The JBO Thread Ring Gauge (GO) - Metric Coarse - Right Hand - 6g - M33 x 3.5 is a precision inspection tool designed to verify external metric threads. It’s ideal for engineers, buyers, tradespeople, hobbyists, and quality control teams who need fast, reliable checks to confirm parts thread correctly and mate with corresponding components.

Built from hardened steel for durability, this GO gauge delivers reliable performance in busy workshops and QC labs. Its straightforward go condition provides quick, confident acceptance of parts that meet the M33 x 3.5 coarse-thread standard, helping reduce guesswork and improve inspection consistency.

• Exact M33 x 3.5, right-hand GO specification: Delivers a precise go condition for the external thread, enabling fast, reliable verification of thread engagement and mating accuracy with standard components.
• 6g external thread tolerance: Aligns with ISO metric coarse threading to ensure consistent acceptance criteria across parts and suppliers, reducing variability in assembly.
• Hardened steel construction: Wear- and dent-resistant design that preserves accuracy through heavy use, delivering long service life in demanding QC environments.

Using this gauge in your workflow helps you quickly validate parts, minimize downtime, and prevent mismatches that slow production. It supports accurate supplier qualification, tighter quality control, and a smoother assembly process by ensuring every M33 x 3.5 threaded connection meets the standard.
