Thread Ring Gauge UNF NO‑GO 9/16 x 18, 2A — Metav IndustryLine

A Thread Ring Gauge UNF NO‑GO 9/16 x 18 for fast verification of external UNF threads to ANSI/ASME B1.1 tolerances, designed for shop‑floor and inspection‑bench use

• NO‑GO for UNF 9/16×18 threads
• Hardened gauge steel construction
• ANSI/ASME B1.1/B1.2 compliance
• Tolerance class 2A accuracy

Fast, fail‑safe thread control on the shop floor

A NO‑GO ring provides a direct, unambiguous check against oversize external threads: if the ring does not enter, the part conforms to the maximum material limits. This simple pass/fail method reduces cycle time in production and removes interpretation from go/no‑go decisions. The gauge is optimised for routine checks where speed and repeatability are required, delivering a tangible reduction in rework and scrap during serial manufacture.

Built for repeatability and long service life

Manufactured from hardened gauge steel, the ring is dimensionally stable under repeated use and resists surface wear that would otherwise affect accuracy. The compact mechanical design and balanced mass ensure consistent engagement with the mating thread, which supports repeatable inspection results over long production runs. This durability translates into lower lifecycle cost and predictable maintenance intervals for metrology programmes.

Standards alignment that simplifies conformity checks

Engineered to the ANSI/ASME B1.1/B1.2 thread form and specified 2A tolerance class, the ring matches common UNF external thread requirements. The UNF 9/16×18 designation and right‑hand thread configuration make the gauge immediately applicable to fastener and component inspection tasks within North American and international supply chains. Conformity to the standard means inspection records are directly comparable between suppliers and customers.

Integrates cleanly into inspection processes

The ring's straightforward geometry allows rapid bench mounting or handheld checks as part of pre‑assembly or incoming inspection routines. Its lightweight construction and compact profile support ergonomic handling during repetitive checks, while the clear pass/fail behaviour aids documentation and traceability in quality systems. For tailored advice on implementing this gauge in specific workflows, Metav Werkzeuge’s technical team can provide guidance and matching accessories.

FAQ

What does NO‑GO mean in practice for inspection?
A NO‑GO ring is used to confirm that an external thread does not exceed the maximum material condition; the ring must not enter if the thread is within tolerance. The Metav IndustryLine NO‑GO ring provides an immediate pass/fail outcome for this check.

Which thread standard and class does this gauge follow?
The ring is manufactured to ANSI/ASME B1.1/B1.2 and specified for 2A external thread tolerance, covering UNF 9/16×18 profiles.

Is the gauge suitable for high‑volume production checks?
Yes — the hardened gauge steel construction and compact form support frequent use on the shop floor and in inspection benches without rapid wear.

How is thread direction identified on the gauge?
This ring is supplied with a right‑hand thread configuration as standard for UNF 9/16×18 applications.
