Emuge L0100100.5054 Plug Thread Gage 1-1/4-12 2B

Product Description

The EMUGE L0100100.5054 is a double-end plug thread gage used to inspect 1-1/4-12 UNF internal threads to a 2B tolerance class. It provides both a Go member and a No Go member in a single tool, allowing technicians to confirm that a threaded hole falls within the acceptable dimensional range without requiring two separate gages. Manufactured from tool steel with a bright, uncoated finish, the gage meets ASME B1.2 standards and ships with a short-form certification. A handle is included. This type of gage is a standard quality-control instrument used in machining, manufacturing, and assembly environments.

Double-end plug thread gages in this configuration are suited for inspection of tapped holes in production or repair settings. The 1-1/4-12 thread designation covers unified fine-pitch internal threads commonly found in industrial fastener and fluid-fitting applications. The 2B classification represents the standard tolerance class for general-purpose unified internal threads. This gage is appropriate for use by machinists, quality inspectors, and maintenance technicians who need to verify thread conformance to ASME B1.2 requirements before assembly.

Key Features

• Double-end design combines Go and No Go members in one tool
• Inspects 1-1/4-12 UNF internal threads to 2B tolerance class
• Manufactured from tool steel for dimensional stability and wear resistance
• Meets ASME B1.2 thread gage standards
• Includes handle and short-form certification
• Bright, uncoated finish for clear surface inspection and measurement traceability

Compatibility

Designed for inspection of 1-1/4-12 class 2B unified fine-pitch internal threads in accordance with ASME B1.2.

Installation Notes

Plug thread gages are used by quality control inspectors and machinists and require no installation. Before use, clean the threaded hole and the gage members to remove chips, oil, or debris that could affect readings. The Go member should pass through the full thread length with hand pressure only; the No Go member must not enter more than two turns. Store the gage in its case when not in use to protect the precision ground surfaces from damage.
