Plain Plug Gauges.

What are Plain Plug Gauges?

Plain Plug Gauges are precision tools used to verify the dimensional accuracy of drilled or machined holes. Inserted into holes, these cylindrical gauges ensure diameters meet specified tolerances. Using a gauge engineers can confirm components fit together seamlessly, crucial for quality control in manufacturing where exact measurements are vital.

How Plain Plug Gauges Work

Plain Plug Gauges work on the Go/No-Go principle. The "Go" end fits into a hole if it meets the minimum size; the "No-Go" end shouldn't fit if the hole exceeds the maximum size limit. This allows quick, accurate assessments of hole diameters. Industries like aerospace, automotive, and precision engineering use Plug Gauges to ensure components meet strict dimensions, preventing assembly issues and enhancing performance.

Materials Plain Plug Gauges are Made From

Our Plain Plug Gauges are made from hardened steel, providing exceptional durability and resistance to wear. This ensures the gauges maintain precise dimensions even after repeated use, offering consistent accuracy over time. The robust material is ideal for demanding industrial environments where reliability and longevity are essential.

Size and Types of Plain Plug Gauges Available

We offer Plain Plug Gauges ranging from 2mm to 100mm, accommodating various applications. Each gauge meets the H7 tolerance class, with Go tolerances of +0.0005mm to +0.008mm and No-Go tolerances of +0.009mm to +0.011mm. All gauges come with a Certificate of Conformity. Our Precision Plain Plug Gauges provide the accuracy required for high-quality workmanship.

FAQ

Q: What is a Plain Plug Gauge?

A: Plain Plug Gauge is a precision tool used to check the diameter of drilled or machined holes. It is cylindrical with exact dimensions to verify if a hole meets specified tolerances. By inserting it into the hole, you can quickly determine if the size is acceptable.

Q: How Do You Calculate Plain Plug Gauge Tolerance?

A: Plain Plug Gauge tolerance is calculated based on the acceptable deviation from the nominal hole size, defined by tolerance classes like H7. For example, a Go gauge may have a tolerance of +0.0005mm to +0.008mm, while a No-Go gauge has +0.009mm to +0.011mm. These tolerances ensure the gauge accurately reflects whether a hole's diameter is within limits.

Q: How Accurate is a Plug Gauge?

A: Plug gauges are highly accurate, often with tolerances within a few micrometers. Their accuracy depends on manufacturing quality and adherence to industry standards. Our Gauges meet stringent tolerance classes like H7 for critical measurement tasks.
