In dimensional metrology machine inspection, the part under measurement needs to stay exactly where you put it. A small shift during a probing cycle can turn a good setup into a false reading. A tension clamp gives you a simple way to lock a workpiece to a fixture plate, and the CMM Fixtures Tension clamp R-CT-160-275-20 from SUXING is built around that purpose.

Quick verdict

The R-CT-160-275-20 is a straightforward fixture clamp for inspection work. It comes as a set with one tension clamp and one post. The clamp is 55 mm long, the post is 78 mm long, and the thread is 1/4-20. The price is USD 20.21. For a basic hold-down point, this set gives you the main pieces in one package.

Who it suits

This clamp suits anyone working with dimensional metrology machine inspection who needs a compact, threaded clamping point on a fixture. It is especially useful for smaller parts that need a steady hold while a CMM takes readings. Because the set includes both the clamp and the post, you can add a clamping point without hunting for extra fixture hardware.

What stands out

The two key dimensions make a difference. A 55 mm long clamp is short enough for tight fixture spaces, while the 78 mm post lifts the hold point higher. The 1/4-20 thread defines the connection size you will be working with.

Meaningful trade-offs

The main trade-off is the set's packaging: it covers one clamping point. If your fixture needs several, plan for multiple sets. The fixed geometry works well for compact parts; a larger workpiece may require a different clamping setup.

Bottom line

The SUXING CMM Fixtures Tension clamp R-CT-160-275-20 is a practical choice when you need a new hold-down point for CMM inspection. With clear dimensions and a USD 20.21 price, it gives you a defined starting point. Plan for one set per clamping point.

Product note

CMM Fixtures Tension Clamp R-CT-160-275-20

This tension clamp set from SUXING covers the essentials for a single clamping point, including the post and clamp. The thread size is part of the connection design. On the downside, the set includes one clamp and one post, so a fixture with several hold-down spots will require additional sets.
