Those employed in the mechanical and technical fields are undoubtedly aware of the significance of thread gauges. Numerous engineers and mechanics view the thread gauge as a focus point due to the fact that this small-appearing tool is capable of measuring screws and bolts with great precision.
Nevertheless, you must also consider the type of thread gauge that would be ideal for measuring the particular assortment of screws or bolts you have in hand. Below are the three most commonly encountered kinds. So, be careful.
- Ring Gauge
The ring gauge is a common variation used to determine thread pitches. These gauges are available in individual parts with differing sizes. These measuring instruments are suitable in measurement of male screws.
The greatest benefit of the thread ring gauge is its ability to precisely measure the thickness of a screw. Furthermore, this thread gauge measures the diameter and pitch of the screw with equal precision. Hence, it measures the screw thread with greater precision than with the blade gauge. Additionally, bespoke ring sizes and gauge designs are available upon request.
Limitations: The biggest drawback of this ring gauge is that you cannot utilize trial and error to reach a conclusion while measuring a thread with it. Consequently, it can be stated that the ring gauge is less adaptable than the sheet gauge. Hence, if you are required to measure multiple thread sizes, you should have a nearly equivalent number of adjustable diameter ring gauges.
- Leaf Gauge
The leaf gauge is perhaps the most prevalent form of the thread gauge in the engineering business. The most distinguishing characteristic of this caliber is its appearance. Accordingly, upon first glimpse, this caliber variant will resemble a Swiss Army Knife.
The main advantage of Leaf Gauge is how it provides multiple measurement choices in a single instrument. Because the blade indication consists of numerous blades installed on a unified platform, this is the case. Therefore, if a screw’s thread size must be determined by trial and error, there is always a blade with a distinct tooth pitch available to facilitate the process.
Limitation: Due to its blade-like form, this gauge version cannot accurately measure the whole diameter of a screw or even a bolt.
- Plug Gauge
In addition to the above two types of thread gauges, you will also find thread plug gauge, which are utilized for specialized reasons due to their unique benefits. These type of gages are used to inspect the tolerances of threaded parts in agreement with a standard configuration. These very particular calibration instruments can be used to guarantee the assembling of mating parts as well as quality control and standard compliance. Most will have two options i.e. go or no go. The go side must be completely screwed on, whereas the no go side must remain the way it is. For each gage, the class of fit estimates the estimates of tolerance allowable for that class.
