Thread plug gauge UNEF 9/16 x 24 (2B) – hardened gauge steel, right-hand thread

The Thread plug gauge UNEF 9/16 x 24 (2B) is a hardened pass gauge designed for quick verification of internal thread conformity to ANSI/ASME B1.1 in production and inspection environments.

• Precision 2B thread tolerance
• ANSI/ASME B1.1 compatible standard
• Hardened gauge steel construction
• Right-hand thread for standard fittings

Fast, reliable verification of internal threads

The pass gauge serves as a compact acceptance tool for internal threads, reducing measurement time during routine checks. Thanks to the 2B tolerance and the compatibility with ANSI/ASME B1.1, the gauge delivers an immediate Go/No‑Go decision that prevents non-conforming parts from progressing through production. This straightforward verification cuts rework and supports consistent output quality, which is particularly valuable in repetitive manufacturing and assembly processes where cycle time and traceability matter.

Built to resist wear and sustain accuracy

Manufactured from hardened gauge steel, the gauge maintains dimensional integrity across many inspections, giving a durable reference surface that resists deformation. The robust material choice ensures stable contact geometry and extended life when used as intended, lowering lifetime cost compared with softer checking tools. With a clearly defined right-hand thread form and a standard pitch of 24 tpi, the gauge is suited for frequent shop-floor use and keeps inspection programmes predictable and repeatable.

Seamless integration into production control

As a standardised pass gauge, the tool fits easily into existing inspection routines and documentation workflows. The simple Go/No‑Go outcome supports rapid quality decisions at first article inspection or in-process sampling, strengthening process control. The gauge’s adherence to recognised standards facilitates communication between suppliers and quality departments and helps maintain clear acceptance criteria when handing over components.

Practical handling for routine use

Compact and lightweight, the gauge is straightforward to store and to incorporate into inspection kits; it is ready where and when checks are required. The combination of a defined 2B tolerance and hardened construction gives confidence during frequent handling, while the familiar thread form ensures compatibility with standard threaded components. For workshops that require dependable, low-complexity inspection aids, this plug gauge offers a pragmatic balance of precision and durability.

FAQ

What standard does this plug gauge check against?
The plug gauge checks internal threads to ANSI/ASME B1.1/B1.2 specifications and is manufactured to the corresponding form and pitch for reliable conformity tests.

Is the gauge suitable for production line sampling?
Yes, the hardened construction and 2B tolerance make this plug gauge appropriate for frequent in-process checks and rapid Go/No‑Go decisions on the production floor.

Which material is the gauge made from and what does that mean for durability?
Constructed from hardened gauge steel, the gauge delivers wear resistance and long-term dimensional stability under normal inspection use.

Can this gauge be used for both left- and right-hand threads?
This specific item is a right-hand thread plug gauge for UNEF 9/16 x 24; left-hand threads require a corresponding left-hand gauge.

How is traceability handled for this gauge?
The gauge is supplied with product identification (GTIN and article number) so it can be documented in quality records; further calibration traceability can be arranged if required.
