Limit plug gauge D21 mm H7 (TECWERK) — precision bore verification tool

Limit plug gauge D21 mm H7 for quick verification of bore diameters in production and quality inspection environments

• 21 mm nominal diameter
• H7 tolerance precision
• Compact inspection tool
• TECWERK brand quality

Keep production within specified tolerance limits

The H7 tolerance designation indicates a well-established fit class that ensures reproducible acceptance criteria for bore diameters. By checking a 21 mm bore with a limit plug gauge, operators obtain an immediate pass/fail verdict, reducing ambiguity in inspection routines. The measurable acceptance threshold provided by the tolerance helps to avoid downstream rework and supports consistent part interchangeability in assemblies.

Fast inline checks to increase throughput

A compact gauge of this type enables rapid spot checks at the machine, workbench or receiving inspection. The limit plug acts as a simple functional measure: insertion confirms conformity, rejection highlights out-of-spec conditions. This speeds up decision-making during batch runs and shortens inspection cycles, contributing to a more efficient production flow and fewer hold-ups on the shop floor.

Practical design for routine quality control

Designed for straightforward use in standard inspection processes, the plug gauge supports repeatable dimensional control without requiring complex setup. The tool’s clear nominal diameter and tolerance marking simplify documentation and record keeping during quality audits. Integration into existing inspection plans is uncomplicated, making it suitable for small series as well as volume production where daily checks are required.

From measurement to measurable savings

Using a dedicated limit gauge translates directly into lower scrap rates and less rework through early detection of out-of-tolerance bores. The simple, reliable measurement principle supports compliance with drawing specifications and engineering fits, helping to maintain product quality and customer satisfaction.
