The JBO Thread Ring Gauge (GO) for UNEF, Right Hand, 2A, 1 1/8 x 18, is a precision tool designed to verify external thread diameters quickly and reliably. It’s ideal for machinists, inspectors, and quality teams across manufacturing, automotive, and aerospace applications who need to confirm that threaded components meet UNEF 2A GO requirements.

Built from hardened steel, this gauge delivers durability that stands up to demanding shop floor use while preserving dimensional accuracy. Its Go-side design makes it easy to identify conforming parts at a glance, helping to speed up quality checks and keep production moving.

• Fast Go/No-Go Verification: Quickly confirms whether external UNEF 2A threads at 1 1/8 x 18 meet the GO limit, reducing inspection time and rework.
• Durable Hardened Steel Construction: Built to withstand daily shop use and wear, maintaining accurate dimensions over many cycles for long tool life.
• Precise UNEF GO Geometry: Manufactured to exact UNEF GO specifications, delivering repeatable, reliable readings that align with other gauges in your metrology toolkit.

By incorporating the JBO Thread Ring Gauge into your inspection routine, you gain faster, more consistent checks, reduce guesswork, and improve first-pass acceptance of threaded components. This reliable, purpose-built gauge supports strict standard compliance and helps you maintain high quality across every batch.
