Do You Know About Marine Grade Fasteners?


Fasteners that were specifically created for the marine industry are referred to as marine-grade fasteners. They are completely resistant to weather and rust in other words. Metals have a difficult time in a saltwater environment, as a result of corrosion.

Any boat, ship, or oil rig’s hull or structure has different “zones” and requires different corrosion-resisting techniques depending on which piece is above water and in operation.

The corrosive nature of saltwater conditions is too much for the majority of stainless-steel fasteners to handle.

To fulfill the objective, it needs certain grades of SS like

  • Duplex stainless steel
  • 316 Grade A4
  • Monel
  • Titanium

Fair Wind Fasteners can supply you with all kinds of marine-grade fasteners needed by you. They have a carefully curated stock of following fasteners of the quality that you can use in your boat


  • Nuts
  • Wood screws
  • Carriage bolts
  • Bolts
  • Machine screws
  • Lag bolts
  • Hex bolts
  • Nails
  • Washers
  • Wood plugs

Because it gives the components a long life, stainless-steel grade AISI 316 A4 is currently used in a growing variety of applications.

It is also referred to as food-grade stainless steel and is extremely beneficial to the chemical, pharmaceutical, and food processing sectors.

Due to its outstanding corrosion resistance, AISI-316 Stainless Steel is ideal for both internal and external applications.

Due to its longevity and resistance to corrosion, this top-grade steel can be more cost-efficient over a long time when compared to A2 Stainless Steel fasteners, which can result in lower maintenance costs, fewer replacement parts, and also less downtime because of breakdown. In addition, it will continue to be clear and bright when exposed to air.

What is a fastener?

The main purpose of a fastener is to clamp two components together, yet the name “fastener” can mean all of the following. Each kind of fastener has a distinctive shape, typically comes in a variety of sizes, and has a distinct name.

Some names are obvious, such as

  • Flat washer
  • Hex nut
  • Hex head bolt
  • Flat head wood screw.

Others have names that are based on a bygone era and are difficult for us to understand in the present era, such as –

  • Escutcheon pins
  • Castle nuts
  • Carriage bolts

Cheese head screws Sizing standards are a little clearer and more in line with the present day. The majority of sizes are either identified by a number or by their actual size.

Knowing what you will be looking for by name will simplify your search for what you need by eliminating a large chunk of the fastener aisle.

The best stainless-steel grade of

Three varieties of stainless steel are frequently used for fasteners.

  • 18-8
  • 304
  • 316

The simplest way to think about it is to keep in mind that corrosion resistance increases with the type number. 316 stainless sheets of steel have better corrosion resistance than 304 stainless steel, while 18-8 stainless steel gives less corrosion resistance.

While corrosion resistance is frequently the goal for boaters, this added protection comes at a price: strength. Each variety of stainless steel has a different tensile strength due to the alloy makeup.
