JBO Thread Plug Gauge - UNF Go-No/Go - Left Hand - 2B - No. 0 x 80 is a precision inspection tool designed to verify UNF threaded holes quickly and reliably. Tailored for engineers, shop floor technicians, and quality inspectors, it helps ensure threads meet specified standards during manufacturing, automotive, and aerospace tasks. With a compact No. 0 size and an 80 mm length, this gauge is built for easy handling and fast pass/fail checks in tight spaces.

Ideal for routine quality control and in-process checks, this Go-No-Go gauge simplifies threaded hole verification by providing immediate, objective results. Its left-hand thread design ensures readings correspond to the actual components you’re testing, while the 2B specification supports consistent performance across batches. Built for durability, it stands up to daily use in demanding environments without compromising accuracy.

• Go/No-Go UNF verification: quickly determine if a threaded hole conforms to UNF specifications with a simple pass/fail check, reducing measurement ambiguity and rework.
• Left-Hand thread specialization: designed specifically for left-handed threads, ensuring readings reflect the real orientation of the component and preventing cross-reading errors.
• Rugged, ergonomic construction: robust ends and a knurled body provide a secure grip and long service life in busy workshops, even with repeated handling.

Using the JBO thread plug gauge helps streamline inspections, shorten setup times, and improve measurement reliability across production lines. It supports faster quality decisions, better traceability, and more consistent threaded assemblies from lot to lot.
