Types of Thread Gauges
Thread gauges come in various types, each designed for specific measurement purposes. Here are some common types of thread gauges:
- Thread plug gauges: Used to measure screw threads and calibrate gauges. They come in various types, including tapered pipe thread gauges and thread snap gauges.
- Thread ring gauges: Used to check the external threads of screws and bolts. They are also used to calibrate gauges.
- Special thread gauges: Used for specific types of threads, such as pre-plates, multiple starts, special leads, acme thread gauges, and API thread gauges.
- Taper gauges: Used to measure the taper of a hole or slot.
- Snap gauges: Used to measure the thickness of a part or the distance between two surfaces.
- Feeler gauges: Used to measure the gap between two parts.
- Form gauges: Used to measure the shape of a part, such as the contour of a gear tooth.
- Caliper gauges: Used to measure the distance between two points on a part.
Thread gauges are primarily used in production shops for acceptance gauging of threaded parts. However, there are other thread gauges used mostly in the Standards Room for checking and calibration of the aforesaid thread gauges.
Thread Plug Gages and Ring Gages
Thread plug gages and ring gages are both used for dimensional measurement, but they differ in their usage. Here are some key points about thread plug gages:
- Used to check internal threads
- Comprises of two parts: a GO and a NoGo gauge
- The GO thread plug gage inspects the minimum major diameter and the minimum pitch diameter size in a threaded part, while the NoGo thread plug gage inspects to ensure the threaded hole does not exceed the maximum pitch diameter size in a threaded part
- The "three-wire method" is used to measure thread pitch diameter for thread plug and thread setting plug gages
- Plain plug gauges are used to check the dimensional tolerances on holes that are bored or drilled with smooth walls, while threaded plug gauges 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
And here are some key points about thread ring gages:
- Used to check internal threads (Editor's comment: Correction needed. Thread ring gages are used to check internal threads.)
- Comprises of a single ring gauge
Recommended Models of Thread Gauges
Based on individual requirements, here are some recommended models of thread gauges:
- Gagemaker Thread Gages: Offered by Thread Check, a proud authorized distributor of Gagemaker. These thread gauges can be purchased from Thread Check.
- Thread Functional Size Gages: Manufactured by Gagemaker, these gauges inspect the cumulative effects of the thread elements including diameter, lead, taper, flank angle, and form error. They can be purchased from Thread Check.
- Functional Size Gages by Gagemaker: These functional size inspection (or “GO/NO GO”) gauges measure external thread diameters ranging from â �” – 24â�³. They can be purchased from Gagemaker.
- 3-Wire Thread Measuring System: The External Supermicrometer Model C is the industry standard, 3-Wire Thread Measuring System. It can be used to measure the pitch diameter of external threads up to 1.5 inches in diameter. This system is manufactured by Pratt & Whitney and can be purchased from their website.
- Dimensional Gages and Instruments: There are many types of dimensional gages and instruments that include specialized devices that measure thickness, thread size, pitch, serration, and other parameters. These gages can be purchased from various manufacturers and suppliers.
Please consider your individual requirements when selecting a thread gauge. Factors such as the type of thread being measured, the diameter of the thread, and the accuracy required should be taken into account.
Ring Gauges for Dimensional Tolerance
Ring gauges are used to ensure that the gauged part falls within the specified dimensional tolerance. They are typically cylindrical in shape and are fabricated from a stable material, usually tool steel, with a highly precise bore.
The dimensional and geometric tolerances for cylindrical ring gauges are defined by the ASME B89.1.6 standard in the United States.
The standard defines the tolerance grades for ring gauges in metric and English dimensions for master, setting, or working applications.
Thread Pitch Gauges for Measuring Thread Pitch
Thread pitch gauges are tools used to measure the pitch or lead of a screw thread. They are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole. There are different types and sizes of thread pitch gauges available for industrial measurement:
- Metric Thread Pitch Gauge: Used to measure the pitch of metric threads. It typically contains a range of pitches from 0.25mm to 6mm.
- SAE Thread Pitch Gauge: Used to measure the pitch of SAE threads. It typically contains a range of pitches from 4 to 42.
- Whitworth Thread Pitch Gauge: Used to measure the pitch of Whitworth threads. It typically contains a range of pitches from 4 to 12.
- Thread Measuring Gage: Used to measure the pitch of metric screw threads. It typically contains a range of pitches from 0.5mm to 7mm.
Thread pitch gauges are designed to determine the gradient for external and internal threads. To use a thread gauge, the user must first match the type of thread to the gauge. Once the correct gauge is determined, the user should extend one of the leaves of the tool and press it against the threaded portion.
Snap Gauges for Quick Dimensional Verification
Snap gauges are a type of limit gauge used to quickly verify whether an outside dimension of a part matches a preset dimension or falls within predefined tolerances. Here are some ways in which snap gauges differ from other types of gauges:
- Function: Snap gauges perform assessments on the outside diameters of parts, similar to other tools and measurement instruments such as ring gauges and thickness gauges. However, snap gauges can be used for checking dimensions on both cylindrical and non-cylindrical parts, whereas ring gauges are for cylindrical parts only.
- Go/No-Go: Snap gauges are usually go/no-go gauges, meaning that a single gauge has the capability to assess both the upper tolerance limit on the dimensional parameter being measured as well as the lower tolerance limit.
- Types: Snap gauges can be characterized as being of several different types. Broadly speaking, there are fixed snap gauges and adjustable snap gauges. Fixed snap gauges have jaws with two different measurement widths, with the go gauge set to the high limit of the shaft or part dimension and the no-go dimension set to the lower or minimum limit value. Adjustable snap gauges have movable anvils that may be adjusted over a limited range of sizes.
Snap gauges are used in production settings where specific diametrical or thickness measurements must be repeated frequently with precision and accuracy. They are most frequently used in production environments where precise diameter or thickness measurements need to be made quickly and efficiently. Snap gauges facilitate making interchangeable parts and have been in existence since at least 1898. They are often calibrated by skilled workers and used by machinists, quality control personnel, and inspectors.
Choosing the Right Thread Gauge
When choosing a thread gauge, it's essential to consider your specific requirements. Here are three possible customers and the best thread gauge for each of them:
- Customer 1: A production shop owner who needs to measure screw threads and calibrate gauges. The best thread gauge for this customer would be Thread Check, as they offer a line of custom gauges and thread ring gages specifically designed for these purposes.
- Customer 2: A machinist who frequently works with metric screw threads. The best thread gauge for this customer would be a metric thread pitch gauge, as it allows for precise measurement of the pitch of metric threads.
- Customer 3: A quality control personnel who needs to quickly verify whether an outside dimension of a part matches a preset dimension or falls within predefined tolerances. The best thread gauge for this customer would be a snap gauge, as it provides a quick and efficient way to check dimensions on both cylindrical and non-cylindrical parts.
Remember to always consider factors such as the type of thread being measured, the diameter of the thread, and the required accuracy when selecting a thread gauge. By choosing the right thread gauge, you can ensure accurate and precise dimensional measurement in your work.
