Inspection Fixtures & Relation Gauges — Checking Fixtures

About the Inspection Fixtures Relation Gauges

A relation gauge verifies the relationship between features — hole to hole, profile to datum, flange to face — rather than a single isolated dimension. On a formed or fabricated part that is the only way to get a repeatable answer, because hand instruments measure from wherever the operator holds them.

Key Features

Built to the component drawing datum scheme, not to convenient features
Attribute (go/no-go) or variable (measured) read-out as required
Locators and supports representing the drawing datums exactly
CMM verification and gauge R&R study available at handover
Identified for entry into your calibration schedule with a recall interval

Ideal For / Applications

Automotive component inspection under PPAP
Formed sheet metal and fabricated assemblies
Machined component verification
Incoming inspection of bought-out parts
Production sorting where a CMM would be too slow

Frequently Asked Questions

What is a relation gauge?

An inspection fixture that verifies the relationship between two or more features — hole-to-hole spacing, profile against a datum face, flange orientation — instead of a single isolated dimension.

Attribute or variable gauge — which do I need?

An attribute gauge gives pass or fail: fast, needs no skill, but gives no warning of drift. A variable gauge gives a measured deviation that can be plotted on a control chart. SPC requirements demand a variable gauge.

Do you supply certification?

Yes, on request — CMM verification against the drawing datum scheme plus a gauge repeatability and reproducibility study, which is normally what a PPAP submission requires.
