Introduction: Why Custom Aluminum Fasteners Matter in 2025
Custom aluminum threaded fasteners are vital in aerospace, automotive, electronics, and renewable energy. Lightweight and corrosion-resistant, they help companies meet emission and efficiency targets.
According to the International Aluminum Institute (https://www.world-aluminium.org/), aluminum usage in structural and fastener applications grew over 6% in 2024. However, many buyers still struggle with:
- Inconsistent thread quality
- Delayed deliveries
- Unexpected lifecycle costs
This article provides guidance on fastener types, alloy selection, surface treatments like anodizing, and trusted supplier practices.
What Are the Most Common Types of Threaded Aluminum Fasteners?
Choosing the right fastener ensures mechanical stability and production efficiency. The most widely used types include:
- Bolts – external threads, paired with nuts or tapped holes.
- Screws – thread directly into components or create their own threads.
- Studs – double-ended threads for engines and assembly fixtures.
- Threaded Inserts – placed inside softer materials for added strength.
| Type | Description | Use Case |
|---|---|---|
| Bolts | External threads with nuts or tapped holes | Structural assembly |
| Screws | Self-tapping or machine threads | Electronics, frames |
| Studs | Threaded ends for fixed positions | Gearbox housing, engine mounts |
| Inserts/Bushings | Embedded into soft base materials | Plastic housings, composite parts |
Thread compatibility matters—reference standards include UNC, UNF, ISO metric, and JIS (see https://en.wikipedia.org/wiki/Screw_thread).
Choosing the Right Aluminum Grade for Threaded Applications
Thread reliability depends heavily on alloy choice. Strength, machinability, and corrosion resistance vary widely.
| Alloy | Yield Strength | Corrosion Resistance | Machinability | Best Use Case |
|---|---|---|---|---|
| 6061 | \~250 MPa | High | Excellent | General structure, brackets |
| 2024 | \~345 MPa | Moderate | Good | Aerospace structural fasteners |
| 7075 | \~480 MPa | Moderate | Fair | Critical load-bearing components |

The Benefits of Anodizing in Threaded Part Manufacturing
Anodizing enhances performance through a controlled oxide layer, offering:
- Improved Hardness (up to 70 HRC in Type III)
- Corrosion Protection in harsh conditions
- Visual Sorting via color options
- Better Thread Engagement reducing galling
| Type | Thickness | Typical Use |
|---|---|---|
| Type II | 5–25 µm | Decorative, moderate environments |
| Type III | 25+ µm | High-durability, industrial use |
Note: Threads must be properly masked to preserve dimensional tolerance during anodizing.
