M6*0.75-6H precision measuring instrument

High-precision measurement

High accuracy: The M6*0.75-6H gauge adopts a high-precision manufacturing process, which can accurately measure the size and shape of the internal thread and ensure the accuracy of the measurement results.

Compliance with standards: Following the international standard ANSI/ASME B1.16M, the reliability and consistency of the gauge are guaranteed.

High-quality materials and durability

High-quality materials: Usually made of high-quality materials such as high-speed steel (HSS), it has good hardness and wear resistance, and extends the service life.

Hardening treatment: After hardening treatment, the hardness can reach 64HrC, ensuring that high accuracy can be maintained under frequent use.


Product Details

About the product


This M6*0.75-6H gauge is a high-precision tool designed for accurate measurement of internal threads. It is made of high-quality materials to ensure the durability of the product and the accuracy of measurement. The design of the gauge meets international standards and is suitable for a variety of industrial application scenarios, such as machining, automotive parts manufacturing, etc. It is easy to operate and easy to read the measurement results, which can effectively improve work efficiency. At the same time, the product also provides a professional calibration certificate to ensure the reliability of the measurement results.


Material & Construction

  • Gauge Body: Crafted from high-grade tool steel (SUJ2 or 1.3505) with heat treatment to 58–62 HRC. This material delivers exceptional wear resistance—critical for maintaining thread profile accuracy after repeated use—and resistance to corrosion in workshop environments.

  • Thread Profile: Precision-ground using CNC thread grinding machines, ensuring strict adherence to the 6H internal thread tolerance class (per ISO 898-1). The thread flanks, pitch (0.75mm), and major/minor diameters are machined to ±0.002mm tolerance for reliable measurement.

  • Surface Treatment: Optional black oxide or passivation coating to enhance rust resistance, extending lifespan in humid or coolant-exposed settings (e.g., automotive part inspection stations).

Correct operation method of M6*0.75-6H gauge:

Preparation before operation

Inspect the gauge: Before use, check whether the gauge is intact and ensure that there are no defects such as rust, wear or scratches on its surface.

Calibrate the gauge: Before use, the zero position of the gauge should be calibrated, the error value should be determined and the correction amount should be remembered so that correction can be made when reading.

Clean the gauge and workpiece: Clean the oil, impurities, burrs, etc. on the surface of the gauge and the measured workpiece to ensure the accuracy of the measurement.

Operation steps

Thread plug gauge

Choose a suitable gauge: According to the specifications of the measured thread, select a matching M6*0.75-6H gauge.

Align the thread: Align the through end (GO) or stop end (NO-GO) of the gauge with the measured thread to ensure that the two are coaxial.

Rotate the gauge: Use your thumb and index finger to gently turn the gauge or the measured part to rotate in a free state. Normally, the through end should be screwed in smoothly at any position of the measured thread and pass through the entire thread length; the stop end is qualified if it is screwed into the thread length within 2 pitches.

Reading results: Determine whether the thread is qualified based on the matching of the measuring tool and the measured thread. If the through end can pass smoothly and the stop end stops within the specified pitch, the measured thread is qualified.

Withdrawing the measuring tool: When withdrawing the measuring tool, it should rotate naturally and smoothly to avoid excessive force or skewness.

Precautions

Thread plug gauge

Operation force: During the measurement process, avoid excessive or too light force to avoid inaccurate measurement results.

Keep the measuring tool dry: The measuring tool should be kept dry and avoid using or storing it in a humid environment to avoid affecting the measurement accuracy.

Regular maintenance: Clean the stains on the measuring tool in time after use, and store it properly in a dry and ventilated place to avoid mixing with other tools.

Environmental conditions: Try to use and store the measuring tool at room temperature (15-25℃), and avoid placing it in high or low temperature environment for a long time to avoid affecting the measurement accuracy.

Thread plug gauge

Applications

  • Target Industries & Uses:

    • Machining: Inspecting internal threads in milled/turned parts (e.g., threaded holes in aluminum brackets).

    • Automotive: Verifying threads in engine components (e.g., sensor mounts), transmission parts, or chassis fasteners.

    • Electronics: Checking small threaded holes in device housings (e.g., smartphone case mounting points).

    • Aerospace: Ensuring thread accuracy in lightweight alloy components (e.g., aircraft interior brackets) where loose fasteners pose safety risks.

  • Key Task: Quality control (QC) during production, incoming inspection of parts, or maintenance verification of threaded components.
