YKK SNAD Black 40mm Adhesive Backed Domed Socket

Tested by marine canvas professionals as a high performing metal snap alternative that attaches to a surface with adhesive rather than screws - very forgiving of the DIYer! Unlike traditional metal sockets used for marine applications, these adhesive backed fasteners 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.

The SNAD socket secures to boat surfaces with a pad of 3M VHB acrylic conformable foam adhesive tape (located on the underside of the domed plastic) 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 the VHB adhesive with its patented design to bring flexibility and convenience to the marine industry. Simply clean the application surface, peel off the protective paper backing, position and firmly hold the snap in place.

The YKK SNAD Socket can be used wherever a conventional screw stud might be used. For example, use adhesive backed fasteners for marine carpeting for decks, cushions and seating, canvas for decks, bulkheads, or panels and console covers. You can also use SNADs to replace existing screw studs without the need to fill-in the screw hole.

Surface Preparation Instructions and Application Guidelines: Snap components will adhere to most clean, dry and well-unified surfaces. Typical surface cleaning solvents are a 50/50 Isopropyl Alcohol (rubbing alcohol) water mixture. Let air dry or wipe dry with a soft lint-free cloth before applying fastener. Remove liner from back of disk. Position snap and roll into place. Press down on the snap working all the way around the snap and in the center to secure to substrate.

Application Pressure: Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops a better adhesive contact and thus improves bond strength.

Application Temperature: Ideal tape application temperature range is 70F to 100F (21C to 38C).

Dwell Time: After application, the bond strength increases and approaches the ultimate bond strength after 72 hours at 70F (21C). Typical bond strength build-up: 20 minutes equals 50% bond strength, one hour equals 75% bond strength, one day equals 90% bond strength, and three days equals 100% bond strength.
