YKK Snap Fasteners

SNAD® Snap Adhesively Attached

YKK introduces its plastic adhesive snap components for the marine industry. Unlike traditional metal screw studs used for marine applications, this product will not snag clothing or deteriorate from exposure to sunlight, sand and dirt. Plus, its unique dome shape enables it to be walked on without causing pain.

What's even more amazing about the snap component is how it is secured to boat surfaces. On the underside of the plastic dome is a pad of 3M, VHB™ acrylic conformable foam adhesive tape that enables the snap to adhere to boat surfaces without having to drill a hole. For more than 20 years the VHB™ product line has proven to be tough in marine, automotive, medical, aerospace, and architectural applications. YKK has adapted it to use with its patented design to bring flexibility and convenience to the marine industry. All one must do is simply clean the surface to which the snap is to be applied, peel off the protective paper backing, position and firmly hold the snap in place and release.

No tool, no wait, no splits, no hole!


  • Use wherever a conventional screw stud might be used:
    • Marine carpeting for decks
    • Cushions and seating
    • Canvas for decks, bulkheads or panels
    • Console covers
  • Use to replace existing screw studs without the need to fill-in the screw hole.
