Description

The JBO Thread Plug Gauge (NoGo) for Electrical Conduit is a compact, hand-held tool designed to quickly verify internal threads in conduit fittings and threaded holes. It's ideal for technicians, inspectors, and shop floor personnel across manufacturing, automotive, and aerospace environments.

With precise M75 x 1.5 right-hand threads, a 7H tolerance, and a robust knurled body, this gauge delivers reliable No-Go checks that help confirm correct fitment and reduce rework.

  • No-Go quick identification: The No-Go probe makes it fast to confirm non-conforming threads, helping you reject out-of-spec holes before assembly and avoid costly downtime.
  • Precise M75 x 1.5 right-hand threads with 7H tolerance: Ensures accurate measurement against standard conduit thread dimensions, improving first-pass acceptance and overall quality control.
  • Rugged, ergonomic knurled body: Provides a secure grip, durable performance in oily or busy shop environments, and long service life for daily use.

Using this gauge streamlines inspection workflows, speeds up assembly checks, and minimizes rework by confirming thread compatibility early. Its precise, reliable readings support consistent results across jobs, helping you meet quality standards without slowing down production.
