Nickel Alloy Nut

The nut is the most basic fastener used in conjunction with bolts and studs. It transmits loads through thread engagement to achieve reliable connections for equipment. The nickel alloy nuts supplied by Hefei Talan Metal Materials Co., Ltd. are made from high-quality nickel-based alloy bars or hexagonal bars. They are processed through multiple precise procedures such as cold heading/ hot forging, tapping, solution heat treatment, and surface treatment. They feature high thread accuracy, excellent mechanical properties, outstanding corrosion resistance, and good dimensional consistency. They are specifically designed for critical connections in demanding conditions such as marine engineering, petrochemicals, nuclear energy, etc.

Nut Types:

1. Hex Nut: Most common, suitable for general connections
2. Hex Thin Nut: For space-constrained applications
3. Hex Thick Nut: For applications requiring longer thread engagement
4. Cap Nut: For applications requiring closed thread ends
5. Flange Nut: Integrated washer face, increased bearing area
6. Lock Nut: Nylon insert lock or all-metal lock, for anti-loosening
7. Wing Nut: For manual assembly/disassembly applications
8. Round Nut: For special applications such as bearing retention

Supply Range

Nominal Diameter (d): M3 – M100 (1/8 inch – 4 inches); Larger sizes negotiable

Thread Specification: Coarse Thread, Fine Thread, Metric Thread

Thread Accuracy: 6H (common for internal threads), 4H/5H/6H precision grades available

Surface Condition: Pickled, Passivated, Polished optional

Multiple Locking Types Available

Various locking nuts available according to anti-loosening requirements:

1. Nylon Insert Lock Nuts: Nylon insert embedded in nut top, creating locking force through friction with bolt threads, reusable multiple times
2. All-Metal Lock Nuts: Locking force created through non-circular deformation at nut top, suitable for high-temperature applications
3. Flange Lock Nuts: Locking teeth under flange face,嵌入 contact surface to prevent loosening

Strict Mechanical Property Testing

1. Proof Load Testing: Verifying nut load capacity
2. Hardness Testing: Ensuring hardness uniformity

Multiple Surface Treatments Available

1. Various surface treatments available according to application environment:
2. Passivation: Enhancing corrosion resistance
3. Pickling: Removing scale, clean surface
4. Polishing: Improving surface finish
