer high wear resistance, some 50x that of tool steel. In addition, it is non-magnetic, somewhat resistant to corrosion, and will not burr. Tungsten carbide does, however, have a low coefficient of thermal expansion, and so more stringent temperature control is warranted when using tools of this material to gage steel parts of tight tolerance.Chrome-plated plug gauges will also provide a harder surface and can be used for the gaging of abrasive materials such as magnesium or aluminum.
