Most eye bolts with small thick bases can easily deform under heavy loads, so we made thicker self-tapping eye screws. The upgraded version is 10mm thick and can hold up to 700 pounds. It is safer when hanging objects with high load requirements. The eye of the heavy-duty eye hook is different from other self-tapping eye hooks that are not completely enclosed. The fully enclosed eyelet design prevents the eyelets from deforming during use and improves safety and load-bearing capacity. The screw eye hooks are made of high quality 304 stainless steel, making these screw eyes strong and preventing the steel from rusting. Even when used outdoors, you don't need to worry about rust. Our eyebolts are perfect for indoor and outdoor projects, whether in sleet, rain or wet conditions. It also works well for bundling hardware commonly used in construction and decoration and for securing cable wires. Mainly, it can provide a wide range of uses in daily life, such as camping and a good DIY tool when traveling. You can hang swings, hammocks and other items anywhere you want. Easy to install: Based on our high-quality stainless steel tip, you can bite into wood, plywood or drywall without stripping. Additionally, you can use a wrench to screw the hook into the wood, drill the hook into a concrete wall, or use a soft hammer to gently insert it directly into the wood.
