Engineered for Silence and Saltwater Endurance

Upgrade your vessel with the SHENG HUI Premium Anti-Rattle Hatch Latch. Forged from solid AISI 316 Stainless Steel, this heavy-duty fastener is specifically designed for the harsh saltwater environment, offering superior corrosion resistance and a lifetime of durability.

  • Precision Anti-Rattle Cam: The engineered cam mechanism provides constant tension to firmly secure hatches, eliminating annoying vibrations and noise while cruising at high speeds.
  • Mirror-Polished Finish: Each latch undergoes an extensive hand-polishing process to achieve a flawless mirror finish that resists dulling and complements modern yacht interiors.
  • Heavy-Duty Casting: Unlike stamped hardware, this cast 316 steel component provides the structural integrity required for critical hatch points.
  • Technical Specs: Overall length of 113mm with a 49mm width, ensuring compatibility with standard marine hatch configurations.

Certified to ISO9001 and CE standards, this hardware is the essential choice for boat owners seeking a blend of silence, strength, and sophisticated aesthetics.

Frequently Asked Questions

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.
