At 3-1\/8 inches with an 840 pound breaking strength and a 168 pound safe working load, it handles everyday clipping and securing jobs all over the boat, from cover straps to fender lines. Simple, dependable, and cheap enough to keep a few on hand.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis little zinc-plated spring snap hook from T-H Marine is one of those parts you don't think about until you need one, and then you need three. It's a gourd-shaped safety hook with a self-closing spring gate, 3-1\/8 inches long, built for the everyday clipping, securing, and quick-connect jobs that come up all over a boat. Nothing fancy here. Just a dependable snap that does its job and gets out of the way.\u003c\/p\u003e\n\u003cp\u003eHere's what you're actually buying. The hook carries an 840 pound breaking strength and a 168 pound safe working load. That gap matters, so it's worth a minute. Breaking strength is the load at which the metal finally gives up. Safe working load is what you should actually rig it for, day in and day out, with a healthy margin built in. T-H Marine rates this one at a 5 to 1 safety factor, which is where that 168 pound number comes from. Plan your rigging around it and you've got room to spare.\u003c\/p\u003e\n\u003cp\u003eThe gate is spring loaded and self-closing. Push a line, a ring, or a D-ring into the throat and the gate snaps shut behind it. Let go and it stays put. That's the whole point of a spring snap over a plain open hook. It won't walk off the attachment point when the boat's slamming through chop or a line goes slack and snaps tight again. And it's one-handed, which you'll appreciate the moment your other hand is busy holding a cover or a fender.\u003c\/p\u003e\n\u003cp\u003eThe gourd shape is that pinched, figure-eight profile. Wider throat at the hook end, narrower eye up top. In practice that means it clips onto larger rings and bails cleanly while keeping a compact tail for whatever line or shackle you're tying off to. The eye takes a split ring, a shackle, or a knot without binding, and it sits flat against a strap instead of flopping around.\u003c\/p\u003e\n\u003cp\u003eThe finish is zinc plating over steel. Zinc gives you real corrosion resistance for freshwater boats, trailer rigging, dock carts, cover straps, and any gear that sees spray but gets rinsed and stored dry. Now some straight talk, because we'd rather you buy the right part once. Zinc-plated steel isn't stainless. If you clip this somewhere it sits in salt spray day after day with no rinse, it'll eventually show surface rust. For permanent saltwater exposure like that, a stainless snap is the better call. For everything else, this one holds up fine and costs a fraction of the price.\u003c\/p\u003e\n\u003cp\u003eSo where does it earn its keep? Cover and canvas tie-downs, bimini straps, fender lines, flag halyards, safety lanyards, gear bags, ditch bags, and about a hundred little clip-this-to-that moments a season. Keep a couple in the console drawer and a couple in the rigging bag. They disappear into a tackle bag and weigh next to nothing. They're cheap enough to stage all over the boat and handy enough that they never go to waste.\u003c\/p\u003e\n\u003cp\u003eA quick word on sizing. At 3-1\/8 inches this is a mid-size snap. Big enough to grab with cold hands and clip onto a decent ring, small enough that it isn't clunky hanging off a strap. If you ever find yourself loading it past that 168 pound working number, step up to a larger snap or a properly rated shackle instead. A snap hook is a quick-connect, not a lifting point, and it isn't built to take shock loads up at its breaking limit.\u003c\/p\u003e\n\u003cp\u003eThere's nothing to install. It's grab-and-go. If you want to match this exact size and rating down the road, the manufacturer part number is BE-HA-54330-DP. And because it's a standard T-H Marine rigging piece, it works right alongside the rest of your dock lines, bungees, and deck hardware.\u003c\/p\u003e\n\u003cp\u003eLittle parts like this are easy to overlook until the one you've got lets go at the worst time. A good spring snap is cheap insurance. This one gives you a clear load rating, a gate that actually stays closed, and a finish that shrugs off the usual freshwater wear. Buy a few, stash them where you'll reach for them, and forget about it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSpring-loaded, self-closing gate keeps lines, rings, and D-rings captured even through chop and slack-load cycles\u003c\/li\u003e\n  \u003cli\u003e840 lb breaking strength with a 168 lb safe working load, a 5 to 1 safety factor for everyday rigging\u003c\/li\u003e\n  \u003cli\u003e3-1\/8 inch length, a mid-size snap that's easy to grab one-handed yet compact on a strap\u003c\/li\u003e\n  \u003cli\u003eGourd-shaped profile gives a wider hook throat and a narrow eye for clean tie-offs\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel resists corrosion on freshwater boats, trailers, and rinsed-and-stored gear\u003c\/li\u003e\n  \u003cli\u003eOne-handed operation for quick clip-and-go jobs when your other hand is full\u003c\/li\u003e\n  \u003cli\u003eManufacturer part number BE-HA-54330-DP for easy reordering of this exact size and rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized T-H Marine Supplies reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat's the difference between the 840 pound breaking strength and the 168 pound safe working load?\u003c\/summary\u003e\n    \u003cp\u003eBreaking strength is the load at which the hook finally fails.
