Asimeto Plug Thread Gauge (D/E) - Metric - Right Hand - 6H - M39 x 4

The Asimeto Plug Thread Gauge (D/E) — Metric, Right Hand, 6H, M39 x 4 — is a precision go/no-go tool crafted for reliable internal thread verification. Designed for machinists, inspectors, and quality teams, it delivers repeatable checks that help keep every part within spec.

• Dual-end design (D/E): Two ends optimized for go/no-go checks on internal M39 x 4 threads with a right-hand configuration.
• Thread size and tolerance: M39 x 4, 6H coarse metric tolerance for dependable thread verification.
• Construction and finish: Hardened tool steel body with a knurled texture for secure handling and long-lasting use.
• Series and scope: 680 Series metric plug gauges tuned for coarse thread checks in industrial settings.
• Durability: Heat-treated and corrosion-resistant surfaces to withstand frequent QC cycles.
• Precision manufacturing: Tight-tolerance production ensures repeatable pass/fail results across parts.

By using the Asimeto plug gauge, you can confirm thread engagement with confidence, speed up acceptance testing, and reduce the risk of misfits in assemblies. The durable construction handles daily shop use, while the go/no-go design clearly indicates whether an internal thread meets the 6H tolerance for M39 x 4. Whether you're inspecting incoming parts, performing in-process checks, or validating repair work, this gauge delivers consistent, actionable results that support tighter quality control and smoother production flows.
