Thread plug gauge UNF No. 1 × 72, ANSI B1.1 / 2B — Metav IndustryLine

The Thread plug gauge UNF No. 1 × 72, ANSI B1.1 / 2B is a hardened gauge steel mandrel for acceptance testing of UNF internal threads to 2B tolerance, intended for production and workshop quality control.

UNF No.1 × 72 thread form
ANSI/ASME B1.1 compliant
Hardened gauge steel construction
2B tolerance class for internal threads

Fast, reliable go/no‑go inspection for production

A compact plug gauge engineered for unambiguous acceptance testing reduces decision time during inspection. Conforming to ANSI/ASME B1.1 and specified as No. 1, 72 TPI, the mandrel provides a clear go/no‑go result for internal UNF threads; the 2B tolerance designates the standard internal thread acceptance band, simplifying pass/fail criteria for shop‑floor operators. This focused functionality supports higher throughput and fewer ambiguous measurements.

Durable construction that keeps routine checks consistent

Manufactured from hardened gauge steel, the inspection mandrel withstands repeated use with minimal wear, which preserves dimensional fidelity over many cycles. The right‑hand thread form matches common production orientations, and the instrument’s low mass (0.1 kg) eases handling during rapid checks. Together these attributes reduce measurement uncertainty and maintenance intervals, contributing to stable process control.

Standards compliance and practical benefits for quality assurance

The gauge’s compliance with established standards and clear tolerance class offers traceability and confidence in audit situations. As a precision inspection tool it supports documented quality routines and quick verification of threaded components, helping to lower scrap rates and rework. For operations looking to standardise inspection procedures, this mandrel integrates easily into existing control plans and fixture arrangements.

FAQ

What is the primary use of this plug gauge?
The Thread plug gauge UNF No. 1 × 72, ANSI B1.1 / 2B (SKU M315.911.F) is used to perform go/no‑go acceptance checks on UNF internal threads to ensure parts meet the 2B internal tolerance specification.

Which standards does the gauge follow?
The mandrel is manufactured to meet ANSI/ASME B1.1 requirements for UNF thread form and references B1.2 where applicable for gauging practice, ensuring compatibility with common engineering specifications.

Does the gauge check left‑ or right‑hand threads?
This inspection mandrel is supplied with a right‑hand thread form, as specified in the product data, and is intended for matching right‑hand UNF internal threads.

How is the tolerance class interpreted for inspection?
The 2B tolerance indicates the standard internal thread acceptance band; a go/no‑go assessment against this class denotes whether the internal thread is within permitted limits for fit and function.

Is the mandrel suitable for repetitive production checks?
Yes; the hardened gauge steel construction and compact design make the plug gauge suitable for repetitive go/no‑go checks in production and workshop environments, preserving dimensional stability over many cycles.
