What Are Aluminum Fasteners?
Aluminum fasteners are lightweight, durable mechanical components used to join or secure materials in industries ranging from aerospace to construction. Made from aluminum alloys like **6061** and **7075**, these fasteners combine high strength-to-weight ratios, corrosion resistance, and thermal conductivity, making them ideal for applications requiring both performance and efficiency.
1. Bolts & Screws:
Hex bolts: For structural applications.
Self-tapping screws: Designed for aluminum-to-aluminum or mixed-material joints.
High-strength aerospace bolts: Made from 7075-T6 alloy for extreme load-bearing capacity.
2. Nuts & Washers:
Lock nuts: Prevent loosening under vibration.
Flange nuts: Integrated washers for distributed load.
3. Rivets:
Blind rivets: Ideal for hollow structures.
Solid rivets: Used in high-stress environments like aircraft assembly.
Applications of Aluminum Fasteners
✔Aerospace: 7075-T6 rivets for aircraft frames.
✔Automotive: 6061-T6 bolts for lightweight chassis.
✔Construction: Anodized anchors for corrosion-resistant structures.
✔Marine: Saltwater-resistant fasteners for shipbuilding.
