Package Contents: 10-pack of hump fasteners with screws (other items not included). These hump fasteners, specifically designed for watercraft, are made of high-strength, one-piece molded nylon. They are durable, impact-resistant, and have a smooth, waterproof, and corrosion-resistant surface.

The design allows for smooth rope winding, with pre-drilled standard screw holes on both sides. The complete set includes a sufficient number of matching stainless steel self-tapping screws. These stainless steel screws are rust-proof and salt spray resistant, making them resistant to rust and jamming in humid marine environments. During installation, simply attach the clips to the hull and tighten the screws for a secure fixation that won't easily come loose. Suitable for various watercraft such as kayaks, canoes, small fishing boats, inflatable boats, and yachts, these clips can be used to secure paddles, tow ropes, waterproof storage bags, lifelines, sunshade straps, and other accessories. They neatly organize various ropes, preventing tangling. The thickened nylon clips offer stable load-bearing capacity, and the rounded edges prevent damage to ropes. The uniform clip specifications ensure neat and aesthetically pleasing batch installations. Their compact size saves space on the boat, and easy assembly and disassembly require no complicated tools. The waterproof and weather-resistant material is suitable for outdoor use in constant sun and rain conditions. These are practical and commonly used fixing hardware accessories for kayak and small boat modifications and hull accessory additions.
