Hold It Steady, Measure It Right: Shop CMM Fixtures at Penn Tool Co.
A coordinate measuring machine is only as accurate as the part sitting on its table. If a workpiece shifts, rocks, or isn't referenced consistently between runs, even the most capable CMM will return numbers that don't hold up. Reliable CMM fixtures solve that problem at the source, locking parts in place so every probe touch measures the part, not the setup.
Since 1968, Penn Tool Co. has supplied machine shops, inspection departments, and quality labs across the USA with the workholding and measurement equipment that keeps inspection results repeatable. Our selection of CMM fixturing gives your team dependable ways to locate, clamp, and reference parts for consistent, trustworthy CMM results.
Build a Better Inspection Setup With Flexible CMM Fixturing Solutions
Different parts and programs call for different fixturing approaches. A CMM fixture kit bundles the modular components, plates, clamps, and locating elements needed to build custom setups without sourcing each piece separately, giving inspection teams a flexible starting point for varied part geometries.
For securing parts once they're positioned, CMM fixture clamps hold workpieces firmly against the fixture base without introducing distortion that would throw off a measurement. Broader CMM workholding solutions extend beyond individual clamps to complete systems, ranging from simple locating pins to full custom fixture plates built around specific part families.
A dedicated CMM inspection fixture is often built or configured for a single part number, repeatable run after run on a production line where the same component gets measured shift after shift. For shops handling a wider mix of parts, modular CMM fixturing offers reconfigurable grid plates and interchangeable components that adapt to new geometries without a full fixture rebuild.
For a flexible staging surface, TE-CO Aluminum Fixture Plates provide an alpha-numeric grid pattern for building CMM fixture setups, while TE-CO Fixturing Towers provide a vertical fixturing solution for longer or flat parts that need to be inspected from multiple sides.

Smarter CMM Fixturing Trends Transforming Modern Inspection
As American manufacturers push toward faster changeovers and more flexible inspection cells, CMM fixturing design continues to evolve.
- Modular Grid Systems: Shops are moving away from single-purpose fixtures toward reconfigurable grid plates that adapt to multiple part families.
- Zero-Point Clamping: Quick-change zero-point systems are cutting setup time between parts, letting inspectors swap fixtures without re-referencing the machine.
- Low-Distortion Clamping Materials: Fixture components are increasingly engineered to minimize the clamping force distortion that can skew fine-tolerance readings.
- Automated Fixture Compatibility: As CMM programs integrate with automated part loading, fixtures are being designed for consistent robotic placement and repeatable part presentation.
- Custom Fixture Design Services: More facilities are turning to application-specific fixture design rather than adapting generic components, particularly for complex or high-value parts.
Precision Workholding Built for Consistent, Repeatable CMM Inspection
A part that shifts mid-measurement rarely announces itself; it shows up later as a dimension that doesn't match the CAD model or a batch of parts that fails final inspection for reasons no one can trace. Dependable CMM fixture clamps and workholding components catch that variance before it reaches your quality report.
50+ years of precision instrumentation experience shapes how we stock this category and every other one in our gaging lineup, helping your inspection team hold parts steady and measure with confidence, setup after setup.
