Thread plug gauge UNF 1 3/8 x 12 ANSI B1.1 / 2B — hardened gauge steel, tolerance class 2B

The thread plug gauge UNF 1 3/8 x 12 ANSI B1.1 / 2B is designed for fast verification of internal UNF threads in production and inspection environments, offering a compact, robust check for thread acceptance.

• Hardened gauge steel construction
• ANSI/ASME B1.1 compliant thread standard
• Right-hand UNF 1 3/8-12, tolerance 2B
• Suitable for production inspection and QA

Rapid, standards-led assurance for UNF threads

The thread plug gauge provides an immediate, objective pass/fail check where conformity to ANSI/ASME B1.1 matters. Built to verify UNF 1 3/8‑12 internal threads at tolerance class 2B, the gauge simplifies acceptance testing by confirming thread form and basic tolerance without elaborate set‑ups. For manufacturing lines and inspection benches, this results in fewer ambiguous results, less rework and faster throughput — a clear efficiency gain for quality procedures where reproducibility is essential.

Durable construction for consistent repeatability

Manufactured from hardened gauge steel, the gauge resists wear and maintains form over repeated cycles, preserving repeatability in routine checks. The compact design and modest mass contribute to easy handling during repetitive inspections while the robust material reduces the need for frequent replacements. Where traceable measurement history is required, the stable performance of the gauge supports reliable record‑keeping and consistent acceptance criteria across batches.

Practical benefits for workshop and production quality control

Integrating this thread plug gauge into inspection workflows streamlines go/no‑go decision‑making and supports documented quality processes. The right-hand UNF specification and clear tolerance class 2B marking make it straightforward to match the gauge to component drawings and inspection plans. Used alongside calibrated measuring equipment, the gauge helps to reduce scrap rates and avoid assembly problems caused by out‑of‑tolerance threads, thereby protecting downstream operations and customer satisfaction.

FAQ

What does tolerance class 2B mean for internal threads?
Tolerance class 2B denotes the standard internal thread tolerance under ANSI/ASME B1.1 and indicates the gauge is intended for general engineering fits; the thread plug gauge UNF 1 3/8 x 12 ANSI B1.1 / 2B checks conformity to that class.

Is this gauge suitable for serial production checks?
Yes. The Metav IndustryLine thread plug gauge is robustly made for routine production inspection and quality assurance tasks where quick, repeatable acceptance checks are required.

How is the thread direction indicated?
The gauge is specified as a right‑hand UNF thread; this is noted in the product label and technical data for correct matching with components.

Can this gauge replace optical or CMM inspection for threads?
The gauge provides a fast go/no‑go check for thread acceptance and is ideal for high‑volume verification; it complements, but does not replace, dimensional analyses from optical systems or CMMs when form and surface detail measurement are required.

What standards does the gauge comply with?
The gauge is manufactured to check threads according to ANSI/ASME B1.1, making it suitable where that standard is the specification reference.
