Functional bench gages provide a dedicated, repeatable way to verify machined features or relationships in a stable base-mounted fixture.

Functional verification
Check the way mating parts must work
A functional gage can confirm location, pattern, orientation, or fit using GO/NO-GO standards that are straightforward for the operator to understand.
- Hole pattern and feature location checks
- Mating-part or simulated-mating-part verification
- Orientation, phasing, and relationship checks
- Manual clamps, guides, and error-proofing
- Clear acceptance criteria for production use
Stable bench fixtures
Consistent loading and repeatable decisions
The fixture establishes how the part is located, supported, and checked. Arnold Gauge reviews datums, contact points, wear, operator access, and how masters or standards will be used.
Fixtures can be designed for a simple attribute decision or include variable indication and data collection when the application requires more detail.

Send the part, mating requirement, and acceptance criteria.
We will review the features, datum scheme, production environment, and operator needs.
