Aluminum hex nuts are light weight while offering excellent corrosion resistance. They have the best strength to weight ratio when compared to nuts of other materials.

A naturally soft material, aluminum can be hardened and is suitable for the aerospace and aircraft industries.

China Aluminum Screws, Inc. offers aluminum hex nuts in various grades, materials and styles. We also carry standard (inch) and metric sizes and supply domestic and import products.

Aluminum options:

  • 2024-T
  • 6061-T6
  • 7075-T6

Whether you need a standard or custom size, China Aluminum Screws has a solution for you. Contact us today by email to inquiry.custom@shapedparts.com or filling out our contact form.
