1-1/2” Marine-Grade Stainless Steel Pontoon Deck Bolts

1-1/2” Marine-Grade Stainless Steel Pontoon Deck Bolts – Rust-Proof with Nylon Lock Nuts (100 Pack)

Looking for a deck bolt that will NOT rust? These 1-1/2” stainless steel pontoon deck bolts are built specifically for marine environments and come complete with locking nylon nuts for maximum holding power and vibration resistance.

Each bolt features a 1” flat flanged head with gripping teeth, designed to lay perfectly flat against your deck surface. This allows your pontoon carpet or flooring to install smoothly and flawlessly—no raised hardware, no uneven spots.

For proper installation, pre-drilling is required. Space holes approximately 12” to 16” apart, insert the bolt through the newly drilled hole, and secure it from the underside of the boat using the included nylon locking nut. Once installed, these bolts deliver a rock-solid hold that won’t loosen over time—even in rough water.

Constructed from marine-grade stainless steel, these fasteners are ideal for saltwater and freshwater applications, resisting rust, corrosion, and oxidation far better than standard galvanized or zinc hardware.

Perfect for pontoon floor replacements, new decking installations, dock projects, and marine repairs, these deck bolts provide professional results you can trust.
