Sized for M39 x 2 right-hand threads, it’s a trusted tool for machinists, inspectors, and engineers in manufacturing environments.
- Series: 685 Series GO ring gauge for Metric Fine 6g precision checks
- Size: M39 x 2, right-hand thread configuration for common metric assemblies
- Material: High-quality steel designed to endure daily shop use and resist wear
- Design: Machined ring with a knurled outer edge for secure handling and quick setup
- Intended Use: Ideal for go/no-go validation of cylindrical parts and mating threads in automotive, aerospace, and engineering workflows
This gauge delivers fast, accurate go checks to confirm parts meet the lower limit of the specified thread size, helping reduce rework and ensure consistent mating performance in production lines. The durable steel construction stands up to routine calibration and handling, while the knurled rim makes it easy to grip and rotate during inspections.
