Grenzlehrdorn DIN 7150-2/7164, H7

A limit plug gauge in accordance with DIN 7150-2 and 7164 with tolerance class H7 is a precise testing tool for checking the dimensional accuracy of bores and internal fits. These limit plug gauges are essential in quality assurance and production to ensure that the manufactured bores meet the given specifications and tolerances.

Main features:

1. Standardization:

   • DIN 7150-2 and 7164: These German industry standards define the requirements and specifications for limit plug gauges used for testing bores and internal fits.
   • H7 tolerance class: H7 is one of the most common tolerance classes for bores and defines a tight fit that ensures high dimensional accuracy.

2. Function:

   • GUT side (GO): This side of the limit plug gauge checks whether the bore has at least the specified minimum dimension. The GO side must be able to be inserted into the hole without great resistance.
   • OUTSIDE (NO-GO): This side of the limit plug gauge checks that the hole is not larger than the maximum permissible dimension. It must not be possible to insert the NO-GO side into the hole.

3. Material and construction:

   • High quality materials: Manufactured from hardened steel for high wear resistance and durability.
   • Precise manufacturing: Manufactured with high accuracy to ensure reliable and repeatable test results.

Applications:

• Quality assurance: Checking the dimensional accuracy of bores in production to ensure that manufactured parts meet specifications.
• Production: Regular inspection of bores to ensure compliance with tolerances and minimize rejects.
• Precision mechanics and mechanical engineering: Used in areas that require high precision and reliability in bore testing.

Advantages:

• High accuracy: Precise inspection of bores to ensure they meet the required specifications and tolerances.
• Reliability: Guarantees the dimensional accuracy and functionality of the manufactured bores.
• Easy handling: Quick and uncomplicated inspection of holes by simply inserting the plug gauge.
• Conformity to standards: Compliance with international norms and standards, which ensures a high level of acceptance and usability in various branches of industry.

Summary:

A limit plug gauge in accordance with DIN 7150-2 and 7164 with tolerance class H7 is an indispensable testing tool in mechanical production and quality assurance. It provides a precise and reliable method for checking the dimensional accuracy of bores and makes a significant contribution to ensuring the quality and accuracy of fit of the manufactured parts. Thanks to its standard-compliant design and high accuracy, it is indispensable in many technical and industrial applications.
