A precision thread ring gage from Gage Assembly Company of Lincolnwood, Illinois, part number 1353AS120B, stamped with serial reference 00-366123 and internal code OD13. Manufactured in the USA, this is a GO-only special form ring gage configured for 1.497-2 ACME right-hand external threads, with a major diameter of 1.4970 in. The special form designation indicates that the thread geometry is not a standard general-purpose ACME 2G, 3G, or 4G profile but rather a custom form produced to a specific engineering requirement.

Gage Assembly Company has manufactured precision fixed-limit thread gages since 1953 using oil-hardened graphitic tool steel, lapped for accuracy and heat treated for long-term dimensional stability. The body shows the typical split-ring adjustable construction used in ACME thread ring gages for maintaining pitch diameter calibration.

A calibration tag is attached, showing ID number 00-366123, calibrated on 6-26-24, with a recalibration due date of 6-26-27. Calibration status should be independently verified upon receipt.

This gage is used to verify that an external ACME-RH threaded component will assemble correctly with its mating part by confirming that the thread form and pitch diameter fall within the GO tolerance boundary. Applications include lead screw inspection, actuator thread verification, and production quality control in machining and manufacturing environments where 1.497-2 ACME threads are specified.
