Thread Plug Gauge UNF 3/8‑24, ANSI/ASME B1.1 — Hardened Gauge Steel (Metav IndustryLine)

The Thread Plug Gauge UNF 3/8‑24 is a precision inspection gauge for verifying internal UNF threads to ANSI/ASME B1.1 standards, intended for workshop and production quality control.

• Thread plug gauge 3/8‑24 UNF ANSI B1.1
• Hardened gauge steel construction
• Tolerance class 2B for dimensional control
• Right‑hand thread, 24 TPI

Fast, standards‑based verification that reduces rework

The gauge is manufactured to match ANSI/ASME B1.1 thread geometry, making it a reliable reference for acceptance testing during incoming inspection and in‑process checks. With a defined tolerance class 2B, the tool provides a clear pass criterion for internal threads, which simplifies decision making on the shop floor and reduces costly rework. The hardened construction ensures wear resistance, so the reference dimension remains stable through repeated use.

Simple handling and quick application in production workflows

Designed as a compact inspection implement, the plug gauge features a 3/8‑inch nominal size with 24 threads per inch, allowing rapid tactile checks of internal threads commonly found on fittings, connectors and hydraulic components. At approximately 0.1 kg the gauge is easy to handle, enabling frequent sampling without fatigue. The combination of clear thread form and repeatable geometry supports consistent quality control and traceable inspection routines.

Durable build and clear traceability for long service life

Constructed from hardened gauge steel, the inspection plug offers robustness against shop hazards and maintains dimensional integrity over many cycles. The right‑hand thread and standard pitch are optimised for typical UNF applications. Supplied under the Metav IndustryLine portfolio, the item benefits from the brand's quality‑filter approach in Emmerich and its reputation for dependable supply. This makes the gauge a practical investment for workshops and production lines seeking reproducible thread inspection.

FAQ

What standard does the gauge conform to?
The Metav IndustryLine thread plug gauge M315.922.F is manufactured to ANSI/ASME B1.1 specifications for UNF thread form.

Is the tool suitable for production spot checks?
Yes. The plug gauge is intended as a repeatable inspection reference for routine checks in production and incoming inspection.

What does tolerance class 2B mean for internal threads?
Tolerance class 2B denotes the standard internal thread fit under ANSI practice; the gauge reflects that class to assess whether a thread meets acceptance criteria.

Can this gauge be used on left‑hand threads?
No. This specific gauge has a right‑hand thread form and is intended for right‑hand internal threads with 24 TPI.

How is durability ensured for workshop use?
Durability is achieved through hardened gauge steel construction, which resists wear and preserves the reference geometry over many inspection cycles.
