JBO Thread Plug Gauge - Trapezoidal Go-No/Go - Right Hand - 7H - Tr. 8 x 1.5

The JBO Thread Plug Gauge is a go/no-go inspection tool designed to verify trapezoidal, right-hand threads in threaded holes. With a 7H tolerance class and an 8 x 1.5 thread size, it provides quick, reliable checks to confirm parts meet specification in production, automotive, and aerospace environments.

This gauge makes it easy to confirm proper fitment and identify non-conforming threads at a glance, helping reduce rework and speed up quality checks without sacrificing accuracy.

• Go-No-Go efficiency: Delivers a fast pass/fail result to speed up inspections and minimize downtime, so you can move parts through quality checks with confidence.
• Trapezoidal right-hand precision: Specifically designed to match trapezoidal threads, ensuring consistent measurements for the 8 x 1.5 size and 7H tolerance across components.
• Durable, knurled construction: Robust, slip-resistant grip and sturdy ends stand up to frequent use in busy shops, even with gloves or oily hands.

Used across production lines, maintenance workshops, and inspection labs, this plug gauge improves accuracy, reduces guesswork, and helps you consistently meet thread specifications with every check.
