Asimeto Plug Thread Gauges (Go/NoGo) in Imperial sizes are precision tools for quality-control professionals who verify internal thread accuracy. This right-hand gauge is sized for 3/8 x 18 threads and aligns with ASMEB1.20.1-2013 standards, delivering reliable go/no-go results during inspection and assembly.

• Go/NoGo design: Separate go and no-go elements provide quick, decisive checks of thread depth and tolerance.
• Imperial size: 3/8 x 18 threads, right-hand orientation standard for common internal threads.
• Right-hand threading: Matches the most frequently used internal thread direction in machining and manufacturing.
• 3-step L3 design: Three distinct depth checks ensure comprehensive assessment of thread engagement and clearance.
• Standards compliant: Precisely aligned with ASMEB1.20.1-2013 internal thread specifications for reliable QC.
• Durable, production-ready construction: Built for repeated use in busy workshop environments while maintaining measurement integrity.

This gauge accelerates quality control by providing clear go/no-go results that help you catch undersized or oversized threads before parts move to the next stage. It’s ideal for machining shops, assembly lines, and quality labs where consistent, traceable internal-thread verification is essential. Use it to validate 3/8 x 18 threaded cavities, prevent misfits, and support efficient, repeatable inspections across shifts.
