Nimonic 75 Hex Nut – ASME B18.2.2 – ASTM F467 Gr N06075

At Ananka Fasteners Pvt Ltd, we engineer, manufacture, and supply premium Nimonic 75 (UNS N06075) Hex Nut built for demanding service. Solution-treated Ni-Cr alloy with good oxidation resistance and moderate strength for sheet and bar to 950°C. This technical datasheet covers the precise dimensional tolerances per ASME B18.2.2 and the material requirements dictated by ASTM F467 Gr N06075 and ASTM B637.

A Nimonic 75 Hex Nut is the standard mating nut for general-purpose bolted assemblies and is manufactured to match the thread series of its corresponding bolt. The tables below provide the principal dimensions, equivalent material grades, chemical composition and mechanical properties covered by the technical data for this product.

1. Nimonic 75 Hex Nut Specifications

Our hex nuts are manufactured in standard and custom configurations, ensuring a precise fit for demanding structural, piping, and chemical-process applications.

2. ASME B18.2.2 Hex Nut Dimensions

The ASME B18.2.2 specification governs the physical geometry of this product. The tolerances below ensure a secure, reliable mate under service loads.

Thread Configuration

The nut thread is manufactured to match the corresponding bolt thread series and class. Buyers should confirm the required nominal size, thread series and thread class against the purchase drawing or applicable standard before ordering.

3. Nimonic 75 Equivalent Grades

The UNS N06075 Hex Nut is manufactured from Nimonic 75, a high-nickel alloy. The equivalent designations below assist with cross-referencing this material against European, British and other national standards.

4. ASTM F467 Gr N06075 Material Requirements

This section details the chemical composition limits and minimum mechanical properties governing Nimonic 75 (UNS N06075) fasteners, as dictated by ASTM F467 Gr N06075 (chemistry & mechanicals) and the raw bar/rod standard ASTM B637.

5. Hex Nut Applications

Our Nimonic 75 hex nuts are specified across the following industries and service conditions, drawing on the material’s core strengths:

• Heat Treatment: Furnace hardware and thermocouple sheaths.
• Aerospace: Ring sections and honeycomb structures.
• Gas Turbines: Combustion-zone components.
• Industrial Furnaces: Trays, baskets and fixtures.

For severe sour, high-temperature or highly acidic service, the exact operating conditions should be reviewed against the alloy’s certified data rather than general nickel-alloy assumptions.

6. Manufacturing, Inspection and Quality Assurance

Every batch of Hex Nuts produced undergoes rigorous internal and third-party testing to ensure zero-defect delivery. We supply complete traceability with our global shipments.

• Material Test Certificates (MTC): Provided strictly as per EN 10204 3.1 / EN 10204 3.2.
• Non-Destructive Testing (NDT): Positive Material Identification (PMI), Visual Inspection, Dimensional Checks, and Micro/Macro testing.
• Destructive Testing: Tensile tests, hardness testing, chemical analysis, and (where applicable) intergranular corrosion (IGC) tests.
