VCOIL Plug Gauge (NoGo) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M45 x 4.5

Precision metric Go/No-Go thread plug gauge for right-hand M45 x 4.5 threads, designed for Helicoil gauge applications and strict ANSI/ASME thread verification.

• Go/No-Go design: Combined thread limit plug gauge with go and no-go ends to verify both acceptance and rejection criteria.
• Thread size: Metric M45 x 4.5.
• Thread class: 4H.
• handedness: Right Hand configuration.
• Standards: Manufactured and assessed to ANSI/ASME thread system requirements.
• Scrap indicator: Red ring marks the scrap side for quick visual identification.
• Go end test: Must screw into the thread cut in a part by hand without applying excessive force.
• No-Go test: Must not be turned more than two full turns into the cut thread when tested.
• Reference temperature: Parts and gauges are referenced at 20°C for measurement consistency.
• Application: Designed for Helicoil gauge checks, ensuring reliable thread verification in manufacturing and assembly environments.

Using this gauge helps ensure consistent thread quality across production runs by clearly validating proper fit (Go) and limiting oversize or undersize conditions (No-Go). The red scrap indicator simplifies on-the-floor inspections, while the hand-tight Go test reduces the risk of thread damage during verification. Built to align with recognized ANSI/ASME standards and the STI metric specification, it supports precise, repeatable checks for M45 x 4.5 right-hand threads in helicoil-related workflows.
