The JBO Thread Plug Gauge (GO) - Metric Fine - Right Hand - 6H - M85 x 1.5 is a precision inspection tool designed to quickly verify threaded holes meet exact size and thread form. It’s ideal for machinists, quality engineers, toolmakers, and assembly technicians who rely on accurate go checks to confirm proper threading before assembly.

Crafted from hardened steel, this GO gauge offers exceptional durability and wear resistance for daily use in demanding workshop environments. Its straightforward, compact design makes it easy to perform fast, reliable checks, helping quality control teams maintain consistent standards across parts and lots.

• Easy Go/No-Go verification: Quickly determine if the threaded hole accepts the GO gauge, speeding QA checks and reducing guesswork.
• Durable, wear‑resistant construction: Hardened steel withstands repeated testing, preserving accuracy over many inspections.
• Matched to M85 x 1.5 metric fine threads (6H, Right Hand): Ensures reliable, repeatable checks for standard right-hand holes with the precise fine pitch.

Using the JBO GO gauge simplifies threaded-hole inspection, helping you improve workflow, reduce inspection time, and maintain consistent results across production runs. Its durability and exact sizing give teams confidence that components will assemble correctly and meet required specifications, even in high-volume or precision-focused environments.
