Thread plug gauge UNC 1 1/4" × 7 TPI — hardened gauge steel (ANSI/ASME B1.1)

The thread plug gauge UNC 1 1/4" × 7 TPI (2B) verifies internal UNC threads to ANSI/ASME B1.1 tolerances for consistent production acceptance and incoming inspection.

• Hardened gauge steel construction
• ANSI/ASME B1.1/B1.2 compliant
• Tolerance class 2B for internal threads
• Suitable for repeatable inspection tasks

Ensure production conformity with a standardised UNC check

The thread plug gauge UNC 1 1/4" × 7 TPI (2B) is designed to provide a simple, repeatable pass/fail check for internal UNC threads produced to ANSI/ASME B1.1. Using a purpose-made plug eliminates subjective assessment during assembly or quality control, thereby reducing rework and preventing faulty components from entering the next production stage. The specified 2B tolerance denotes the standard internal-thread fit commonly required in mechanical assemblies, so the gauge supports traceable verification against widely accepted industrial norms.

Robust materials that keep inspection precise over time

Manufactured from hardened gauge steel, the gauge resists wear and preserves the reference form of the thread flanks under repetitive use. That material choice maintains measurement integrity across long inspection runs and lowers lifetime cost by extending service intervals. The compact mass and balanced geometry make handling straightforward during routine checks in the workshop or inspection room, while the clear marking of size and pitch simplifies inventory control and quick identification during process audits.

Integrate a fast go/no-go routine into quality workflows

A thread plug gauge streamlines in-process and incoming inspections by offering immediate go/no-go decisions without specialised metrology equipment. The tool suits machine shops, assembly lines and quality departments where time-efficient verification is crucial; adopting standardised gauges supports consistent results and simplifies operator training. Documented identifiers such as SKU and GTIN ensure each gauge can be recorded in quality logs and inventory systems for traceability and audit purposes.
