The JBO Thread Plug Gauge (NoGo) is a precision inspection tool designed to verify internal threads against Unified thread standards. It’s ideal for manufacturers, automotive shops, and aerospace facilities that perform regular quality checks on threaded holes to ensure proper fit and function.

With its NoGo design, inspectors can quickly identify non-conforming threads, reducing misfits, rework, and production delays while supporting consistent, repeatable inspections.

• No-Go validation for fast pass/fail checks: Quickly confirms whether a threaded hole is within spec by blocking the entry of undersized or misfitted threads, speeding inspections and improving first-pass yields.
• UNS Right-Hand 1 3/4 x 8, 2B tolerance: Precisely sized for Unified standard threads, delivering repeatable measurements and reliable acceptance criteria across parts and batches.
• Durable, ergonomic construction: Knurled grip and robust body design provide secure handling in cramped spaces and withstand daily shop use for long service life.

Using the JBO Thread Plug Gauge (NoGo) provides faster, more reliable quality control. It helps you catch non-conforming holes before assembly, shortens inspection cycles, and improves overall workflow by delivering clear acceptance criteria and repeatable results across batches.
