Boat Screws & Self-Tapping Screws

Marine Grade Screws for Boat Construction and Repairs

Boat screws, also known as marine screws, are specifically designed to withstand the harsh conditions of marine environments. These screws are made from corrosion-resistant materials such as stainless steel, ensuring durability and strength.

Types of Marine Screws

• Self-Tapping Screws: Marine-grade self-tapping screws are a popular choice in boat construction and repairs. These screws can cut their own threads when driven into materials, making them ideal for securing parts without the need for pre-drilling. They are available in various head styles, including flat head, oval head, pan head, and hex head.
• Marine Grade Wood Screws: Marine wood screws are designed for fastening wooden components of the boat. They come in materials such as silicone bronze and brass, which offer excellent corrosion resistance. Both materials are good for self-tapping wood screws.
• Sheet Metal Screws: These screws are used for securing thin metal sheets, soft plastics, and fiberglass. They often do not require pre-drilling, making them versatile for various applications.

Materials Used in Marine Screws

• Stainless Steel: Offers excellent corrosion resistance, especially grades like 316 stainless steel or even 304, which is ideal for continuous water exposure.
• Silicone Bronze: Perfect for wooden boat construction, providing superior corrosion resistance and compatibility with wood.
• Brass: Another corrosion-resistant material suitable for marine environments.
• Galvanized Steel: Galvanized steel is a cost-effective option with good corrosion resistance due to its zinc coating.

Best Screws for Aluminum Boats

When working with aluminum boats, it is crucial to select screws that prevent galvanic corrosion. Stainless steel marine screws are commonly used, but care must be taken to use a barrier like Tef-Gel to prevent direct contact between dissimilar metals.

Proper Selection and Installation

Choosing the right screw and installing it correctly is important for maintaining the integrity of your boat's structure.

Here are some best practices:

• Pre-Drilling: For materials like hardwood or composites, pre-drilling ensures the screws sit firmly without causing the material to crack.
• Sealant Use: Apply a marine-grade sealer to prevent water intrusion and reduce the risk of corrosion.
• Avoid Mixing Metals: Use screws and materials of the same metal type to prevent galvanic corrosion.

Regular Inspection and Maintenance

Regularly inspect your boat screws for signs of corrosion or loosening. Replace any damaged screws promptly to maintain the structural integrity of your boat.
