Description

VÖLKEL Precision Thread Rejection Gauge (NO GO) - M 48 x 2.0

The VÖLKEL Precision Thread Rejection Gauge is an indispensable testing tool in industrial manufacturing and quality assurance. As a NO GO gauge, it serves to check compliance with the upper tolerance limit of internal threads. Specifically manufactured for the size M 48 x 2.0 with tolerance class 6H, it ensures that your threads are not too large and meet the required standards.

What is a thread rejection gauge and how is it used?

A rejection gauge checks whether an internal thread exceeds the upper tolerance limit. The application is simple but precise:

The rejection gauge (NO GO) is screwed into the freshly cut thread by hand and without any special force.
It may be screwed into the thread for a maximum of two turns.
Should the rejection gauge be able to be screwed in for more than two turns, the thread is too large. It therefore does not meet the required standards and is considered rejected.

For a complete inspection, this rejection gauge is always used together with the corresponding GO gauge, which must be screwed into the thread completely. The matching GO gauge can be found under article number 16151.

Precision and Standards: What does tolerance 6H mean?

Tolerance class 6H is a standardized designation for metric ISO threads. It consists of two components:

The number "6" stands for the tolerance class, which determines the size of the tolerance field. In this case, it is a medium tolerance, which is suitable for most standard applications.
The capital letter "H" indicates the position of the tolerance field. "H" stands for a tolerance field whose lower deviation is zero, i.e., it is a basic profile. This thread has no play, which ensures a tight fit.

To ensure precise measurement results, a reference temperature of 20° Celsius is essential. At this temperature, all workpieces and gauges are standardized to avoid measurement errors.

Factory Calibration Certificate for Maximum Safety

As a manufacturer, VÖLKEL offers you the option of purchasing a factory calibration certificate upon request. This is available for an additional charge. The calibration is carried out in a measuring laboratory independent of VÖLKEL's production to ensure maximum objectivity. The inspection is performed according to the relevant standards (DIN, ISO, ANSI) and is carried out on state-of-the-art IAC thread scanners. This gives you measurable and documented assurance of the precision of your gauge.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between a GO and a NO GO gauge? The GO gauge (article no. 16151) checks the lower tolerance limit and must screw in completely. The NO GO gauge (rejection gauge, article no. 16173) checks the upper tolerance limit and may be screwed in for a maximum of two turns.
Q2: What does tolerance class 6H mean? The number "6" stands for the tolerance class of the thread. The letter "H" means that the lower deviation is zero. This ensures that the thread has no oversize and is a tight fit.
Q3: Why is the reference temperature of 20° Celsius important? Metals expand with heat. To ensure that measurement results are always comparable and compliant with standards regardless of the ambient temperature, a standard temperature of 20° Celsius has been set at which measurements should be performed.
Q4: How often should I have my thread gauge calibrated? The frequency depends on the usage. For industrial applications, a calibration cycle of 1-2 years is often recommended to ensure accuracy. More frequent calibration may be useful with intensive use.
Q5: Can I also use the rejection gauge for other thread sizes? No. Each thread gauge is a precision tool manufactured exactly for a specific thread size (here: M 48 x 2.0) and a specific tolerance class (6H). Using it for other sizes would lead to incorrect inspection results.

With the VÖLKEL Precision Thread Rejection Gauge, you ensure that only workpieces that meet the highest quality standards are put into circulation. A must for any professional quality management.
