There is a massive risk of corrosion when screws are exposed to water or moisture on a regular basis. This is why the screws used for any marine applications need to be marine grade stainless steel screws. There are indeed many different types of marine grade stainless steel screws and fasteners available on the market, but they all have one thing in common. They have all been designed especially to be used in or near water – saltwater, to be specific – and are durable and resistant to corrosion.
Below, we take a look at some of the best-known types of marine grade stainless steel fasteners and their uses.
- Marine Grade Stainless Steel Deck Screws
These marine screws have been created for decking that has been placed near the ocean. Like all other marine grade stainless steel screws, these are unlikely to rust. There are a number of different types of marine screws for decking, including Torx bugle head deck screws and trim head deck screws.
- Marine Grade Stainless Steel Machine Screws
These marine screws are often quite small in size and are usually available in pan and flat head varieties. They are most frequently used in machinery or drawer sliders that are going to be used near saltwater.
- Marine Grade Stainless Steel Socket Cap Screws
Socket cap marine screws come in button head and flat head varieties and are designed to be driven by an Allen key. They can be used for multiple saltwater applications and promise higher than normal corrosion resistance.
- Marine Grade Stainless Steel Triple Groove Security Nuts
These are marine fasteners that are often used on boats, docks, piers, and in pools. They are also tamper-proof and resistant to gripping devices. They are available in various heights and diameters depending on the chosen application.
