The JBO Thread Plug Gauge is a precision go-no-go tool designed to verify trapezoidal thread holes with speed and reliability. Built for engineers, machinists, buyers, and quality teams across manufacturing, automotive, and aerospace, it delivers quick acceptance checks to ensure threaded components meet exact size and tolerance. This right-hand plug gauge is sized for Tr. 16 x 4 with a 7H tolerance, aligned to standard trapezoidal thread specifications and Unified thread standards. Its go/no-go design makes it easy to identify conforming versus non-conforming holes at a glance, streamlining quality control in busy shops.

• Go-No-Go design for fast verification: Quickly determine whether a hole’s trapezoidal thread meets spec, reducing inspection time and minimizing guesswork in setup and assembly.
• Right-hand trapezoidal sizing, 7H tolerance (Tr. 16 x 4): Precise, standard-compliant dimensions that deliver repeatable pass/fail results for reliable quality checks.
• Rugged, user-friendly construction: Knurled grip and precision-machined ends provide secure handling and durable performance in demanding workshop environments.

Use the JBO Thread Plug Gauge to validate thread holes before assembly, cut down on rework, and maintain consistent quality across production runs. Its straightforward operation supports faster setup, fewer downtime delays, and confident decisions during inspections—helping you keep projects on schedule and within specification.
