Designed for metric coarse threads, the JBO Thread Plug Gauge provides precise go/no-go checks for M33 x 3.5 holes. With a left-hand configuration, it supports specialized machining setups and offers fast, reliable inspections for engineers, machinists, and quality teams.

• Go/No-Go evaluation for M33 x 3.5, 6H: Quickly confirm hole acceptance by distinguishing good from out-of-tolerance threads, reducing guesswork and rework on the shop floor.
• Hardened steel construction for long life: Built to withstand daily use in demanding environments, delivering enduring accuracy and value over time.
• Left-hand threading compatibility: Supports inspection in left-handed thread applications, ensuring reliable measurements in specific manufacturing setups.

With this gauge in your toolkit, you’ll perform quick, repeatable thread checks, cut downtime, and improve overall assembly reliability. The combination of metric coarse thread focus, left-hand compatibility, and a durable hardened-steel body means you can rely on consistent results across many jobs and maintain tight tolerances with less effort.
