As a loyal customer in the Industrial and Scientific world i was excited to try these hooks .However, as a result of my tests, I determined that these hooks are far from trustworthy. While the hooks did have a strong grip, they quickly rusted, making them unusable. The frustration of having these hooks fail during important material handling tasks outweighs any initial benefits. Overall, I would not recommend these hooks to anyone in need of reliable securing straps..See full review
