VCOIL Plug Gauge (NoGo) - Metric (STI) - Heli Coil Gauge - Right Hand - 4H - M52 x 3

The VCOIL NoGo Plug Gauge is a metric, STI-compliant thread gauge designed for Helicoil inserts. This right-hand gauge combines go/no-go verification in a single tool to precisely check M52 x 3 threads, making it a reliable choice for technicians and quality inspectors.

• Combination Go/No-Go design: A single thread limit plug gauge that provides both go and no-go checks for efficient, one-tool verification.
• ANSI/ASME STI standards compliance: Manufactured and assessed in accordance with the relevant American National Standards Institute / ASME thread system.
• Red scrap-ring marking: The scrap side is clearly marked with a red ring for quick identification during inspections.
• Go end usability: The go end must screw into the thread cut into a part by hand without using excessive force.
• No-Go limit: The scrap end must not be able to be manually turned more than two turns into the cut thread.
• Right-hand orientation: Specifically configured as a right-hand gauge for compatible assemblies.
• Metric thread size: M52 x 3 with 4H tolerance class.
• Reference temperature: Measurement reference is 20°C for parts and gauges.
• Construction and grip: Durable metal body with knurled grip for secure handling during use.

This gauge helps QC teams quickly confirm both fit and interference thresholds for Helicoil inserts, reducing rework by catching out-of-tolerance threads at the source. By using a consistent 20°C reference and a clearly marked scrap side, operators achieve repeatable, standardized results across shifts and machines for M52 x 3 threads.
