The JBO Thread Ring Gauge (GO) is a metric coarse, right-hand GO gauge designed to verify external threads quickly and reliably. Sized for M18 x 2.5 with a 6e class, it helps quality teams, engineers, and machinists confirm that threaded parts meet exact specifications and will assemble correctly with mating fasteners.

Manufactured from hardened steel for excellent durability and wear resistance, this gauge is built to withstand daily use in inspection and production environments. Its clean, simple design includes a knurled outer surface for a secure, slip-free grip during checks.

• Precise metric coarse GO gauge for M18 x 2.5 threads: Ensures external thread diameters conform to the 6e class, enabling reliable fit with mating fasteners.
• Hardened steel construction for long life: Delivers outstanding durability and wear resistance to keep measurements accurate through heavy use.
• Ergonomic, user-friendly inspection tool: Knurled outer surface and straightforward geometry allow fast, repeatable checks with less guesswork.

This GO gauge helps you streamline quality control, reduce inspection time, and minimize return or rework by providing quick, confident pass/fail decisions on metric coarse external threads. With its durable construction and precise size, you can trust it to deliver consistent results across batches, support proper assembly with M18 x 2.5 fasteners, and uphold industry standards in manufacturing, machining, and assembly workflows.
