These Foil Drive screws are far from your average hardware store screws. They're precision CNC machined from 316 stainless steel. They feature a unique shoulder under the head that perfectly seats into the hub. Plus, threadlocker is already applied to the threaded section.
KEY INFORMATION
Specific M3x30 mm screw set for Foil Drive 3-blade propeller, CNC machined from 316 stainless steel.
What we like
- Shoulder under the head: This design centers the screw in the hub. It prevents shear forces.
- Pre-applied threadlocker: No need to add anything during assembly. Your tightening holds securely.
- 316 stainless steel: This is marine-grade stainless steel, not recycled material.
- Individual CNC machining: Each screw is precisely machined, not mass-produced by stamping.
- It is a consumable: It's always better to break a screw worth a few euros than to damage a hub or a blade.

DETAILED DESCRIPTION
Why a dedicated screw?
A standard M3x30 screw has threads that extend all the way to the head. In a propeller hub, this means the stress is borne by the threads, which are the weakest point. The Foil Drive screw features a smooth, shouldered section under the head that seats firmly in the hub's housing. This design transfers stress through that robust bearing surface, not the threads. This crucial detail significantly reduces the chance of breakages.
Pre-applied threadlocker.
These screws arrive with threadlocker already applied to the threads. You won't need to measure or wait for it to dry. This also prevents the common mistake of using strong threadlocker instead of medium, which can make subsequent disassembly a real pain. Be aware that the product loses effectiveness after several disassemblies. These screws aren't designed to last forever.
What causes them to break?
Any impact on the propeller, whether it's a rock or a piece of floating wood, means the screw takes the full force. That's its job: it acts as a mechanical fuse. Always keep a spare set in your bag. Breakdowns inevitably happen on those perfect days. Foil Drive's website provides guidance on how to minimize breakages, including proper tightening torque.

FAQ
Can I use off-the-shelf screws?
Technically, they'll fit, but they lack the crucial shoulder, meaning the force is transferred through the threads. On a fast-spinning propeller, this is a critical detail. We strongly advise against it.
Do these work with a 2-blade propeller?
No, the 2-blade hub uses a different screw set. This product code is specifically for the 3-blade propeller system.
