UNEF NOGO Thread Ring Gauge 7/16 x 28 (ANSI/ASME B1.1) — 2A, hardened gauge steel (Metav IndustryLine)

The UNEF NOGO Thread Ring Gauge 7/16 x 28 is a right-hand NOGO control gauge designed for verifying external threads in production and inspection to ANSI/ASME B1.1 tolerances.

• Right-hand NOGO thread control
• Conforms to ANSI/ASME B1.1 tolerances
• Hardened gauge steel for long life
• Tolerance class 2A for precise rejection

Faster, reliable rejection with standardised tolerances

The NOGO ring performs a single, unambiguous check: if the ring does not assemble, the thread is accepted within the specified maximum material condition. Built to tolerance class 2A and matched to ANSI/ASME B1.1, this gauge provides measurable control for 7/16" threads with 28 tpi. Using a purpose-made NOGO eliminates subjective judgement during inspection and shortens cycle times on the shop floor, improving throughput and reducing the risk of shipping oversize threads.

Durable construction for consistent measurement over time

Manufactured from hardened gauge steel, the ring offers excellent wear resistance and stable geometry under repetitive use. The material choice and heat treatment preserve the thread form so that rejection thresholds remain consistent across thousands of cycles. Physical robustness reduces the need for frequent replacement and supports predictable maintenance intervals, which benefits production planning and lowers total cost of ownership.

Designed for pragmatic inspection workflows

As a dedicated NOGO ring gauge for external threads, this tool integrates directly into assembly checks, incoming inspection and set-up verification. The clear pass/fail logic speeds operator decisions and supports traceable quality routines. For batch inspection, the gauge complements go gauges and measurement equipment to create a layered control strategy that cuts rework and scrap. The compact, single-purpose design also simplifies storage and handling in busy inspection bays.

FAQ

What does NOGO mean for a thread ring gauge?
NOGO indicates the rejection gauge: if the NOGO ring does not assemble on the external thread, the component meets the maximum material condition and is acceptable under the specified tolerance.

Which standard does this ring follow?
The ring is produced to ANSI/ASME B1.1/B1.2 standards and is specified as tolerance class 2A for external thread acceptance criteria.

Is this a right-hand or left-hand thread gauge?
This NOGO ring is manufactured for right-hand threads and is intended to control external right-hand UNEF threads.

What thread size and pitch does the gauge control?
The gauge is for 7/16" diameter threads with 28 tpi (threads per inch), matching common UNEF fine-thread applications.

What is the material and durability of the gauge?
Made from hardened gauge steel, the ring is designed for wear resistance and stable geometry to ensure repeatable reject limits over many inspection cycles.
