Replacement Mast Brass Barrel Nuts

Replacement brass barrel nuts for UniFoil carbon masts — the captive hardware that anchors your mast bolts.

Barrel nuts seat inside the mast and accept your mounting bolts, locking the mast to the fuselage. Over time and repeated assembly they can wear or get lost — this set keeps a fresh, ready replacement on hand so a worn nut never ends a session.

What's included

• [QTY] × Brass barrel nuts

Great for

Replacing worn or lost barrel nuts — the most common reason riders order spare mast hardware.

Travel and demo days — keep a set in the board bag so a missing nut never sidelines you.

Routine maintenance — refresh hardware that's seen heavy assembly and disassembly.

Compatibility: fits all UniFoil carbon masts.

Pro tip: a light coat of TEF-GEL on the threads helps prevent corrosion and seizing in saltwater — good practice with any mast hardware.
