OSG’s October 15 announcement lists the EYE-TC internal-thread pitch-diameter measuring system as launching that day, with 38 items spanning its stated M8×1.25 to M30×1.5 range. This published launch notice does not confirm present stock, a quotation or international supply.
A number is not the same as a pass/fail decision
The product page describes comparison measurement using a calibration master ring and digital display of pitch diameter. It separately states that internal-thread acceptance is assessed with thread limit gauges. EYE-TC should therefore not be presented here as replacing the limit-gauge decision. We have not independently examined the cited JIS requirements or verified measurement accuracy.
OSG lists a three-point measuring head, a master ring and a display unit. It also states compatibility with an existing Mitutoyo ABS Borematic display; a complete purchasing configuration still requires confirmation.
Gauge-making history
OSG’s history records the start of thread-gauge manufacturing in May 1942. This background explains a longstanding product area without turning company history into a calibration certificate for EYE-TC.
