Nimonic 90 Hex Bolt (Full Thread) – DIN 933 – ASTM F468 Gr N07090

At Ananka Fasteners Pvt Ltd, we engineer, manufacture, and supply premium Nimonic 90 (UNS N07090) Hex Bolt (Full Thread) built for demanding service. Cobalt-bearing age-hardened Ni-Cr alloy with high creep-rupture strength for turbine blades and bolting. This technical datasheet covers the precise dimensional tolerances per DIN 933 and the material requirements dictated by ASTM F468 Gr N07090 and ASTM B637.

A Nimonic 90 Hex Bolt with a full-length thread is commonly specified where clamp length varies or where maximum thread engagement is required. 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 90 Hex Bolt (Full Thread) Specifications

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

2. DIN 933 Hex Bolt (Full Thread) Dimensions

The DIN 933 specification governs the physical geometry of this product. The tolerances below ensure a secure, reliable mate under service loads. DIN 933 covers fully threaded hex bolts (thread runs the full length).

Thread Configuration

Full-length threading is provided along the entire shank. Buyers should confirm the required nominal diameter, thread series, length and thread class against the purchase drawing or applicable standard before ordering.

3. Nimonic 90 Equivalent Grades

The UNS N07090 Hex Bolt (Full Thread) is manufactured from Nimonic 90, a high-nickel alloy. The equivalent designations below assist with cross-referencing this material against European, British and other national standards.

4. ASTM F468 Gr N07090 Material Requirements

This section details the chemical composition limits and minimum mechanical properties governing Nimonic 90 (UNS N07090) fasteners, as dictated by ASTM F468 Gr N07090 (chemistry & mechanicals) and the raw bar/rod standard ASTM B637.

5. Hex Bolt Applications

Our Nimonic 90 hex bolts are specified across the following industries and service conditions, drawing on the material’s core strengths:

• Turbine Components: Blades, rings and high-temperature fasteners.
• Aerospace: Hot-section rotating and static hardware.
• Power Generation: Creep-resistant bolting.
• High-Temperature Springs: Springs retaining load above 700°C.

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 Bolts 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.
