The EMUGE L0100100.5613 is a double-end STI plug thread gage designed to verify internal STI (Screw Thread Insert) threads to ASME B1.2 standards. One end checks the Go condition; the other checks the No Go condition, allowing a technician to confirm both the minimum and maximum thread tolerance in a single tool. Manufactured from tool steel with a bright, uncoated finish, it is built for repeated use in production and inspection environments. A short-form certification is included, supporting basic quality documentation requirements. A handle is included with the gage.
This gage is used to inspect 6-32 Class 2B right-hand STI threaded holes - the type of thread found when a Heli-Coil or similar wire thread insert has been installed in a parent material. Typical applications include aerospace, automotive, and general manufacturing inspection where repaired or reinforced threaded holes must meet tolerance before assembly. Machinists, quality inspectors, and toolroom technicians are the primary users of this gage in both shop-floor and inspection-bench settings.
Designed to inspect 6-32 Class 2B right-hand STI threaded holes produced with screw thread inserts per ASME B1.2 requirements.
Thread gages are inspection tools, not cutting tools - never force the Go end into a hole or apply torque beyond hand pressure. Clean the threaded hole before gaging to remove chips, coolant, or debris that could produce a false reading. Store the gage in its case when not in use to protect the thread form from damage. Periodic recalibration against traceable standards is recommended to maintain measurement integrity over time.
