The Asimeto Ring Thread Gauge (NoGo) is a precision metric tool designed for engineers, machinists, and quality teams who need reliable verification of external threads. Built for right‑hand M38 x 1.5 threads in the 6g tolerance class, it helps ensure fasteners meet exact dimensional limits before use.

• Nominal size: M38 x 1.5 external thread gauge
• Tolerance class: 6g for tight, accurate pitch diameter control
• Designation: NoGo gauge used to confirm the thread pitch diameter does not exceed the maximum limit
• Orientation: Right‑hand threading compatible with standard metric fasteners
• Series: 686 Series, crafted for precision and long‑lasting performance
• Construction: High‑quality metal build designed for repeated use in workshop and inspection environments

Using this NoGo gauge during assembly and inspection ensures only properly sized M38 x 1.5 threads are accepted, reducing the risk of loose fits, cross‑threading, or failed connections. The gauge supports consistent fastener quality, simplifies go/no-go checks, and provides a reliable reference for routine maintenance, production quality control, and supplier audits. Its design is purposefully straightforward to integrate into existing measurement workflows, delivering trustworthy results with every check.
