Thread ring gauge UNEF GO, 9/16 x 24 ANSI B1.1 / 2A — GO ring gauge, hardened gauge steel, Metav IndustryLine

The Thread ring gauge UNEF GO, 9/16 x 24 ANSI B1.1 / 2A is a hardened gauge‑steel GO ring for the verification of external 9/16‑24 UNEF threads to the ANSI/ASME B1.1 2A tolerance class, intended for workshop and production use

• GO ring for 9/16 x 24 UNEF threads
• Manufactured to ANSI/ASME B1.1 standard
• Hardened gauge steel for long service life

Certified conformity for consistent inspection results

The GO ring provides a clear, standards‑based criterion for pass/fail checks, complying with ANSI/ASME B1.1 and the 2A tolerance class for external threads. This standardised approach removes ambiguity from routine inspections, enabling rapid decisions at the receiving dock or on the shop floor. By relying on a plain GO gauge instead of subjective visual assessment, process throughput and quality documentation are both improved.

Robust, wear‑resistant build that lowers running costs

Manufactured from hardened gauge steel, the ring resists everyday wear and maintains thread form during repeated engagement, reducing the need for frequent replacement. The compact 9/16‑24 UNEF size and a mass of approximately 0.2 kg make the gauge easy to handle while retaining the rigidity necessary for reproducible checks. The durable construction translates into fewer measurement interruptions and lower lifecycle cost for production testing equipment.

Designed for efficient integration into inspection routines

As a single‑criteria GO ring, this tool excels where a quick verification of external threads is required: incoming parts inspection, final assembly checks and spot checks in machining cells. The simple GO‑only check supports fast throughput and clear non‑conformance signalling; for more detailed assessment, supplementary thread measurement methods can be used in parallel. The gauge is supplied ready for immediate use and is suited to continuous inspection cycles in industrial environments.

FAQ

What does the 2A tolerance class mean for this gauge?
The 2A class indicates the gauge is manufactured to the common external thread tolerance for general engineering; the Thread ring gauge UNEF GO, 9/16 x 24 ANSI B1.1 / 2A verifies that external threads meet that standard.

Is this gauge suitable for fast incoming‑inspection checks?
Yes, the GO ring gauge M315.955.EF is designed for rapid pass/fail decisions during incoming inspection and in‑process control.

What material is the ring made from and why does it matter?
The ring is made from hardened gauge steel, providing wear resistance so the GO criterion remains stable over many cycles, ensuring repeatable thread verification.

Does this product check left‑hand threads?
No, this specific ring is for right‑hand UNEF threads as stated under special features; left‑hand thread checks require the corresponding left‑hand gauge.

Can this gauge be used to measure pitch or form exactly?
A GO ring provides a go/no‑go verification of thread acceptance rather than detailed pitch or flank‑form measurement; for dimensional analysis, supplementary measurement methods are recommended.
