Thread Ring Gauge M30 × 3.5 mm (DIN 13, 6g) — Metav IndustryLine

The Thread Ring Gauge M30 × 3.5 mm is a hardened limit gauge for go/no-go verification of metric ISO regular threads (right-hand), designed for inline quality control and workshop use.

• Hardened gauge steel construction
• DIN 13, tolerance grade 6g
• For M30 x 3.5 mm metric ISO threads
• Right-hand thread limit gauge

Accurate tolerancing for reliable production control

The ring gauge performs rapid go/no-go checks to verify the external threads of machined parts against the DIN 13 standard and the 6g tolerance grade. By confirming major diameter and pitch conformity in a single action, the device reduces measurement cycle time and avoids time‑consuming secondary inspections. The clear pass/fail concept makes the gauge ideal for batch control and repeated checks on the shop floor, supporting measurable improvements in process throughput and scrap reduction.

Robust design reduces maintenance and downtime

Manufactured from hardened gauge steel, the gauge resists wear from repeated engagement with threaded parts and maintains dimensional stability under frequent use. The hardened material and precise manufacturing process ensure consistent contact geometry for each verification, which lowers the need for adjustment and extends service life. For standard quality-control routines, the ring gauge offers a pragmatic combination of durability and low maintenance, ensuring reliable limit checks shift after shift.

Practical applications and inspection integration

This ring gauge suits production, assembly and incoming‑goods inspections where conformity to metric ISO threads must be confirmed quickly. The gauge complements optical or digital measurement systems by providing a fast binary check that flags non-conforming parts before assembly. Its compact, single‑piece design facilitates storage and handling in tool cabinets or inspection stands, and it is compatible with standard fixture layouts for rapid deployment in existing inspection workflows.

FAQ

What does the 6g tolerance mean for inspection?
The 6g grade defines the permissible manufacturing tolerance for the external thread; the Thread Ring Gauge M30 × 3.5 mm (Metav IndustryLine, SKU M315.230) checks that the part falls within that specification by a direct go/no-go test.

Is this gauge suitable for series production use?
Yes, the hardened construction and limit‑gauge principle make this ring gauge suitable for routine series inspections and in‑line quality checks where rapid pass/fail decisions are required.

Does the gauge indicate pitch errors as well as diameter deviations?
The ring gauge primarily verifies the fit of the external thread form against the nominal profile (including pitch and major diameter as part of the limit check); gross pitch errors that prevent proper engagement will be indicated by a fail result.

Can this gauge be used for left-hand threads?
This specific item is manufactured for right‑hand threads. For left‑hand versions, request the appropriate ring gauge variant from Metav IndustryLine.

How should the ring gauge be stored between uses?
Store the gauge clean and dry, ideally in a protective pouch or drawer, to prevent contamination and corrosion; periodic visual inspection will ensure continued reliable operation of the Metav IndustryLine gauge.
