was ist 6h bei einem gewindelehrdorn?
A clear explanation: 6h denotes a tolerance class for internal threads, defining the allowable deviation for the go/no-go gauge. For professionals it means the go gauge must fit fully while the no-go must not, ensuring conformity to the norm. Used in precision inspection, this rule helps verify whether a threaded hole meets the required size and fit. Manufacturers like Metav IndustryLine supply norm-compliant limit gauges for reliable, repeatable testing.

Understanding what "6h" means for a Thread Go/No-Go Plug Gauge
A Thread Go/No-Go Plug Gauge is a precision inspection tool used to verify internal threads quickly and reliably. When you see the marking 6h applied to a gauge or referenced for a thread, it denotes a specific tolerance position and class according to international thread standards. For professionals in machining and quality control, recognising what 6h stands for is essential to ensure parts fit correctly and meet normative requirements.
What the 6h tolerance position indicates for an internal thread
The 6h designation combines a numerical tolerance grade with a lettered fundamental deviation. The number 6 represents the tolerance grade, which specifies the magnitude of permissible size variation and is commonly used for medium tolerance requirements in threaded parts. The letter h denotes the fundamental deviation for internal threads: it indicates that the internal thread size is referenced without intentional positive deviation, effectively placing the internal thread axis flush with the basic size so that the allowable variation lies only in the negative direction relative to the basic profile. Together, 6h prescribes how tight or loose an internal thread should be made in relation to the nominal size.
How this affects inspection with a Grenzlehrdorn (Go/No-Go Plug Gauge)
A Grenzlehrdorn (Go/No-Go Plug Gauge) works by applying the Go/No-Go principle: the Go plug must fully enter the thread if the internal thread is within tolerance, while the No-Go plug must not enter (or only partially enter) when the thread is out of tolerance. For threads specified as 6h, the gauges are manufactured to the corresponding limits so that:
- The Go gauge verifies that the internal thread is not undersized beyond the lower tolerance limit allowed by the 6h specification.
- The No-Go gauge confirms that the internal thread is not oversized or distorted such that it would exceed the upper tolerance boundary.
This approach enables rapid pass/fail decisions on the shop floor, conserving inspection time and preventing non-conforming parts from progressing further in assembly.
Practical benefits of using the correct 6h gauges in production
Using the properly specified 6h Go/No-Go Plug Gauges brings several important advantages for manufacturing and quality assurance. First, they deliver immediate and unambiguous inspection results, supporting high throughput in serial production. Second, because gauges are made to normative limits, they help maintain interchangeability between mating parts across suppliers and production batches. Third, correctly applied gauges reduce the need for time-consuming dimensional measurements by providing fast go/no-go verification that the internal thread meets the intended tolerance class.
When and why 6h is the right choice for internal threads
Choosing 6h is appropriate when a balance between manufacturability and functional fit is required. It is often selected for general-purpose internal threads where moderate tolerance control is acceptable and where mating external threads will be made to a compatible external tolerance (for example, a common external tolerance position paired with 6h ensures reliable assembly). Professionals select this tolerance class when they require predictable fit, efficient production, and compliance with standardised thread specifications.
Key characteristics that distinguish 6h thread inspection
- Tolerance Grade: The numerical component prescribes the magnitude of acceptable deviation; grade 6 is commonly used for general engineering threads.
- Fundamental Deviation: The letter h establishes the deviation direction for internal threads, which for h means no positive allowance relative to the basic size.
- Functional Verification: The Go/No-Go Plug Gauge directly checks the component against the combined limits implied by 6h.
- Applicability: Suitable for serial production environments in mechanical engineering and machine construction where predictable fits are needed.

Metav’s emphasis on quality and certified production processes supports reliable, repeatable inspection results essential in high-volume manufacturing and precision engineering.
How to use a 6h Go/No-Go Plug Gauge correctly
To ensure valid results when inspecting an internal thread specified as 6h, follow standard best practices: clean the thread before inspection to remove chips and debris; apply gauges without forcing them—Go must enter smoothly and fully if the part is acceptable; and store gauges according to manufacturer guidance to preserve their calibration. Recording results and integrating gauge checks into the process control plan helps maintain traceability and prevents out-of-spec components from reaching assembly.
Summary and final recommendation
In short: "was ist 6h bei einem gewindelehrdorn?" — 6h is a thread tolerance designation that defines the allowable variation and fundamental deviation for internal threads; Go/No-Go Plug Gauges made to the 6h specification verify compliance quickly and reliably. Use norm-compliant gauges from reputable suppliers such as Metav IndustryLine to ensure precision, repeatability and seamless part interchangeability. The correct application of a Grenzlehrdorn tailored to 6h saves inspection time, reduces scrap and supports consistent product quality.
