The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, specifically M28 x 2. It provides quick, reliable go/no-go checks to verify internal threads in tapped holes, helping ensure parts fit together exactly as designed.

Crafted from hardened steel with a textured knurled grip, this Right Hand gauge stands up to daily shop use and resists wear over time. The Go/No-Go ends let you determine acceptance and rejection points in a single measurement, speeding up setup and inspection without guesswork.

• Go/No-Go verification at a glance: Dual ends enable immediate assessment of whether a hole meets the M28 x 2 specification, reducing inspection time and rework.
• Rugged, wear-resistant construction: Hardened steel and a knurled body stand up to heavy use, maintaining accuracy even in oily or dusty environments.
• Precisely matched to 6H tolerance: Ensures consistent, reliable go/no-go limits for metric fine threads, improving batch-to-batch consistency.

By providing fast, dependable thread checks, the JBO Thread Plug Gauge helps you streamline QA workflows, reduce assembly delays, and improve overall part interchangeability. Its durable build and precise tolerance translate into fewer rejects, lower downtime, and greater confidence in every threaded connection.
