What your quality team actually checks
What your quality team actually checks
Positioning is where results scatter
A hardness reading is only valid if the part is held rigidly at the specified point. A fixture designed to your geometry removes part movement and operator placement as sources of scatter — so the reading reflects the material, not how the piece happened to sit.
A hardness-testing engineer on the line
Send your part and the tester it runs on; QATM engineers the fixture to locate and clamp it precisely. We supply the whole hardness-testing chain, not just parts. Sub-4h reply, NDA standard.

About this product
QATM clamping fixtures hold a workpiece securely and repeatably in a hardness tester so the indentation lands exactly where the specification requires — custom-designed to your part geometry for round, tubular, irregular and small components.
Why the fixture matters as much as the tester
A hardness reading is only valid if the part is held rigidly at the right position — the fixture is what makes the result repeatable.
Secure, repeatable positioning
The part is clamped rigidly so it can’t shift under test load, and it seats the same way every time — the indentation lands at the specified point on every piece.
Designed to your part
Each fixture is engineered to the specific geometry — round bars, rings, tubes, gears or irregular castings — so awkward shapes are located precisely instead of balanced by hand.
Standard-compliant results
Stable clamping removes part movement as a source of scatter, so Vickers, Brinell and Rockwell readings stay within the tolerance your standard requires.
Fits your QATM tester
Fixtures are matched to QATM and QNESS bench hardness testers and to automated testing plants, so they integrate with the equipment you already run.
How Additive Plus supplies your fixtures
A fixture is engineered around your part and your tester — send us both and we build it.
Step 01
Send part and tester
Share the workpiece geometry (or a drawing) and the hardness tester or plant it runs on, plus the required test positions.
Step 02
Designed and built in Austria
QATM engineers the fixture to locate and clamp your part precisely, and manufactures it to fit your tester.
Step 03
Fit and verify
The fixture is fitted and checked so the indentation reaches the specified point repeatably before it goes into production use.
Repeatable positioning, part after part
Odd geometries — round bars, rings, tubes, gears and irregular castings — are the parts most likely to move under a hardness indenter or to be positioned differently by each operator. A custom clamping fixture locates and holds them the same way every time, so the test point is exactly where the drawing specifies and the reading reflects the material, not how the part happened to sit. Fixtures are matched to QATM and QNESS bench testers and to automated hardness testing plants.

Common questions

What do clamping fixtures do in hardness testing?
A clamping fixture holds the workpiece rigidly in the hardness tester so it cannot shift under the test load and always seats in the same position. That matters because a hardness reading is only valid if the part is stable and the indentation lands at the specified point. The fixture removes part movement and operator placement as sources of result scatter.
Are the fixtures custom-made to my part?
Yes. Each clamping fixture is engineered to the specific geometry of your workpiece — round bars, rings, tubes, gears, shafts, irregular castings or small components — and to the hardness tester it runs on. You send the part or a drawing plus the tester model and required test positions, and QATM designs and builds the fixture to suit.
Which hardness testers are the fixtures compatible with?
The fixtures are matched to QATM and QNESS bench hardness testers — such as the QNESS 10/60 micro-macro range and the QNESS 250/750/3000 universal testers — and to automated hardness testing plants. Because they are made by the manufacturer of the testers, they fit without adapting or shimming.
Which workpiece shapes can they hold?
Clamping fixtures are most useful for parts that will not sit flat and stable on a standard anvil: round bars and rings, tubes and pipes, gears and shafts, irregular castings and small components. The fixture locates the curved or asymmetric surface precisely and holds it under load, so the test point is exactly where the drawing specifies on every piece.
What is the lead time and how do I order?
Clamping fixtures are made to order with a typical lead time of 3–6 weeks depending on complexity. To order, send your workpiece geometry or drawing, the hardness tester or plant it runs on, and the required test positions — Additive Plus returns a fixture proposal and quote. Fixtures can also be ordered together with a QATM or QNESS tester and matched as one system.
