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.

Worked for me

I've ordered from Fair Wind Fasteners twice so far and both times they were accurate and fast in fulfilling the order. That works for me.
