Metric Plug Thread Gauges.

What are Metric Plug Thread Gauges?

Metric Plug Thread Gauges are precision tools designed to inspect and verify the accuracy of internal threads made to metric standards. These gauges feature external threads precisely crafted to match the required metric thread dimensions, including pitch and diameter. They ensure that tapped holes and nuts meet strict tolerances, guaranteeing reliable and secure connections when paired with mating components.

How Metric Plug Thread Gauges Work.

Metric Plug Thread Gauges are used to assess the quality of internal threads by threading the gauge into the component. A "Go" gauge verifies that the thread meets the minimum size requirement by fitting smoothly without excessive force, while a "No-Go" gauge ensures the thread does not exceed the maximum allowable tolerance by failing to engage fully. This dual-check system is essential for quality control in industries such as automotive, aerospace and manufacturing, where precision and reliability are paramount. For instance, these gauges are commonly used in the production of engine components, ensuring tapped holes are perfectly threaded to accept bolts securely.

What Material Metric Plug Thread Gauges are Made From.

Metric Plug Thread Gauges are typically manufactured from hardened tool steel or high-grade alloy steel. These materials are chosen for their durability, wear resistance and ability to maintain dimensional accuracy over repeated use. 

What Size and Type Metric Plug Thread Gauges are Available.

Metric Plug Thread Gauges are available in a wide range of sizes, accommodating both coarse and fine metric thread profiles. Standard sizes cover diameters from M1 to M100, with corresponding thread pitches to suit various applications. Both "Go" and "No-Go" gauges are essential for thorough inspection, ensuring internal threads meet both minimum and maximum tolerances. Each gauge is precision-engineered to deliver consistent, repeatable results, making them indispensable for quality assurance in high-precision engineering tasks.

FAQs.

Q: What is the purpose of Metric Plug Thread Gauges?.

A: These gauges ensure that internal threads conform to metric standards, guaranteeing secure and reliable connections in threaded assemblies.

Q: What is the difference between coarse and fine metric threads?.

A: Coarse threads have a larger pitch for quicker assembly and greater strength, while fine threads provide tighter fits and are used for precision applications.

Q: How often should Metric Plug Thread Gauges be calibrated?.

A: Regular calibration is recommended to maintain accuracy, especially for gauges used frequently or in critical applications.
