Plastic Push Rivets, aka Pine Tree Rivets, comes in several sizes, sold as single rivets. Typically they are a no-tools-no-drilling mounting hardware used for a pre molded or pre drilled hole. They are used for seat pads, and other kayak features like side net bags and thigh pads. The ridges on the shank will fit very snuggly into the hole and resist removal. Insertion is easy, removal may require some prying and pulling with hand tools and will probably damage the rivet.
Please carefully select your size below before putting into shopping cart. It is wise to remove one from the kayak and compare to the photo.

Please Note: The above use suggestions are not absolute. Any type of Push Rivet, in any size, can be found on any make, model or year of kayak. It is up to you select the correct size Push Rivet based on your own measurements and needs. These are best used on existing pre-molded or pre-drilled holes. Take extra care if drilling new holes. Push rivets should fit very snuggly into drilled holes. Drill a test hole in scrap to ensure a good fit. Extra Push Rivets are wise to have on hand.
