Choosing a fixture for dimensional metrology machine inspection often comes down to one question: will the part stay exactly where you put it while the probe does its work? A clamp that allows even a little movement can force a rerun. For shops that want a simple, repeatable hold-down, the DANTECH CMM Tension Clamp L87mm offers a compact solution - but it's not a universal tool.
Quick verdict
At $26.00, this CMM tension clamp gives you a single holding point with an M6 thread. The set contains one 87 mm tension clamp and one 78 mm post. If you need a fixed, no-adjustment holding setup, this is an easy pick.
Who it suits
It suits inspection routines where parts fit within a compact footprint and don't need to be repositioned mid-check. The fixed-board, fixed-pole design makes it a fit for operators who want dependable clamping without a lot of moving parts. This is practical in dimensional metrology machine inspection environments where repeatability matters more than flexibility.
What stands out
#### DANTECH CMM Tension Clamp L87mm
The headline feature is the 87 mm clamp length paired with a 78 mm post and an M6 thread. The 'Spring Fixed Board Fixed Pole' wording points to a clamp that maintains tension in a fixed position, rather than offering angles or articulation. The set includes one tension clamp and one post, so it's ready to use as a single inspection point.
The strongest reason to choose it is the simple, focused design: one clamp, one post, and the M6 thread all come together in a single package. The flip side is the fixed geometry. With a fixed board and fixed pole, you won't get angle adjustment from this clamp. If you need to hold a contoured or irregularly shaped part, you may need more than one unit.
Meaningful trade-offs
The main trade-off is flexibility. A fixed clamp can't be angled, tilted, or repositioned to follow a curved surface. That's fine for flat or regular parts, but for a one-off complex shape, you'll likely need supplementary tooling or additional clamps. The fixed design also means you'll plan for multiple units if your part needs more than one holding point.
Bottom line
The DANTECH CMM Tension Clamp L87mm is a straightforward solution for a specific job. It doesn't promise adjustability or versatility; it promises a secure holding point for consistent, accurate inspection. If that's what your dimensional metrology machine inspection setup needs, the $26 price makes it an easy addition.
