Fasteners can be manufactured using a variety of materials, depending on the specific application requirements. Here are some commonly used materials for molding and machining fasteners:

  1. Steel: Steel is one of the most common materials for fasteners due to its strength and durability. It comes in various grades and finishes, such as stainless steel, carbon steel, and alloy steel, each offering different levels of corrosion resistance and strength.
  2. Aluminum: Aluminum fasteners are lightweight and corrosion-resistant, making them suitable for applications where weight reduction is desired or where exposure to moisture is a concern.
  3. Brass: Brass fasteners are known for their corrosion resistance and attractive appearance. They are often used in decorative applications and in environments where exposure to moisture or chemicals is a consideration.
  4. Titanium: Titanium fasteners are lightweight, highly corrosion-resistant, and have excellent strength-to-weight ratio. They are commonly used in industries such as aerospace, marine, and medical, where high strength and corrosion resistance are required.
  5. Plastics: Plastics such as nylon, polyethylene, or polypropylene are frequently used for molded fasteners due to their low cost, lightweight nature, corrosion resistance, and electrical insulating properties.
  6. Stainless Steel: Stainless steel fasteners are highly resistant to corrosion and come in various grades such as 304, 316, and 18-8. They are commonly used in applications where corrosion resistance is critical, such as marine environments or food processing.

These are just a few examples of the materials used for manufacturing fasteners. The material choice depends on factors such as strength requirements, environmental conditions, cost considerations, and specific application needs.
