1. Types of Titanium Fasteners

Titanium fasteners come in multiple forms, each tailored for specific applications:

  1. Bolts and Screws – For structural connections where strength and lightweight are critical.
  2. Nuts and Washers – Provide secure fastening in corrosive or high-temperature environments.
  3. Rivets – Ideal for aerospace and automotive applications where vibration resistance is essential.
  4. Custom Fasteners – CNC-machined or precision-molded to meet unique design specifications.
