Thread Plug Gauge UNEF 1/4-32 (2B) — hardened gauge steel, ANSI/ASME B1.1 compliant

The Thread Plug Gauge UNEF 1/4-32 (2B) provides a fast, standardised method for verifying internal UNEF threads to ANSI/ASME B1.1 in workshop and production settings.

• Hardened gauge steel construction
• Conforms to ANSI/ASME B1.1 / B1.2 standards
• Right-hand thread for standard assemblies
• Tolerance class 2B for internal threads

Speedy, standards-based thread inspection for production

The gauge is engineered for immediate verification of internal threads in production and assembly processes. By matching ANSI/ASME B1.1 tolerances and the 2B tolerance class, the tool enables concise go/no-go decisions that reduce rework and keep throughput steady. The UNEF 1/4-32 form with 32 tpi is presented in a compact format that fits inspection benches and handheld checks, supporting fast in-process control without complex measurement setups. This rational approach lowers cycle times and helps maintain consistent quality across batches.

Robust material and geometry for repeatable results

Manufactured from hardened gauge steel, the plug delivers durability under frequent use while protecting the critical thread form against wear. The right-hand thread geometry aligns with common assembly practices, so repetitive checks remain representative of actual mating conditions. Thanks to its solid construction, the inspection tool provides repeatable feedback on thread condition and machining accuracy, helping to identify tool wear or process drift early and to preserve dimensional integrity in series production.

Practical integration into workshop quality routines

As an inspection gauge for internal threads, the instrument complements visual checks and thread measurement systems, acting as a reliable reference in the workshop. The compact design and clear specification make the gauge suitable for assembly control, incoming inspection and final checks prior to dispatch. For technical planning, the tool’s traceable identifiers (SKU and GTIN available) enable straightforward inventory and quality documentation. For any clarification on application or compatibility with specific assemblies, Metav’s sales engineers can advise on selection and process integration.

FAQ

Which standard is the gauge manufactured to?
The Thread Plug Gauge UNEF 1/4-32 (2B) is produced to meet ANSI/ASME B1.1 / B1.2 thread specifications for UNEF forms.

Is this gauge suitable for routine shop‑floor checks?
Yes, the hardened construction and compact form make the plug gauge suitable for routine production and assembly checks where repeatable verification of internal threads is required.

What does the tolerance class 2B indicate?
Tolerance class 2B designates the standard internal thread tolerance for a normal fit according to ANSI/ASME, appropriate for most general engineering and assembly tasks.

How is the thread handedness specified?
This inspection tool uses a right-hand thread, the common direction for standard fastened assemblies.
