Introducing the Asimeto Plug Thread Gauge (D/E) — a precision metric plug gauge designed for engineers, machinists, and quality teams that require reliable internal thread verification. Part of the 680 Series, this right-hand, coarse-thread gauge delivers consistent measurements for M18 x 2.5 applications.

• End Configuration: Dual-end gauge with M18 x 2.5 right-hand threads on each end, designed for quick internal thread checks.
• Series and Tolerance: 680 Series, metric coarse 6H tolerance for dependable fit and measurement stability.
• Material & Build: Hardened steel body with knurled surface for secure grip, built to endure daily workshop use.
• Precision Machining: Precisely machined threads and surfaces to maintain accuracy over time.
• Application: Ideal for quality control in machining, assembly, and maintenance where internal threads must meet spec.

With this plug gauge, you gain fast, repeatable checks of internal M18 x 2.5 threads, reducing guesswork and part rework. The robust construction and precise 6H tolerance ensure long-term reliability in busy production environments, helping you achieve consistent first-pass yields, tighter process control, and confident acceptance of threaded components in automotive, industrial, and aerospace applications.
