Description:
The Unifiber Fin Screw M6x100 is a precision replacement fastener designed to secure fins and fin boxes on watersports boards. Machined from marine-grade stainless steel for high corrosion resistance, this M6 x 100 mm screw provides long-lasting strength and dependable clamping force in saltwater environments. Its accurately cut thread and smooth shank minimize galling and allow easy installation and removal with common hand tools.

Lightweight yet robust, it is an ideal spare part for surfers, SUP riders, windsurfers and sailors who need a reliable anchor point for their fins. The straightforward design also makes it compatible with most M6 fin box assemblies and aftermarket fin fittings.
