Thread plug gauge UNF 5/8-18 (ANSI B1.1) — 2B, hardened gauge steel (Metav IndustryLine)

The Thread plug gauge UNF 5/8-18 (ANSI B1.1) 2B is a dedicated inspection tool for verifying internal right‑hand UNF threads to the ANSI/ASME B1.1 standard in production and quality‑control environments

• ANSI/ASME B1.1 compliant thread profile
• Hardened gauge steel construction
• Tolerance class 2B for precision fit
• Right‑hand UNF 5/8‑18 thread form

Assured thread conformity for reliable assemblies

The gauge is manufactured from hardened gauge steel, providing dimensional stability and wear resistance that prolongs service life in regular inspection cycles. Conforming to ANSI/ASME B1.1, the device ensures thread geometry matches the standard UNF profile; this reduces uncertainty in acceptance decisions and lowers the risk of assembly failures. The specified 2B tolerance denotes the intended internal thread fit for general use, balancing manufacturability and functional clearance.

Efficient in‑line inspection with robust design

Designed as a practical plug gauge for shop and workshop use, the item supports quick go/no‑go verification of internal threads, enabling rapid pass/fail decisions during production runs. The UNF 5/8‑18 pitch is widely used in hydraulic and mechanical assemblies; using a standardised gauge minimises rework and keeps throughput steady. The compact, hardened design also resists deformation under normal handling, so calibration intervals remain predictable and downtime is reduced.

Clear specifications to support procurement and traceability

Technical conformity and material specification simplify supplier qualification and internal documentation. The gauge’s construction from hardened gauge steel and adherence to ANSI/ASME norms provide a verifiable basis for quality records and procurement lists, supporting audit trails and end‑user confidence. For shops seeking dependable measuring tools without excessive complexity, this gauge balances precision and usability, making it suitable for both small series and larger production contexts.

FAQ

What standard does this plug gauge follow?
The Thread plug gauge UNF 5/8‑18 (ANSI B1.1) 2B is manufactured to the ANSI/ASME B1.1/B1.2 thread form, ensuring compatibility with parts specified to that standard.

What does tolerance class 2B mean for inspection?
Tolerance class 2B indicates a standard internal thread fit; the gauge confirms that the internal thread meets the dimensional and form criteria expected for general mechanical assemblies.

Is this gauge suitable for hydraulic fittings and similar components?
Yes — the UNF 5/8‑18 form is common in hydraulic and mechanical applications, and the hardened construction makes the gauge appropriate for routine production checks.

How is the gauge intended to be used in practice?
The plug gauge is used for go/no‑go verification of internal threads; a pass confirms conformity to the specified thread form and tolerance class, allowing quick acceptance decisions.
