Sea-Dog Universal Deck Fill Key & Multi-Tool – 304 Stainless Steel
A hardworking multi-tool built around the deck fill key — one of the most-used tools on any boat. Stamped from corrosion-resistant 304 stainless steel, this key opens Sea-Dog fuel fills and most other standard deck fill caps, while six additional functions mean it earns its place in any onboard tool kit.
- Universal deck fill fit — opens Sea-Dog fuel fills and most competing deck fill cap styles
- Shackle key — opens standard snap shackles without a separate tool
- Straight blade screwdriver — handles common flathead fasteners found throughout deck hardware
- 5/16" and 7/16" hex head wrenches — fits the most common hex bolt sizes on deck fittings and hardware
- Bottle opener — because every tool kit deserves one
- 304 stainless steel construction — stamped for strength, corrosion-resistant for long-term marine use
Parts Desk Insights
Best use case: This is the right key for boats running Sea-Dog deck fills — it's purpose-built to fit that hardware family and covers the most common fill cap styles from other brands as well. The built-in shackle key and hex wrenches make it genuinely useful beyond just opening deck plates, which is why it's a strong choice as a single compact tool to keep clipped to a gear bag or stored in a cockpit locker. It's particularly well-suited for sailors who regularly work with shackles and deck hardware during rigging or sail changes.
Pair with Sea-Dog deck plates: Sea-Dog Screw-Out Deck Plate 4" – Black, Sea-Dog Screw-Out Deck Plate 4" – White, Sea-Dog Screw-Out Deck Plate 6" – Black, or Sea-Dog Screw-Out Deck Plate 6" – White. For an adjustable-fit key that opens larger plates up to 6", see the Sea-Dog Adjustable Bronze Deck Plate Key. For a cast stainless option, see the Cast Stainless Deck Plate Key.
