Thread Gauges for Accurate & Reliable Inspection

We supply high-quality thread gauges designed for precise inspection of internal and external threads across a wide range of industries. Whether you are working in precision engineering, manufacturing, automotive, oil & gas, or general production, our thread gauges ensure consistent quality control and compliance with industry standards.

Plug Gauges

Our thread plug gauges are manufactured for checking internal threads with accuracy and repeatability. Available in:

  • Plug Gauge (D/E)
  • Plug Gauge (GO)
  • Plug Gauge (Go/NoGo)
  • Plug Gauge (NoGo)

GO gauges check the maximum material condition, while NO GO gauges verify minimum tolerance limits — helping Engineers maintain tight quality control and reduce costly rework.

Ring Gauges

Our thread ring gauges are ideal for inspecting external threads and are available in:

  • Ring Gauge (GO)
  • Ring Gauge (Go/NoGo)
  • Ring Gauge (NoGo)

Manufactured to strict tolerances, our ring gauges provide reliable measurement for production environments where accuracy is critical.
