Thread ring gauge UNEF GO, 5/8‑24 ANSI/ASME B1.1 – 2A (Metav IndustryLine)

The Thread ring gauge UNEF GO, 5/8‑24 ANSI/ASME B1.1 – 2A is a hardened gauge steel GO ring designed for quick, reliable verification of right‑hand external threads to ANSI/ASME tolerances.

• Hardened gauge steel construction
• Right‑hand 5/8‑24 UNEF thread form
• Tolerance class 2A to ANSI/ASME B1.1
• Compact, shop‑ready GO ring gauge

Reliable conformity for inspection and process control

The ring is manufactured to match ANSI/ASME B1.1 requirements, delivering a GO check that confirms dimensional compliance without ambiguity. Built as a GO ring gauge, it provides a binary, rapid verification: a pass indicates the external thread meets the specified form and size within the 2A tolerance class, which supports consistent quality control and reduces rework rates on production lines. This makes the gauge suitable for routine incoming inspections and final part validation where traceable, repeatable checks are essential.

Robust material and workshop longevity

Constructed from hardened gauge steel, the gauge resists wear from repeated engagement with threaded parts and maintains dimensional stability under normal workshop conditions. The use of hardened tool steel ensures the checking tool sustains long service life, preserving the reference profile and reducing the need for frequent replacements. As a compact verification tool, the ring delivers mechanical reliability and low maintenance effort, supporting efficient inspection workflows and minimising downtime.

Practical application and handling benefits

The gauge is specified for a 5/8‑24 UNEF external thread with right‑hand orientation and 24 threads per inch, suited to components where fine‑pitch UN series threads are required. Its compact form factor allows quick handheld checks at the machine or in the inspection bench, enabling rapid decision making during production. For organisations operating to recognised thread standards, this ring facilitates straightforward conformity checks and integrates easily into quality procedures and inspection plans.

FAQ

What does tolerance class 2A mean for this gauge?
Tolerance class 2A denotes the external thread tolerance band; the Thread ring gauge UNEF GO, 5/8‑24 ANSI/ASME B1.1 – 2A checks that the external thread falls within the acceptable dimensional limits for class 2A as defined in the standard.

Is this gauge suitable for fine‑pitch UN threads?
Yes, the ring is specified for a 5/8‑24 UNEF form, which is part of the Unified Extra Fine series and intended for fine‑pitch external threads.

What material is the gauge made from and why does it matter?
The gauge is made from hardened gauge steel, chosen for wear resistance and dimensional stability so that the GO profile remains reliable through repeated use.
