Designed for fill caps with 1-3\/16\" holes on center, this key delivers a clean, tight engagement that protects the cap's drive recesses from wear over years of use.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInvestment cast 316 stainless steel\u003c\/strong\u003e — greater corrosion resistance than formed 304 SS; holds up in harsh saltwater environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision fit for 1-3\/16\" hole-on-center fill caps\u003c\/strong\u003e — works with all fill caps using this standard spacing, including Sea-Dog hose deck fills and most compatible brands\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInvestment casting process\u003c\/strong\u003e — produces tighter dimensional tolerances than stamped or formed keys, for a more secure fit and less cap wear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact and lightweight\u003c\/strong\u003e — easy to stow alongside the fill hardware or in a cockpit locker\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e This is the right key when the boat has quality cast stainless deck fill hardware and the owner wants a matched, long-lasting tool rather than a generic universal key. The 316 SS construction makes it particularly well-suited for offshore or bluewater boats where hardware is exposed to sustained saltwater spray and the higher corrosion resistance of 316 over 304 is worth specifying. It's also the correct choice as a replacement key for Sea-Dog hose deck fills — the 1-3\/16\" hole-on-center spec matches that hardware family directly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePair with Sea-Dog deck fill hardware:\u003c\/strong\u003e \u003ca href=\"\/products\/8210051268644\"\u003eSea-Dog Locking Deck Fill – Diesel\u003c\/a\u003e, \u003ca href=\"\/products\/11077631934500\"\u003eSea-Dog Locking Diesel Hose Deck Fill w\/Keys, 1-1\/2\" Hose\u003c\/a\u003e, \u003ca href=\"\/products\/11077631868964\"\u003eSea-Dog Locking Gas Hose Deck Fill w\/Keys, 1-1\/2\" Hose\u003c\/a\u003e, or \u003ca href=\"\/products\/11120014721060\"\u003eSea-Dog Angled Hose Deck Fill Replacement Cap\u003c\/a\u003e.
