Stainless Steel

The Whitecap Marine Products Replacement Bolt for All Nylon Deck Hinges (SKU: 3000B) is a precision-engineered spare part designed specifically as a direct replacement for the original pivot or hinge bolt used in various Whitecap nylon deck hinges. It features a 3/16" diameter x 5" length threaded shank (with machine threading along the extended portion for secure fastening), topped by a rounded, slotted (flat-head/slotted drive) button or dome-style head for smooth operation and a clean appearance. The entire bolt is constructed from high-quality stainless steel (likely 316-grade or equivalent marine-grade SS, as is standard for Whitecap's corrosion-resistant hardware), providing excellent resistance to rust, pitting, and degradation in saltwater, freshwater, UV exposure, and harsh marine environments.

This bolt serves as the critical pivot pin/axle that allows the hinge to articulate smoothly, connecting the moving strap/leaf of the hinge to its base while enabling opening, closing, or sliding motion depending on the specific nylon deck hinge model.

Key Functions and Uses

• Primary function — Acts as the pivot bolt/pin in nylon deck hinges, allowing rotational or sliding movement between the hinge components for reliable operation.
• Replacement/repair — Ideal for replacing a lost, corroded, bent, worn, stripped, or broken original bolt in Whitecap nylon deck hinges to restore full functionality and prevent hinge failure.
• Marine deck applications — Commonly used on boat deck hatches, storage compartments, livewell lids, cooler covers, seat hatches, engine covers, or access panels where a low-profile, durable nylon hinge is installed for lightweight, non-corrosive performance.
• Side-mount or sliding deck hinges — Frequently pairs with models like Whitecap's side-mount/sliding nylon deck hinges (e.g., those specifying 3/16" x 5" bolt compatibility), enabling smooth sliding or pivoting action for flush or semi-flush lid operation.
• Angled or straight configurations — Compatible across various Whitecap nylon deck hinge styles (straight base, angled base, etc.), as it's marketed for "all nylon deck hinges" in their lineup.
• Maintenance and upgrades — Used during routine boat maintenance to upgrade from a potentially lower-grade or worn factory bolt to this stainless steel version for longer service life in exposed saltwater conditions.
• General marine hardware — While specialized for Whitecap nylon hinges, its dimensions and material make it adaptable for similar custom or DIY marine/boat hinge repairs where a 3/16" x 5" stainless slotted bolt is required.

This part emphasizes durability and corrosion resistance, making it well-suited for both freshwater and saltwater boating environments. Installation typically involves threading it through the hinge components and securing it (often with a nut or by threading into the opposing side, depending on the hinge design). Always confirm compatibility with your specific hinge model for best results.
