SPS Series
Thread Position Alignment Gauge Pos-T
The thread section serves as the GO side thread plug gauge, allowing for very precise measurement of the hole position.
Dimensions
Features
- The thread section satisfies GO side thread plug gauge standards, so that can do GO check of a tapped hole at the same time.
- Checking the squareness is possible by checking the gap with the end face of pin gauge section.
- The gauge material is Gauge steel (SKS3, HRC58 or harder), and the gauge has exceptional wear resintance.
- This gause is equipped with a removable knurled handle, not to touch the pin gauge section directly (The handle can be removed if it interferes with the measurement).
- An inspection report for the thread gauge and pin gauge sections is included with to provide confidence and assurance for users!
Example
- Measurement with three coordinate measuring machine
- Measurement with a height gauge
- Center-to-center measurement with calipers
Accuracy
- The thread centrality (afferent) acts by fastening, and the thread positioning alignment gauge can maintain the tapped hole center.
- ⇒Repeatability error of less than 10μ (based on in-house test)
- Supporting with the end face of pin gauge section, so that it almost never falls over!
