What makes our wood screws the best?


Full Body: Our bronze wood screws have a shank diameter that is the same size as the outside of the threads. That means your clearance hole will be completely filled, creating a waterproof seal. Full bodied screws are made from a larger wire stock than screws that aren't full bodied, meaning they are stronger when they hold and stronger when you are driving them in.

Cut Threads: The threads are cut, not rolled. Rolled threads have a reduced shank size, and but ours have a full sized shank and sharper threads. Most other companies produce rolled thread screws and you'll find they twist and break when driving them in, and can leave a compromised fastener in your project without even knowing it.

Cold Pressed Heads: The heads on these screws are cold formed, which hardens them through a process called "work hardening". Experience less stripped screw heads with our cold pressed heads.

Guaranteed 651 Silicon Bronze Alloy: We guarantee that you'll get the correct alloy when you order through us. 651 Silicon Bronze is the ideal alloy for bronze screws in your traditional boat building project, therefore it's the only alloy we will supply our wood screws in. The others may be cheaper, but they're likely not the silicon bronze alloy they claim to be.

Traditional boatbuilders know that there is a glut of imposter alloys and bargain bronze wood screws out there on the market, but Fair Wind Fasteners only supplies Silicon Bronze wood screws of the highest marine grade.

Service above the norm!

After looking at # 20 bronze screws on several websites, I placed an order with Fairwind to complete the rehab of a WW1 destroyer port hole. Immediately after having given all my information and the order confirmed, I realized I came up
short on some needed cotter pins. I was happy to find a phone number and called Rob, he said he had my order right in front of him and he would add the cotter pins, no charge to the same order! Everything arrived as described,promptly and in quality packing to prevent scratching. Thanks Rob!

Great company

Always helpful, fast shipping, great product!
