The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 4h, M38 x 1.5 is a precision inspection tool designed to verify external thread sizes on machined parts. It helps quality teams, engineers, and workshop staff quickly confirm whether a component meets the M38 x 1.5, 4h metric fine-thread standard, ensuring consistent fit and function.

• Fast NoGo checks for M38 x 1.5: Quickly determine whether a part’s external thread falls inside tolerance, speeding up quality control and reducing inspection downtime.
• Hardened steel construction: Built to withstand the rigors of busy shops, offering excellent wear resistance and enduring accuracy through many measurement cycles.
• Precise, repeatable metric fine-tap alignment: Designed for right-hand threads with 4h tolerance, providing reliable pass/fail results that support consistent manufacturing quality.

Using this gauge simplifies decision-making in production and QA processes. It helps you minimize rework, streamline inspections, and maintain tight dimensional control across batches, so you can trust every threaded component to perform as intended.
