Thread ring gauge M8 x 0.5 (GO) — DIN 13, 6g

A Thread ring gauge M8 x 0.5 (GO) for quick conformity checks of right-hand metric ISO fine threads in production and inspection environments

• GO thread ring gauge M8 x 0.5, metric fine thread
• Hardened gauge steel for durable wear resistance
• Conforms to DIN 13, tolerance 6g
• Right-hand thread, immediate go/no-go result

Rapid, reliable go/no-go inspection for fine threads

A dedicated GO gauge delivers an unambiguous pass/fail decision at the point of inspection, removing interpretation from routine checks. The ring is specified for M8 x 0.5 metric fine threads and manufactured to DIN 13 with tolerance class 6g, which defines the target form and limits for mating external threads. Using a ring gauge in the shop or at the inspection bench shortens cycle time: a simple attempt to engage the ring confirms conformity, enabling efficient sorting of acceptable parts and early detection of production drift.

Robust construction reduces downtime and rework

Manufactured from hardened gauge steel, the ring resists wear from repeated engagement and retains its conformity longer than untreated components. The material choice and heat treatment reduce the need for frequent replacement, which in turn lowers maintenance intervals and cost per inspection. The compact design and solid construction make this a practical tool for daily use in quality control stations where reliability and repeatability matter.

Standards-based measurement supports traceable quality processes

Compliance with DIN 13 and the specified 6g tolerance class ensures the gauge aligns with common engineering standards for metric ISO fine threads. This alignment facilitates clear communication between production and quality departments and supports traceable inspection protocols. The GO ring is intended for direct comparative checks; it confirms the minimum acceptable size and form of mating external threads, forming part of a robust quality assurance workflow.

Simple handling for efficient workflow integration

The ring's right-hand threading and ergonomic size make it straightforward to use at the bench or inline. As a handheld inspection tool, it minimises setup time compared with dimensional measurement methods and is suited to rapid checks during batch production. For specific applications or thread system questions, the Metav technical team can provide advice on integrating ring gauges into existing inspection routines and recommend complementary control measures.

FAQ

What is the primary use of this ring gauge?
The thread ring gauge M8 x 0.5 (GO) is used for quick pass/fail inspection of right-hand metric ISO fine external threads to confirm they meet the required form and minimum dimensions.

What does "GO" mean on a ring gauge?
GO indicates that the ring is the accept limit; if the mating external thread engages the GO ring, the part is within the acceptable lower size and form constraints defined for the thread.

Which standards and tolerance class apply to this gauge?
This ring is made to DIN 13 and the tolerance class 6g, providing compatibility with standard metric ISO fine-thread specifications.

Can this gauge be used for left-hand threads?
No, this specific ring is manufactured for right-hand threads only; left-hand thread inspection requires a corresponding left-hand gauge.

How should the gauge be stored and maintained?
Keep the ring clean and dry, inspect it visually for wear before use, and store it in a protective tray or box to preserve the hardened surface and thread form.
