Thread Plug Gauge UNC 3/4" x 10 tpi (ANSI/ASME B1.1) — 2B tolerance by Metav IndustryLine

The Thread Plug Gauge UNC 3/4" x 10 tpi (ANSI/ASME B1.1), tolerance 2B is a hardened gauge-steel go/no-go plug designed for rapid verification of UNC internal threads to established American standards.

• Hardened gauge steel construction
• ANSI/ASME B1.1 thread standard
• Tolerance class 2B for internal threads
• 3/4" UNC, 10 tpi thread size

Clear conformity for production control

Made from hardened gauge steel and manufactured to conform with ANSI/ASME B1.1/B1.2, this go/no-go plug enables immediate verification of internal threads using the well‑established 2B tolerance criterion. The plug’s geometry corresponds to the UNC form at 10 tpi, providing a straightforward, tactile pass/fail check that removes ambiguity from thread acceptance. As a consequence, inspection throughput is increased and the rate of rework or scrapped parts is reduced, which contributes directly to production efficiency and measurable cost avoidance.

Designed for the shop-floor and inspection bench

The compact, single-piece construction balances rigidity with ease of handling, so the gauge is suited to both incoming inspection and rapid in-process checks. Its light mass supports quick manoeuvring and repeated use without operator fatigue, while the go/no-go principle offers a deterministic decision path during assembly or quality control. For workshop teams and quality engineers, this translates into consistent, repeatable checks and reduced dependence on subjective assessment — a reliable tool for everyday inspection tasks.

Traceability and standardised quality assurance

Supplied with clear labelling and identifiable marking, the gauge integrates readily into formal inspection routines and traceability records. Conformance to recognised thread standards simplifies documentation and communication across supply chains and inspection reports. When paired with Metav’s quality-filtered distribution, customers benefit from access to a wide range of precision measuring equipment and the assurance that components meet industry expectations for durability and dimensional accuracy.

FAQ

What is the intended use of this plug gauge?
The Thread Plug Gauge UNC 3/4" x 10 tpi (ANSI/ASME B1.1), tolerance 2B is intended for go/no-go verification of UNC internal threads to ensure compliance with the 2B fit class.

Which standard does the gauge conform to?
This plug gauge is manufactured to meet the ANSI/ASME B1.1/B1.2 thread form and pitch specifications for UNC threads.

How does the 2B tolerance class affect acceptance criteria?
Tolerance class 2B defines the internal thread limits; the gauge provides a direct, binary check against those limits to confirm whether a thread falls within acceptable bounds.

Can this gauge be used in production and incoming inspection?
Yes, the robust design and clear pass/fail action of the UNC 3/4" x 10 tpi plug gauge make it suitable for both production-line checks and incoming component inspection.

Is the material suitable for frequent shop-floor use?
Constructed from hardened gauge steel, the plug gauge is built for repeated use and maintains form stability under normal inspection conditions.
