In your factory you will be required to make use of NPT thread gauge or Whitworth thread gauge depending on the nature of the threaded components you are manufacturing. Using these thread gauges, you will be checking the accuracy level of the dimensions of the threaded components manufactured. Thread gauge is one of the simplest inspection tools. However, if you are not going to pay attention to some of the most important basics you will not be able to get the correct inspection readings from the tool.
When you are ordering your custom Whitworth thread gauge ask your manufacturer to mark the thread gauges so that you know the size of the tool easily when using them. The markings should be etched on to the thread gauge itself and it should not be just painted because the paint will be peeled off with usage.
All the thread gauges should be stored in their respective protective pouches or cases. The pouches or cases should also be marked clearly. Always store the thread gauges in their respective pouches to avoid confusions when using them. The tool should be used only in the designated work tables. They should not be simply carried around because if they are carelessly handled then the profile of the thread gauge would be damaged and they will not be able to produce accurate readings. Your inspection results will be erroneous.
Never drop the thread gauges and that is why it important to use them in the designated work tables. This will reduce the chances of the tool being dropped. The tool should be replaced regularly based on the wear and tear experienced. You should not continue using a worn-out thread gauge because you will not be able to inspect the thread components correctly with a worn-out tool.
Cleaning and maintenance protocols should be followed. The thread gauges should be cleaned regularly before and after use without fail. The bur or the small metal particles will be deposited during use on the thread gauge profile. If they are not carefully cleaned when you continue to use the tool it will damage the thread gauge as well as the component that you are inspecting.
The thread gauge should not be stored with oil deposits. If you are checking a freshly tapped threaded components, they will have lubricant deposits and these lubricants if not cleaned immediately it could have a corrosive effect on the thread gauges and damage the profile of the thread gauge.
The person using the thread gauge should be given adequate orientation because if they do not now how to use the tool, they could actually damage the tool. Undue force should not be exerted when checking the threaded components. The moment the thread tightens it has to be stopped. You should be able to loosen the thread gauge from the component with minimal force using your hand without any need to use for a tool. All these efforts will help you get the most out of your thread gauges.
