Recently, I purchased a 15-pack of galvanized screws for an industrial project .As a result of my tests I determined that these screws are fantastic for heavy-duty applications. They are incredibly durable and hold up well even in extreme conditions. Additionally, their galvanized coating ensures that they are rust-resistant and will last for a long time. The only con i could find is that they are a bit pricier than some other screws on the market. Overall, I highly recommend these screws for anyone looking for high-quality, industrial-strength fasteners..
