Perko Cover Bolt Complete Sizes 8, 9 & 10

The Perko Cover Bolt Complete Sizes 8, 9 & 10 is an essential replacement hardware component for marine applications where deck hardware and fittings require secure fastening. After years on the water, any boater knows that corrosion-resistant fasteners are non-negotiable—whether you're securing cleats, railings, pulpits, or through-hull fixtures. Perko has built a reputation for manufacturing marine-grade hardware that withstands saltwater exposure and constant movement, making this complete bolt assembly a reliable choice for vessel maintenance and repair.

This cover bolt assembly comes in three size options—8, 9, and 10—allowing you to match your existing deck hardware or replace worn fasteners across multiple fittings. The complete design includes the bolt body and cover, engineered to resist the galvanic corrosion that occurs when dissimilar metals contact saltwater and fiberglass. Perko's fasteners are typically manufactured from stainless steel, ensuring minimal degradation even in harsh offshore conditions where standard hardware would fail within a season.

This product suits restoration work, routine maintenance, and custom rigging projects where original Perko hardware is already in service or where marine-grade fastening standards are required. Compact at 3 x 1 x 3 inches and lightweight, it's easy to carry aboard and store in your emergency repair kit. Whether you're a commercial fishing operator, cruising sailor, or recreational boater, this cover bolt assembly is a reliable choice for your marine needs.
