The "SPO Series 2→1" is a one-way screw gauge that allows for measurement in one action, improving work efficiency compared to the traditional two measurements using a plug gauge for through and stop. The through-side screw plug gauge can be inserted without difficulty, and if it stops at the stopper end face, it can be judged as passing. Since the through side acts as a guide, it prevents misjudgment on the stop side. 【Features】 ■ The handle is equipped with a ratchet mechanism to prevent over-tightening. ■ Made from gauge steel (SKS3, HRC58 or higher), it has excellent wear resistance. ■ To ensure customer trust and peace of mind, a inspection report is included. *For more details, please download the PDF or feel free to contact us.

The "SPW Series" is a carbide screw plug gauge for metric threads that uses carbide only for the frequently used through-side gauge. The blind-side gauge achieves wear resistance and low cost by using conventional SKS3 equivalent steel. 【Features】 ■ Offers 5 to 10 times the lifespan compared to steel plug gauges - Varies depending on the material of the measured object - Can accommodate screw gauges other than standard stock items ■ "Carbide Screw Ring Gauge for Metric Threads" is also available *For more details, please download the PDF or feel free to contact us.

The "EMC Series" is a pin gauge set that allows for the calibration of the micrometer's instrument tolerance, the feed error of the spindle screw, and the parallelism and flatness of the spindle and anvil at every 1/4 rotation. It can be used for in-house calibration of micrometers and calipers to obtain and maintain ISO 9000 series certification. [Usage Examples] ■ Measurement of the micrometer's instrument tolerance and the feed error of the spindle screw ■ Verification of the parallelism and flatness of the anvil and spindle at every 1/4 rotation *For more details, please download the PDF or feel free to contact us.

The "SPS Series Pos-T" is a screw position gauge that can measure the position of screw holes with high precision. The screw section conforms to the standards of through-type screw plug gauges, allowing for simultaneous checking of the screw hole's pass. Additionally, it comes with a detachable knurled handle to prevent direct contact with the gauge section (please remove it if it interferes with measurement). 【Features】 ■ The perpendicularity can be confirmed by observing the gap at the end face of the pin gauge section. ■ The gauge material is gauge steel (SKS3, HRC58 or higher), which offers excellent wear resistance. ■ To ensure customer trust and peace of mind, an inspection report for the screw gauge section and pin gauge section is included. *For more details, please download the PDF or feel free to contact us.
