Thread Plug Gauge UNC GO, No. 8 x 32 (ANSI/ASME B1.1 / 2A) — Metav IndustryLine

A thread plug gauge UNC GO No. 8 x 32 designed for quick go/no-go verification of external UNC threads in production and inspection settings.

No. 8 x 32 UNC GO thread plug gauge
Hardened gauge steel for long service life
Manufactured to ANSI/ASME B1.1/B1.2 standards
Tolerance class 2A for external threads

Consistent acceptance testing that reduces rework

A calibrated inspection routine starts with clear go/no-go criteria. This thread plug gauge is intended as a simple, repeatable check during incoming inspection, setup and final quality control to confirm that external UNC threads meet the lower acceptance limits. The GO-only design allows rapid assessment: the GO gauge must enter the thread smoothly to indicate conformity, which reduces subjective judgements and helps lower scrap rates. By standardising the acceptance step, process throughput becomes more predictable and traceable.

Built to match industry interchangeability requirements

Designed to the ANSI/ASME B1.1/B1.2 specification and classified 2A, the gauge reflects the tolerances expected for external UNC threads. The designation No. 8 x 32 denotes a nominal size No. 8 with 32 tpi (threads per inch), a common specification in imperial fastener systems. Knowing the tolerance class and thread pitch allows straightforward integration with inspection protocols and documentation workflows; these measurable parameters support compliance reporting and reduce ambiguity in production decisions.

Durable construction for regular workshop use

Manufactured from hardened gauge steel, the plug gauge is dimensionally stable and resists wear under routine handling, extending the interval between replacements. The compact form and modest weight make it suitable for bench inspection or portable quality checks at the machine centre. For traceability and inventory control the gauge is listed under SKU M315.947 and GTIN 4054469180083, enabling simple identification in procurement and quality records. Simple care—cleaning and light oiling after use and storage in a protective sleeve—preserves accuracy and surface condition.

FAQ

What does a GO thread plug gauge check?
The GO plug gauge verifies that an external UNC thread meets the minimum material and dimensional limits; the Thread Plug Gauge UNC GO, No. 8 x 32 should enter the thread smoothly to confirm acceptance.

Which standard and tolerance class apply to this gauge?
This gauge is manufactured to ANSI/ASME B1.1/B1.2 and conforms to tolerance class 2A for external threads.

What material is the gauge made from?
The gauge is produced from hardened gauge steel, chosen for wear resistance and dimensional stability in routine inspection use.

How is the size No. 8 x 32 interpreted?
No. 8 indicates the nominal fastener size and 32 tpi means 32 threads per inch; this combination defines the thread form the gauge is intended to verify.

Is this gauge suitable for production-line inspection?
Yes—the Metav IndustryLine Thread Plug Gauge No. 8 x 32 (SKU M315.947) is intended for regular use in production and incoming inspection to provide quick, repeatable go/no-go checks.
