I was hesitant to purchase these screws for my latest project but I`m glad I did. Based on my observations, they are well-made and easy to install. The QuikGuard coating is a nice touch and seems DURABLE.I appreciate that they come in a bulk pack, which is convenient for larger jobs. However, they are a bit pricier compared to other options. Overall, I recommend these screws for anyone in need of reliable and sturdy fasteners for industrial and scientific use..
