Common Questions

How do I know if I need the M4 or M5 size?
The screw fits surfboard fin boxes that are threaded for M4 or M5 bolts. Check your fin or fin box specifications. If not sure, measure the existing screw’s diameter: M4 is 4 mm, M5 is 5 mm.
What material is the screw made of?
The screw is made of 316 stainless steel, which is highly corrosion-resistant and suitable for saltwater use.
Does the price include more than one screw?
No, the price is for a single screw. You order one unit per the size selected (M4 or M5).
Is this screw compatible with all surfboard fins?
It is designed for standard single fin systems that use a hand-tightened bolt. It will fit fin boxes with M4 or M5 threaded inserts. Not for use with fin boxes that require a different bolt type or tool.
How long does shipping take to the US?
This product ships from China. Delivery typically takes 7–30 days depending on the shipping tier chosen at checkout. Orders may require manual approval for international shipping.
