SPS Series

Thread Position Alignment Gauge Pos-T

Explanation about series

The thread section serves as the GO side thread plug gauge, allowing for very precise measurement of the hole position.

SPS Series
 

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!
