The Harmony Rivet pack contains 80 rivets for use on composite canoes with aluminum gunwales.
Although I was totally unsatisfied with this product... It by no means reflects on Austin Kayak! Superb customer service and awesome attention to detail. A+++++ service!
Harmony Rivets... I would not recommend using these for any composite kayak install. Your basically getting the same rivet you can get at a big box store painted black. Instead get the tri grip rivets made by yak gear... They are alluminum, long and have a rubber o- ring at the head! I would only use these rivets for sheet metal.
