Thread ring gauge M40 × 1 mm (Go) — Go ring gauge, hardened gauge steel (Metav IndustryLine)

The Thread ring gauge M40 × 1 mm (Go) is a precision Go ring for rapid verification of metric ISO fine external threads (right-hand), intended for shop-floor quality control and incoming inspection.

• Hardened gauge-steel construction
• Conforms to DIN 13, 6g
• For M40 × 1 mm metric fine threads
• Right-hand Go ring for quick pass/fail checks

Rapid, unambiguous pass/fail inspection for production lines

The Go ring is designed to provide a clear and immediate assessment of external threads: if the tested part enters the ring smoothly, the thread is accepted; if not, it is rejected. This straightforward check reduces inspection time compared with full dimensional measurement and supports efficient throughput in batch production. With conformity to DIN 13, 6g and an exact M40 × 1 mm pitch, the gauge ensures that checked components comply with the expected tolerance class, preserving interchangeability and avoiding assembly failures. The functional simplicity of a Go ring converts technical accuracy into operational speed.

Robust construction that minimises wear and handling uncertainty

Manufactured from hardened gauge steel, the ring resists wear and maintains dimensional stability over many cycles, which lowers the frequency of replacement and reduces downtime. Hardened tool steel provides consistent seating and repeatable tactile feedback during inspection, which helps operators make reliable judgements without complex instrumentation. The compact, solid geometry of the ring also simplifies storage and handling on the shop floor, while the inherent mass and finish of the material help to avoid burr formation that could otherwise affect results.

Practical integration into quality systems and traceability

A gauge of this type suits both incoming inspection and in-process control. The straightforward nature of a Go ring makes it ideal as a first-line control in assembly sequences and as part of a layered quality strategy where quick decisions are required. Identification data such as the item code and GTIN support traceability in inventory and audit processes, allowing the gauge to be recorded in inspection logs or a calibration schedule. As a Metav IndustryLine product, the ring complements a broader precision portfolio aimed at delivering reliable measuring tools for industry and trade.

FAQ

What does the Go designation mean for this thread ring?
The Go designation indicates that the ring is manufactured to allow a correctly produced external thread to pass; the Thread ring gauge M40 × 1 mm (Go) checks that the part does not exceed the maximum material condition for the specified tolerance class.

Can this ring be used in serial production inspection?
Yes — the hardened construction and simple pass/fail function make the gauge suitable for fast, repetitive checks in serial production and incoming inspection routines.

Which tolerance class does the gauge correspond to?
The gauge conforms to DIN 13, 6g, matching the common metric ISO fine-thread tolerance for many engineering applications.

Is the gauge suitable for both right- and left-hand threads?
This specific ring is for right-hand threads; left-hand versions require a dedicated ring produced with the opposite helix.

How should the gauge be stored to maintain accuracy?
Store the ring in a dry, clean environment and protect it from shocks and contamination; the hardened gauge steel resists wear, but careful handling prolongs service life.
