The JBO Thread Ring Gauge (NoGo) — Metric Fine — Right Hand — 4h — M25 x 1 is a precision inspection tool built for engineers, machinists, quality teams, and production professionals who work with external threads. Designed for metric fine threading, this gauge provides a reliable max-diameter check to verify that parts meet the M25 x 1 right-hand thread specification without guesswork.

Crafted from hardened steel, the gauge delivers durable performance in busy shops and demanding environments. The NoGo design yields an immediate pass/fail readout during inspection, helping you speed up quality checks and maintain consistent results across batches.

• Metric fine M25 x 1 NoGo configuration: Precisely matched to the M25 x 1 right-hand thread, delivering a clear maximum-diameter limit so inspectors can confirm parts meet spec quickly and consistently.
• Hardened steel construction: Built to endure daily use, resisting wear and maintaining accurate dimensions over many inspections for long tool life.
• Clear Go/NoGo indication for quick decisions: Simple, unambiguous results that reduce guesswork, cut inspection time, and help prevent non-conforming parts from moving downstream.

Using this gauge helps streamline threading inspections, improve first-pass yields, and support reliable assembly and performance in your processes. It supports faster QA, lower scrap, and more predictable manufacturing outcomes across the board.
