Marine Hardware • Top Pick
Check PriceHatches clattering like a bag of wrenches in a gale. It drives a skipper mad. Loose lids mean leaks. Leaks mean rot. Your deck hardware is failing because you trusted plastic or cheap ‘mystery metal’ from a big-box store. Absolute junk.
Generic latches vibrate loose. They snap when you need them shut. Saltwater eats low-grade steel for breakfast. You’re looking at tea-staining, pitting, and eventual failure. A loose hatch isn't just a noise—it's a safety hazard. Fix it right or don't bother leaving the slip.
The Marine Anti-Rattle Hatch Latch - AISI 316 Stainless Steel (113mm) is the only gear for a proper vessel. It's forged for the heavy stuff. No plastic. No rattling. Just solid, 113mm marine-grade hardware that stays shut. Pair it with a Marine Offset Hinge - 316 Stainless Steel Heavy-Duty (85x40mm) or a 316 Stainless Steel Boat Butt Hinge - Heavy-Duty Cast (50x50mm) to secure your deck properly.

- AISI 316 Stainless Steel
- An austenitic chromium-nickel stainless steel containing molybdenum. It resists corrosion from chlorides and saltwater better than 304 grade.
- Cam Mechanism
- A rotating or sliding piece in a mechanical linkage used to transform rotary motion into linear motion, providing the 'pull-down' tension required to stop rattles.
FAQ
- Will this latch rust if used in saltwater environments?
- No, this latch is forged from solid AISI 316 stainless steel, which contains molybdenum to specifically resist pitting and crevice corrosion in high-salinity marine environments.
- How does the 'anti-rattle' feature actually work?
- The latch utilizes a precision-engineered cam mechanism. When closed, the cam applies downward tension on the strike plate, which compresses the hatch seal and prevents the metal-on-metal vibration that causes rattling while the boat is underway.
- Does it come with the necessary mounting screws?
- The latch features four countersunk mounting points (two on the base and two on the strike plate). While screws are generally not included to allow for different hull thicknesses, it is designed to accept standard #8 or #10 stainless steel flat-head fasteners.
