We recently used these stainless Phillips screws for a project and were thoroughly impressed with their quality and performance .Based on our own experience we can confidently say that these screws are a great investment for any industrial and scientific application. the screws were easy to work with and held strong, even in tough environments. The only drawback we noticed was the slightly higher price point compared to other screws on the market, but the added durability and reliability make it worth the investment..
