Types of Stainless Steel Marine Fasteners

Last Updated on July 1, 2020 by Marsh Fasteners

We often get asked about marine grade fasteners – it makes sense that it would be a common request here in Jupiter! Since these grades of fasteners are common features of our FAQs, we thought we would dedicate this blog not only to explaining what stainless steel marine fasteners are, but to also look at the various types that are available.

What Are Marine Grade Fasteners

Put simply, marine grade fasteners are any type of fastener made to be used in the marine industry. In order to be suitable for these uses, they need to be powerfully resistant to water and corrosion.

The stainless steel that is used to make marine grade fasteners is a particular mix that has molybdenum added into it. This is called 316 stainless steel. The presence of molybdenum enables the steel to both withstand rust and to hold up for years in saltwater. Any screw that is going to be submerged in the water for an extended period of time should be made with at least 6% molybdenum in the alloy.

So, when choosing fasteners for any job involving marine environments, such as repairs on your boat, for example, always make sure you use marine grade stainless steel and not regular grades of the material.

What Types of Marine Grade Fasteners Are There?

There is really no limit in this regard. Whatever fastener you would get in other metals, you can get in marine grade stainless steel – and Marsh Fasteners stocks all of them. This means everything from nuts and bolts to nails, deck screws, washers, sockets, rivets, and pins.
