No. 8 x 36 UNF Thread Plug Gauge, Right-Hand, ANSI/ASME B1.1 2B - Metav IndustryLine

Reliable thread inspection is achieved through the combination of hardened gauge steel, conformity to ANSI/ASME B1.1, and a 2B tolerance for internal threads; this ensures consistent acceptance testing with minimal rework. Order the plug gauge directly via Metav Werkzeuge or consult our specialists for application-specific recommendations.

Thread plug gauge UNF No. 8 x 36 (ANSI/ASME B1.1) — 2B, hardened gauge steel

The Thread plug gauge UNF No. 8 x 36 is a right-hand, hardened gauge designed to check internal UNF threads to ANSI/ASME B1.1 standards for production and quality inspection.

• UNF No.8 x 36 right-hand thread
• Hardened gauge steel construction
• ANSI/ASME B1.1 compliance
• Tolerance class 2B for internal threads

Durable construction for repeatable acceptance checks

Manufactured from hardened gauge steel, the gauge provides wear resistance and dimensional stability for routine inspection tasks. The construction resists abrasion over repeated use, which preserves the thread form and helps avoid false rejections. Compliance with ANSI/ASME B1.1 means the geometry corresponds to the Unified Inch fine thread series; the result is a clear, verifiable basis for acceptance testing that supports consistent production quality and reduces scrap rates.

Clear specification and practical inspection benefits

The specification UNF No. 8 x 36 indicates a Unified National Fine thread with 36 threads per inch; the tool is a right-hand plug intended for internal-thread verification. As a plug gauge, it is used to assess whether an internal thread falls within the 2B tolerance (standard internal tolerance class), providing a go/no-go decision during in-process or final inspection. This straightforward method speeds up quality-control routines and integrates easily into shop-floor workflows where repeatability and speed are priorities.

Traceability, handling and suitability for workshop use

The gauge is supplied in the series identified by SKU M315.917.F and is compact at approximately 0.1 kg, making it simple to handle at the inspection bench. The material and standard information ensure compatibility with common inspection protocols in mechanical engineering and small-part production. For purchasers seeking a reliable standard gauge, the combination of hardened gauge steel and recognised ANSI/ASME tolerancing offers an efficient route to compliance and reproducible results on the production line.

FAQ

What is the purpose of this gauge?
The gauge is intended to verify internal UNF threads and ensure they conform to the 2B acceptance class for the UNF No. 8 x 36 specification.

Which standard does this tool follow?
This plug gauge is manufactured to ANSI/ASME B1.1/B1.2, the standard that defines Unified Inch thread forms and dimensions.

Is the material suitable for repeated use?
Yes—the gauge is made from hardened gauge steel, chosen for wear resistance and dimensional stability under repeated inspection cycles.

How is the tolerance class described?
The tolerance class 2B denotes the standard internal-thread tolerance; the gauge is intended to check acceptance to that class.
