Limit plug gauge 19 mm H7 (TECWERK)

Limit plug gauge 19 mm H7 (TECWERK) is a precision inspection tool for quick pass/fail verification of holes manufactured to a 19 mm nominal diameter with an H7 tolerance, suitable for production and incoming inspection.

• Limiting plug gauge, nominal Ø 19 mm H7
• Precision tolerance H7 for reliable inspection
• Supplied as single unit

Fast, reliable verification for hole tolerances

The limit plug gauge provides an immediate pass/fail check for holes specified as 19 mm nominal with H7 tolerance. H7 is a standard ISO tolerance grade that defines the permissible dimensional deviation for the hole; the gauge is sized to represent the upper/lower limit so that a simple insertion test indicates compliance. This approach reduces interpretation time compared with detailed measuring devices while maintaining objective verification criteria for routine quality control.

Increase inspection throughput and reduce uncertainty

Using a dedicated go/no-go gauge accelerates quality checks and supports consistent decision-making in assembly and machining workflows. By replacing repeat micrometric checks for every part, the plug gauge helps increase inspection throughput and reduces handling time, allowing operators to focus on critical production steps. The simple tactile result — either the gauge passes or it does not — minimises subjective judgement and contributes to measurable reductions in scrap and rework.

Straightforward workshop use and integration

The compact design and single-unit supply make the gauge easy to store and integrate into existing inspection routines. The tool is intended for quick, repeatable verification of drilled, reamed or bored holes to the H7 specification and is suitable for use at incoming inspection, in-process checks and final inspection stations. When additional technical data are required or application-specific advice is needed, specialists are available to discuss fit-for-purpose use and traceability considerations.

FAQ

What does H7 mean for a 19 mm hole?
H7 denotes an ISO hole tolerance grade; for the TECWERK limit plug gauge the H7 marking defines the permissible deviation range around the 19 mm nominal size that the gauge checks.

How is the gauge used in production checks?
The limit plug gauge is used as a go/no-go check: if the gauge inserts cleanly, the hole meets the H7 requirement; if it does not insert, the part fails the inspection.

Is the TECWERK limit plug gauge suitable for incoming inspection?
Yes, the TECWERK limit plug gauge with nominal 19 mm H7 is designed for incoming part verification as well as in-process and final inspection tasks.

How often should the gauge be verified?
Periodic verification is recommended in line with quality procedures; the gauge should be checked at defined intervals to ensure continued conformity to the nominal 19 mm H7 specification.
