Aluminum Thumb Screw

Our Aluminum Thumb Screws are precision-engineered fasteners designed for easy, tool-free installation and removal. Made from high-grade aluminum alloy, these screws feature a knurled head for superior grip and handling. Each CNC aluminum thumb screw is machined with tight tolerances to ensure consistent quality and performance.
Lightweight, durable, and corrosion-resistant, these anodized aluminum thumb screws are ideal for applications requiring frequent adjustments, such as electronic devices, camera equipment, and mechanical assemblies. We also provide custom aluminum thumb screws in different sizes, colors, and head styles to meet your specific requirements.

Key Features

• High Precision: Manufactured through advanced CNC Machining, ensuring accurate thread fit and dimensional stability.

• Multiple Material Options: Available in aluminum, stainless steel, and carbon steel, meeting both strength and weight requirements.

• Anodized Surface Finish: Provides enhanced corrosion resistance and aesthetic appeal.

• Customizable Design: Support for OEM/ODM customization including head shape, thread size, color, and logo engraving.

• Lightweight & Durable: Ideal for lightweight assemblies without sacrificing strength.

• Tool-Free Operation: Easy hand tightening using the knurled head or hand knob design.

Manufacturing Process

Our aluminum thumb bolts and aluminum hand screws are produced using advanced precision equipment to ensure top performance and consistency:

1. CNC Machining: High-precision CNC aluminum thumb screw production for tight tolerance and smooth surface.

2. Turning & Milling: Achieves uniform thread structure and precise knurled patterns.

3. Heat Treatment: Enhances hardness and mechanical strength when applicable.

4. Surface Finishing: Includes polishing, plating, or anodizing for improved appearance and corrosion protection.

5. Assembly & Inspection: 100% visual and dimensional checks before packaging.

Material Selection

We provide a wide range of materials to meet diverse industrial requirements:

• Aluminum Alloy (6061 / 7075): Lightweight, corrosion-resistant, excellent for anodized aluminum thumb screw applications.

• Stainless Steel (304 / 316): High strength, rust-resistant, suitable for outdoor or marine environments.

• Carbon Steel: Offers superior tensile strength and load capacity, ideal for heavy-duty use.
  Each thumb bolt aluminum alloy or aluminum knurled bolt is carefully selected based on mechanical requirements and environmental conditions.

Surface Treatment Options

Enhance both function and appearance with customized finishes:

• Anodizing (Colorful Options): Black, silver, red, blue, gold, and more.

• Polishing: For smooth, reflective surfaces.

• Electroplating: Nickel, zinc, or chrome plating for extra corrosion resistance.

• Passivation: Strengthens oxidation resistance on stainless steel parts.

• Sandblasting: For matte surface texture and improved grip.
