Thread plug gauges – The types and features you wanted to know!

It was about a month ago when I was in need of thread plug gauges for my company. Being perplexed about the right gauges to suit my organization’s needs, I got in touch with an old friend of mine who suggested me to use the plug gauges. Though he runs a different type of business, I took his advice by heart and guess what, plug gauges did wonders!

These threading plug gauges are used for checking the internal threaded hole. These are used to test parts which have closer tolerance necessities. Thus, these gauges have the capability to suit your company’s needs!

Are you still half-convinced? Well, read on then, and you will echo the same thoughts!

What are plug gauges?

These thread gauges are basically used for checking the interior threaded part of a nut.  Further, these are used for measuring the accuracy of a pitch diameter. While using these gauges for bigger purposes, one needs to make use of the double ended plug gauges.

Styles of working thread plug gauges

  1. Taperlock

This style consists of both the GO and NO-GO members. As compared to the NO-GO member, the GO is longer and has chip grooves of larger sizes which add ease of identification and assist in getting rid of obstructions.

  1. Trilock

Though these are best suited for plug gauges of larger sizes which are more than 1-1/2 inches, these are even available in small sizes of ¾ inches. Along with the GO and NO-GO members, it even consists of a bolt fastening system to support the weight and size.

  • Reversible

Just like its other two counterparts, reversible gauge too consists of NO-GO and GO members. These assure you of maximum durability by reversing the worn out portion of the gauge member into the handle.

Features of thread plug gauges

  • GO Gauge

These provide an accuracy tool for producing comparative gauging which is based on a pre-determined limit. These gauges comprise of a specific limit gauge with a limit as per the plus or minus tolerance of the part which has been inspected. Its dimensions are based on the lowest value of ID tolerance of the gauged part or the internal hole. This should be in particular to a plus gauge maker’s tolerance from the lowest part tolerance.

  • NO-GO Gauge

Just like the GO gauges, these NO-GO gauges too prove to be a precision tool for producing relative gauging as per a specified limit. However, the dimensions of a NO-GO gauge are based on the highest value of ID tolerance of the part or hole which has been gauged. This needs to be in particular to a minus gauge maker’s tolerance from the highest part tolerance.

  • GO / NO-GO Double end gauge

These gauges with double ends consist of a NO-GO gage pin on one end and the GO gage pin on another side. Such gauges offer an accurate tool for producing proportional gauging which is based on specific limits. These consist of a specific limit gauge with two limits which are based on the plus/minus tolerances of the part inspected.

Now that I have shared with you the details about these thread gauges, what are you still waiting for? Hurry up and visit a reputed online gauge supplier. Time to get hold of your plug gauges!
