Product Info

Gauges are indispensable tools in industrial quality control, helping ensure dimensional accuracy of holes, edges, and surfaces. This article outlines common types of gauges and how to select the right one based on your application—whether in mass production or high-precision lab settings.

A gauge is a critical instrument in measurement and quality control, used to verify dimensions and ensure the accuracy of workpieces based on engineering standards. From inspecting small holes to flatness and outer dimensions, gauges enable efficient, reliable results without requiring complex data interpretation—perfect for streamlined production workflows.

In precision-driven industries such as automotive, electronics, and mold manufacturing, selecting the correct type of gauge is essential to maintain accuracy, reduce errors, and ensure compliance with specifications.

Common Types of Gauges and Their Key Features
● Pin Gauge
Best for checking small holes (pin, punch, drilled types). Go/No-Go functionality makes inspections simple. High-quality models offer minimal tolerance and polished finishes to prevent part abrasion.
● Plug Gauge
Used for medium to large hole inspection, with “Go” and “No-Go” ends to verify dimensional compliance. Excellent for high-volume production requiring quick and reliable decisions.
● Gauge Block
Precision calibration tools, ideal as length standards for other gauges. Offer accuracy up to ±0.0001 mm. Crucial for calibration and QA laboratories.
● Dial Gauge
Checks flatness, concentricity, and height variations using an analog dial. Typically mounted on fixtures for consistent, precise readings.
● Snap Gauge
Used to measure external dimensions of shafts and cylindrical parts. Simple and fast operation, suitable for mass production lines.
