JBO Thread Plug Gauge (GO) - BSW - Right Hand - Medium Class - 1 3/4 x 5

The JBO Thread Plug Gauge (GO) is a precision inspection tool designed to verify internal British Standard Whitworth (BSW) right-hand threads. Sized for 1 3/4 x 5 and offered in a Medium Class tolerance, this go gauge helps manufacturers, automotive shops, and aerospace suppliers quickly confirm that threaded holes meet the required size and pitch for reliable mating and performance.

With its Go-design, you get immediate pass/fail feedback—holes that accept the gauge are within tolerance, while others are easily identified for correction. Built for daily use in busy shops, the gauge delivers consistent results across production runs and helps keep assemblies moving smoothly.

• Go Gauge design for fast conformance checks: The GO end provides immediate pass/fail feedback, enabling quick determination whether a threaded hole matches the 1 3/4 x 5 BSW right-hand specification and reducing inspection time.
• BSW Right-Hand thread match (1 3/4 x 5): Precisely sized for British Standard Whitworth right-hand internal threads, ensuring correct mating with corresponding fasteners and preventing mismatches in assemblies.
• Durable, easy-to-hold construction: Knurled exterior and robust build provide a secure grip, long service life, and repeatable measurements in daily shop use.

Using the JBO Thread Plug Gauge (GO) helps you verify thread quality quickly, streamline quality checks, and prevent costly rework by catching out-of-spec holes before assembly. Its precise sizing and reliable go/no-go feedback improve workflow, boost confidence for engineers and technicians, and support consistent results across batches in manufacturing, automotive, and aerospace environments.
