Precision Plain Plug Gauge GO and NOGO Set for Hole Size Inspection
Smooth plug gauges can be customized in various specifications according to user needs. These precision measuring tools serve as dimensional benchmarks and comparative measurements. The structure is simple, typically consisting of solid forms with accurate size and shape, such as cylinders or cones.
When ordering, please specify requirements (example: 8 plug gauge 6H GO and NOGO).
Deko Corp provides a complete line of smooth plug gauges available in sizes from 1.8 to 300. These tools are used to measure the inner hole size of workpieces. Each set includes both maximum limit size (NOGO end) and minimum limit size (GO end) components.
- Smooth plug gauge design for precise measurements.
- Available in multiple accuracy grades: H6, H7, H8.
- GO, NO GO, and combination GO/NOGO types available.
- Conforms to DIN7162 standard.
- Wear-resistant and corrosion-resistant construction.
- Stable structure for reliable performance.
- Supplied in protective fitted case.

- Hole inspection: Primary use for inspecting workpiece hole sizes to ensure compliance with design specifications.
- Quality control: Essential tool in production quality control to verify dimensional accuracy.
- Standardized production: Ensures consistency across production batches, improving efficiency and product quality.
- Inspect gauge surfaces for cleanliness and defects before use - ensure markings are clearly visible.
- Use only during valid calibration period with proper certification.
- Maintain measurement environment at approximately 20°C.
- Apply minimal force - avoid pushing, rotating, or tilting the gauge.
- Insert/remove gauge along hole axis only.
- Clean thoroughly after each use to maintain accuracy.
