Engineered for Accuracy, Built for Reliability

Each Go and No-Go Gauge is manufactured using precision grinding and lapping processes, ensuring extremely tight dimensional accuracy. This allows consistent inspection results even in high-volume production environments where repeatability and measurement integrity are critical for quality assurance.
The Go side confirms maximum material condition while the No-Go side checks minimum material condition. This simple yet effective logic eliminates human error and allows even semi-skilled operators to perform inspections confidently and accurately.
Precision ground and lapped surfaces reduce friction during inspection, preventing component damage and ensuring smooth gauge entry. This enhances user experience while maintaining consistent inspection pressure and minimizing wear on both gauge and workpiece.
Go and No-Go Gauge is manufactured according to IS, DIN, ISO, and ANSI standards, these gauges ensure universal acceptance across industries. This compliance guarantees compatibility with international quality systems and export-oriented manufacturing requirements.
Special heat treatment and anti-rust coating protect the gauges against corrosion and abrasion. This ensures stable performance even in harsh shop-floor conditions involving coolant exposure, humidity, or frequent handling.
Clear laser marking ensures permanent identification of gauge size, tolerance, and serial number. This improves traceability, simplifies calibration records, and prevents mix-ups during multi-product inspection processes.
Suitable for automotive, aerospace, engineering, hydraulics, fasteners, and heavy machinery industries, Go & No-Go Gauges adapt seamlessly to various manufacturing environments requiring dependable dimensional verification.

Product FAQ's

1. What are Go & No-Go Gauges used for?

Go & No-Go Gauges are used for fast and reliable dimensional inspection to determine whether a manufactured component falls within specified tolerance limits. They help manufacturers instantly accept or reject parts without complex measurement, making them ideal for high-volume production, in-process inspection, and final quality control applications.

2. How does a Go & No-Go Gauge work?

A Go & No-Go Gauge works on the principle of limit gauging. The “Go” side must enter or fit the component, confirming maximum material condition compliance, while the “No-Go” side must not enter, ensuring minimum material condition is not exceeded. This simple pass-fail method ensures quick, error-free inspection.

3. Do Go & No-Go Gauges require calibration?

Yes, periodic calibration is strongly recommended to maintain dimensional accuracy, reliability, and traceability. Calibration ensures the gauge remains within permissible tolerance limits and complies with quality management systems such as ISO, helping manufacturers maintain consistent inspection performance and audit readiness.

4. What standards do Go & No-Go Gauges follow?

At Dedicated Impex, Go & No-Go Gauges are manufactured strictly in accordance with recognized international standards such as IS, DIN, ISO, and ANSI. This compliance ensures global acceptance, accurate tolerance verification, seamless integration with certified quality systems, and suitability for export-oriented and multinational manufacturing supply chains.

5. What are the advantages of using Go & No-Go Gauges?

The main advantages of Go & No-Go Gauges include rapid inspection, reduced inspection cost, simple operation, minimal operator training, elimination of reading errors, and consistent quality control. They significantly improve inspection efficiency and productivity in high-volume manufacturing environments.

6. Can Go & No-Go Gauges be customized?

Yes, at Dedicated Impex, Go & No-Go Gauges can be fully customized to match specific customer and application requirements.
