Floating Docks: Which Screws Should You Use?

Ah, the joys of owning a floating dock! There's nothing quite like spending a sunny day lounging on the water, surrounded by the soothing sounds of nature. But, as any dock owner knows, maintaining your dock can be a real challenge. One of the most important components of your dock are the screws that hold it all together.

Choose the Correct Screws the First Time

We are quick to choose the cheapest, any old screw to construct or repair our docks. After all, screws are just a small part of the overall structure, right? Wrong! The screws you use can make all the difference between a dock that lasts for years to come and one that's constantly in need of repair.

That's because floating docks are exposed to some of the toughest conditions imaginable. They're constantly battered by waves, subjected to extreme temperatures, UV rays, and exposed to corrosive saltwater and marine life. If your screws aren't up to the task, they can quickly become damaged, leading to costly repairs or even complete failure.

The Case for Stainless Steel Screws

So, what type of screws should you use for your floating dock? The answer is simple: stainless steel. But not just any stainless steel screws will do. You'll want to look for screws made from marine-grade stainless steel, specifically 316 grade.

316 grade stainless steel is the gold standard for marine applications. It's incredibly resistant to corrosion, even in saltwater environments. This means that your screws will withstand the constant exposure to water and marine life, ensuring your dock remains safe and secure.

But what about other types of stainless steel? 304 grade, for example, is a popular choice for many applications. However, it's not completely suitable for marine environments. 304 grade stainless steel is perfect for general use and decking but can be corroded by the high levels of salt and moisture found in marine areas.

What About Coated Screws?

Another option you may come across is coated screws. These screws are made from a lower-grade material, such as steel or aluminum, and then coated with a layer of protective material, often zinc or chrome. While coated screws may seem like a cost-effective option, they're not the best choice for floating docks.

That's because the coating can wear off over time, exposing the underlying material to the elements. This can lead to corrosion and damage, even if the coating is still intact. Additionally, coated screws may not be as strong as stainless steel screws, which can compromise the structural integrity of your dock.

316 Grade Stainless Steel Screws: The Only Choice

So, why should you choose 316 grade stainless steel screws for your floating dock? Here are just a few benefits:

• Corrosion resistance: 316 grade stainless steel is incredibly resistant to corrosion, even in harsh marine environments.
• Strength: 316 grade stainless steel screws are incredibly strong, ensuring your dock remains secure and stable.
• Low maintenance: 316 grade stainless steel screws require very little maintenance, as they're resistant to corrosion and damage.
• Long lifespan: 316 grade stainless steel screws can last for decades, even in harsh marine environments.

Final Thoughts

So, we come to it 316 grade stainless steel screws are the best choice for marine environments, offering unparalleled corrosion resistance, strength, and durability. While they may be more expensive than other options, the benefits far outweigh the costs.

So, next time you're building or repairing your floating dock, make sure to choose 316 grade stainless steel screws.

Your dock – and your wallet – will thank you!
