The fastening and opening of bolts and nuts adopts non-standard design, and the matching
non-standard tools are used to solve the opening and fastening problems. In general, other
wrenches cannot be inserted. In the appearance design of nuts and bolts, non-standard slotting,
opening or pentagonal, heptagonal, nine-corner or custom-made corresponding groove tools
have played a very good anti-theft effect

An Aluminum nuts purple oxide is a type of fastener that has undergone a specialized surface treatment to achieve a decorative and corrosion-resistant purple finish. Here’s a detailed description:
1. Material
-
Made from aluminum (typically grades like 6061 or 7075 for a balance of strength and lightweight properties).
2. Purple Oxidation Process
-
The nut undergoes anodizing, an electrochemical process that thickens the natural oxide layer on aluminum.
-
The purple color is achieved through dye infusion during the anodizing process, where the porous oxide layer absorbs a purple dye before sealing.
-
Alternatively, electrolytic coloring (using metallic salts) can produce iridescent or darker purple hues.
3. Features & Benefits
-
耐食性 – The anodized layer protects against rust and environmental damage.
-
Aesthetic Appeal – Provides a vibrant, consistent purple finish for decorative or color-coding purposes.
-
耐久性 – Harder surface than raw aluminum, improving wear resistance.
-
Electrical Insulation – Anodized aluminum is non-conductive.
4. Common Applications
-
Aerospace & automotive (lightweight, corrosion-resistant fasteners).
-
Electronics & machinery (color-coded components).
-
Aluminum nuts purple oxide
-
Marine & outdoor equipment (enhanced weather resistance).
5. Variations
-
Bright Purple – Vivid, dye-based anodizing.
-
Iridescent Purple – Created via interference effects in hard anodizing.
-
Matte or Gloss Finish – Depending on pre-treatment (e.g., bead blasting for matte).
6. Limitations
-
Not as strong as steel nuts for high-torque applications.
-
The color may fade under prolonged UV exposure unless specially sealed.
