What to Know About Thread Gauges

Thread gauges are metal tools that are typically used to ensure that pipe fittings, nuts and screws work properly before completing the pieces. Try these ideas to use and care for these gauges while completing your work.

Checking Nuts? Use a Plug Gauge

Plug gauges typically check the ability of the nut to accomodate screws of a certain size by helping you to check the pitch diameter of the nut. When you use one of these gauges, it has a GO end and a NO-GO end. The GO end should be able to screw into a nut easily and without force in order for the nut to be deemed usable. Conversely, the NO-GO end of the same plug gauge should not be able to screw in at all.

Are you checking out the thread count of a screw to ensure that it has the proper turns per inch (TPI)? In that case you'll want to use a regular ring gauge.

Handle Gauges with Care

Whatever kinds of gauges you use, it's important that you keep them in good shape so that you can be sure they function effectively. Before storing them away, consider using oil-based wax or another sealant to ensure that they don't rust during the time you're not using them. In addition, you might want to purchase a master thread gauge in order to periodically test the rest of your gauges and to ensure that they aren't worn down.

You'll Need to Have Extra Gauges

You might also want to have a variety of thread gauges and plug gauges around your shop so that you are never without them when working on different kinds of metal pieces. Having extras nearby is particularly helpful because screws and nuts are small pieces and so are the gauges; they can typically be held in the hand. That makes them easy to drop and lose when you're not paying attention. Needing to delay work because you cannot locate the proper gauges is not going to be appreciated by employees or clients, so be sure that you always buy more than you think you'll need.

Now that you have a clearer understanding of gauges and how they could fit into your day to day work, talk with an industrial supplier about which gauges may be right for you. They can offer you additional information that is relevant for the particular projects you work on. For more information, contact a business such as West Port Corp.
