Aluminum nuts blue oxide

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

Aluminum Nut with Blue Oxide Coating – Description

Aluminum nuts with a blue oxide coating are lightweight, corrosion-resistant fasteners designed for applications where weight savings and aesthetic appeal are important. The blue oxide finish provides a decorative and mildly protective layer while maintaining the nut’s conductivity and non-magnetic properties.

主な特徴

1. 素材：

   • Made from aluminum alloys (typically 6061-T6 or 7075-T6 for higher strength).

   • Lightweight (~1/3 the weight of steel) with good corrosion resistance.

2. Blue Oxide Coating:

   • A chemical conversion coating (not anodized) that provides:

     • Mild corrosion resistance (less than anodizing but better than bare aluminum).

     • Decorative blue-black finish (for aesthetic or color-coding purposes).

     • Non-conductive interference (unlike anodizing, which can affect conductivity).

   • Thinner than anodizing, so it doesn’t significantly alter thread dimensions.

3. Locking Mechanism (If Applicable):

   • Some blue oxide aluminum nuts may include:

     • Nylon insert (Nyloc) for vibration resistance.

     • Serrated flange for better grip.

     • Prevailing torque design (all-metal locking).

4. 利点がある：

   • Lightweight – Ideal for aerospace, automotive, and cycling applications.

   • Non-magnetic & Conductive – Used in electronics and RF applications.

   • Aesthetic appeal – Often used in custom builds, motorcycles, and drones.

   • Moderate corrosion resistance – Suitable for indoor or mild outdoor use.

5. Limitations:

   • Not as corrosion-resistant as anodized or stainless steel nuts.

   • Lower strength compared to steel or titanium.

   • Blue oxide can wear off over time with friction.

一般的な用途：

• Aerospace & drones (weight-sensitive assemblies).

• Custom automotive & motorcycles (decorative fasteners).

• Electronics & electrical enclosures (non-magnetic, conductive properties).

• Bicycles & sporting equipment (lightweight components).

Conclusion:

Blue oxide aluminum nuts are a good choice for lightweight, non-magnetic applications where moderate corrosion resistance and an attractive finish are desired. However, for harsher environments, anodized or stainless steel nuts may be more suitable.
