The JBO Thread Ring Gauge (GO) - Metric Fine is a precision tool designed to verify external threads on metric-fine sizes. It is tailored for left-hand threads, specifically M11 x 0.5 with a 6g tolerance class, making it ideal for quality control, machining, and assembly processes that demand accurate, repeatable checks. Crafted from hardened steel, it delivers durable performance in demanding shop environments.

• Precision GO check for M11 x 0.5 left-hand threads: Precisely finished to verify external thread diameters against standard limits, helping ensure components meet spec on the first check and reduce rework.
• Hardened steel construction: Provides exceptional wear resistance and dimensional stability in busy workshops, delivering long-lasting service life even with frequent use.
• User-friendly inspection with clear pass/fail decisions: Designed for quick, straightforward checks that require minimal training, speeding up quality control and reducing production downtime.

Used in incoming inspection, in-process checks, and final assembly, this gauge speeds up quality control by enabling quick verdicts on thread acceptance. Its durable construction and precise tolerances help maintain consistent measurements across shifts, reducing rework and ensuring parts meet spec on every lot. With the JBO Thread Ring Gauge (GO) in Metric Fine, you gain reliable, repeatable checks that support confident purchasing, better supplier control, and smoother production flow.
