Marine Grade Nuts and Fasteners for Boats


Marine-grade nuts and fasteners are essential components in boat construction and maintenance, ensuring durability and reliability in the maritime environment.

Materials Used:

  • Stainless Steel: Known for its excellent corrosion resistance and strength. Grades 304 and 316 stainless steel are commonly used, with 316 offering superior resistance due to its molybdenum content.
  • Brass and Silicone Bronze: These materials are also highly resistant to corrosion and are often used in specific marine applications.
  • Titanium: Known for its exceptional strength-to-weight ratio, it is ideal for applications where weight reduction is critical, such as in the boating industry. They also offer excellent corrosion resistance.

Types of Marine Grade Nuts and Bolts

Fisheries Supply offers a comprehensive range of marine nuts, ensuring you have the right fasteners for every application on your boat.

Here are some of the types available:
  • Hex Nuts: Standard boat nuts used in conjunction with bolts.
  • Lock Nuts: These boat nuts feature a nylon insert that prevents them from loosening due to vibrations.
  • Wing Nuts: Designed for easy hand-tightening and removal.
  • Cap Nuts: Also known as acorn nuts, these provide a finished look and protect the bolt threads.
