Hand Fin Screw Northcore US Box

Hand Fin Screw Northcore US Box

The Northcore fin bolt is the essential replacement accessory for securing your center fin to a standard US Box. Crafted from high-quality stainless steel and equipped with a rubber washer, it guarantees a reliable and secure fit for all your longboard or SUP sessions.

Detailed Description

Built to last, this bolt and plate are machined from 316 marine-grade stainless steel, offering total resistance to corrosion.

The standout feature of this model is the integrated rubber O-ring. This small detail makes all the difference: it exerts constant tension that prevents the screw from loosening due to vibrations and pressure from the moving fin. It ensures a stable fit throughout your session, even in heavy wave conditions.

• Enhanced Safety: Rubber washer included to prevent accidental loosening.

Breizh Rider Team Advice

• Field Expertise: We’ve all lost a fin because a screw backed itself out. The rubber washer provides real extra security that we systematically recommend at the shop.

• Maintenance: Simple hand-tightening is usually enough thanks to the washer. Still, always check the tightness before hitting the water. Like all gear, a quick rinse with fresh water after your session will prevent salt from crystallizing and seizing the bolt.

• Need a Guide: If you have any doubt about compatibility with your US Box, come see us at the shop in Douarnenez—we can test it right then and there.

• Shipping from Brittany: This item is in stock in Finistère. We ship quickly throughout Europe so you don't get stuck on the beach.
