Thread gauge ring M39 x 4 mm — DIN 13 (6g), hardened gauge steel (Metav IndustryLine)

A Thread gauge ring M39 x 4 mm for fast verification of external metric ISO threads in workshop inspection and quality control

• Hardened gauge steel construction
• Conforms to DIN 13 tolerance 6g
• For M39 x 4 mm metric ISO threads
• Right-hand thread verification

Ensure compliance with recognised thread standards

The ring is manufactured to DIN 13 with tolerance class 6g, giving a clear, reproducible reference for external metric ISO threads. Conformity to this standard simplifies acceptance criteria in production and inspection environments, because the tolerance class defines the maximum permissible deviations for the external thread form. Using a standardised reference reduces interpretative variance between operators and speeds up go/no-go decisions during batch checks, improving throughput and traceability.

Built for repeatable performance and long service life

Made from hardened gauge steel, the component resists wear under frequent use and preserves its functional dimensions over time. Heat-treated surfaces maintain form stability during repeated engagement with screw threads, which means fewer replacements and consistent results across many inspection cycles. The robust material and precise machining reduce the risk of false rejects, supporting efficient quality assurance routines in metalworking and assembly operations.

Practical application in production and workshop inspection

Designed for direct inspection of external threads, the ring serves as a quick acceptance tool on the shop floor or in the quality lab. Intended for regular checks of externally threaded parts, it enables fast decisions on lot conformity and helps identify out-of-tolerance parts before further processing. The compact, easily storable form factor fits routine inspection workflows and integrates with standard quality-control procedures without requiring specialist equipment.

Identification and traceability for inventory and documentation

The gauge is supplied under article number M315.239 and is marked for clear identification to support inventory control and inspection records. Including a unique identifier simplifies documentation of inspection results and replacement scheduling. For companies that require product traceability in audits, the clear marking and industry-standard specification make it straightforward to record which instrument was used for a given batch inspection.
