Gauge Fixtures

A gauge fixture (also known as a checking fixture or inspection fixture) is a custom-made tool used after a product is made to check if it meets the required quality and size specifications. It is a quality control device.
Here is the simple breakdown of what it does:
• Checks Quality: Its main job is quality control—it verifies if the manufactured part is within acceptable limits (tolerances) or if it should be rejected.
• Holds the Part Still: It securely holds the finished product in a specific position for inspection, making it easy to check complex shapes that are hard to measure with standard rulers or calipers.
• Acts as a Template: The fixture itself often has specific surfaces or holes built in. An inspector uses measuring tools (like a feeler gauge) to check for gaps between the fixture and the part to confirm the dimensions are correct.
• Ensures Consistency: By using the same fixture every time, manufacturers ensure that every single part is measured exactly the same way, preventing human error in quality checks.
In short, a gauge fixture is a dedicated inspection tool that uses a custom-made template to confirm if a finished part is perfectly shaped and sized before it goes to a customer.
