Thread plug gauge UNF No. 6 x 40 (2B) – plug gauge, ANSI/ASME compliant, Metav IndustryLine

The Thread plug gauge UNF No. 6 x 40 (2B) is a hardened gauge‑steel mandrel for checking internal UNF No.6‑40 threads to ANSI/ASME B1.1 tolerances, designed for workshop and quality‑control use

• ANSI/ASME B1.1 compliant
• Hardened gauge steel construction
• Tolerance class 2B
• No. 6 x 40 UNF thread

Ensure thread conformity where it matters most

This plug gauge delivers repeatable verification of internal UNF threads in production and inspection environments. By matching the ANSI/ASME B1.1 profile for a No. 6 x 40 UNF thread and holding 2B tolerance, the mandrel reduces ambiguous assessments and supports fast go/no‑go decisions on the shop floor. The direct benefit is fewer reworks and clearer conformity records, enabling more efficient throughput and predictable quality outcomes.

Built for durable workshop performance

Constructed from hardened gauge steel, the gauge withstands routine handling and resists wear that would otherwise compromise fit checks. The right‑hand thread orientation conforms to standard fastener geometry and the compact form aids manoeuvrability when inspecting blind or confined bores. The robust material and finish mean longer service life and less frequent replacement, which translates to lower long‑term tooling costs and steadier inspection intervals.

Fits into established inspection workflows with minimal friction

Intended for machine shops, assembly plants and quality departments, the plug mandrel integrates easily into sampling plans and first‑article inspections. Its concise design simplifies handling during batch checks and its unambiguous acceptance criteria aid traceability in inspection reports. When used alongside documented procedures, the gauge supports consistent inspection results, effective quality control and clear audit trails for compliance purposes.

FAQ

What is the primary purpose of this gauge?
The Thread plug gauge UNF No. 6 x 40 (M315.916.F) is intended to verify the dimensional conformity of internal UNF No.6‑40 threads against ANSI/ASME B1.1 tolerances, ensuring parts meet the specified 2B acceptance criteria.

Which materials is the gauge made from?
The mandrel is manufactured from hardened gauge steel to deliver wear resistance and stable contact geometry during repeated inspections of internal threads.

Is the thread orientation standard?
Yes, the plug mandrel is supplied with a right‑hand thread, corresponding to the conventional fastener direction for UNF No.6‑40 applications.

Can this gauge be used for serial inspection in a production line?
The gauge is suited to routine sampling and first‑article checks; its precise profile and hardened construction make it appropriate for repeated checks within production and quality workflows.

What does tolerance class 2B indicate for inspection?
Tolerance class 2B signifies the standard internal thread tolerance for general engineering applications; using a 2B plug mandrel confirms that the component falls within the common commercial fit for UNF internal threads.
