Precision NoGo thread ring gauge for metric external threads, tailored for M12 x 1.5 right-hand fasteners. Part of the 686 Series, it delivers reliable pitch diameter checks to support safe, correct assembly.

• Size and thread: M12 x 1.5 metric, right-hand external thread for standard fasteners.
• Tolerance class: 6g gauge tolerance ensures precise pitch diameter measurement for quality control.
• NOGO designation: NoGo gauge design that reveals oversized or out-of-tolerance threads when a fastener fails to pass through.
• Identification color: Red marking for quick reference identifying NoGo status in busy work environments.
• Standards alignment: Gauge dimensions aligned with DIN ISO 1502/ISO metric threading conventions for consistent inspection results.
• Construction quality: Built from high-quality gauge-grade material to withstand repeated use and maintain accuracy over time.
• Temperature reference: Calibrated with a standard 20°C reference to ensure stable measurements across environments.

This gauge helps machinists, quality inspectors, and maintenance technicians verify that external threads meet the maximum material limits before assembly. By confirming the pitch diameter stays within the 6g tolerance, it reduces the risk of cross-threading, improper fits, and rework, delivering faster, more reliable production and maintenance outcomes.
