Metal Nut

Our metal nuts are engineered for high strength, durability, and precision fit. As a custom precision metal nut manufacturer, we specialize in producing a wide range of threaded metal nuts, CNC machined metal nuts, and forged metal nuts that meet the strictest performance standards. Each metal fastener nut is produced with advanced CNC Machining and inspection technology to ensure superior dimensional accuracy and consistent thread engagement.

We provide full customization options—whether you need a custom metal nut with special threads, surface treatment, or non-standard dimensions, our experienced engineers can meet your specific fastening requirements.

Key Features

• High Precision: Manufactured using CNC Machining, turning, and milling to achieve tight tolerances.

• Material Versatility: Available in carbon steel, stainless steel, aluminum alloy, brass, titanium, and other metals.

• Customizable Solutions: OEM and ODM supported; special sizes, shapes, and threads can be tailored.

• Excellent Strength & Durability: Designed for demanding industrial, automotive, and aerospace environments.

• Comprehensive Surface Treatments: Options for corrosion resistance, appearance, and enhanced performance.

• Reliable Quality: 100% inspection before shipment to ensure consistent quality for every metal hex nut or metal lock nut.

Manufacturing Process

1. Material Selection & Cutting – Selecting premium-grade metal bars or rods.

2. CNC Machining – Multi-axis CNC machined metal nut production ensures precision threads and perfect concentricity.

3. Turning & Milling – Fine shaping and chamfering for smooth assembly.

4. Forging (Optional) – For forged metal nuts, hot or cold forging improves mechanical strength and grain structure.

5. Heat Treatment – Enhances hardness, tensile strength, and wear resistance.

6. Surface Finishing – Polishing, plating, or anodizing to achieve corrosion resistance and visual appeal.

7. Inspection & Quality Control – Dimensional checks, surface roughness tests, and thread gauge inspections ensure every product meets specifications.

Material Selection

• Carbon Steel: High strength and cost-effective, suitable for general mechanical applications.

• Stainless Steel (304, 316): Excellent corrosion resistance for marine and outdoor use.

• Aluminum Alloy: Lightweight, corrosion-resistant, and ideal for aerospace and electronics industries.

• Brass: Offers good electrical conductivity and corrosion resistance.

• Titanium: Ultra-lightweight with exceptional strength-to-weight ratio for high-end applications.

Surface Treatment Options

• Polishing – Smooth surface and refined appearance.

• Zinc / Nickel / Chrome Plating – Improved corrosion resistance and durability.

• Anodizing (for aluminum) – Enhanced oxidation protection and color options.

• Black Oxide – Added rust resistance with a matte finish.

• Passivation – Removes impurities and strengthens anti-corrosion performance.

Precision & Quality Control

We adopt strict inspection standards to ensure every precision metal nut meets ISO and DIN standards.

• Tolerance: ±0.01 mm

• Surface Roughness: Ra ≤ 0.8 μm

• Inspection Tools: CMM (Coordinate Measuring Machine), Thread Gauges, Calipers, and Hardness Testers.
  Each custom precision metal nut is thoroughly inspected from raw material to final packaging, ensuring stable quality and long-term reliability.
