This JBO GO thread ring gauge provides a straightforward way to check external threads on parts sized M80 x 6 with metric fine right-hand threading. Built for use in machine shops, quality departments, and assembly lines, it confirms whether threaded components fall within the 6g tolerance so only conforming parts move forward.

• Hardened steel construction: Delivers long service life even when used daily in busy inspection areas, reducing the need for frequent replacements.
• Clear GO acceptance: Quickly identifies parts that meet the upper thread limit without requiring additional measuring tools or complex setups.
• Knurled outer surface: Gives a secure hold during handling, helping inspectors work faster and more comfortably on repetitive checks.

By catching thread issues early, this gauge keeps production moving smoothly, cuts down on rework, and supports consistent output that meets customer and industry specifications.
