                  What Customers Say
                  Summarized by generative AI from text of customer reviews

                  Customers say the self-tapping screws are versatile and effective for various applications, particularly in metal and wood projects. Many appreciate the ease of use and the time-saving feature of the self-drilling tip, which eliminates the need for pre-drilling in many cases. However, some users noted that the tips can be dull and may require pre-drilling for harder materials, leading to occasional breakage. Overall, the product is well-regarded for its reliability and performance in typical fastening tasks.

                  it does what it's made to do! used it to make a flower bed and it turned out great. I like that the head was a little wider so it didn't go all the way through the thinner corner peices.

                  I purchased these to attach foam insulation to a interior garage door. They worked extremely well, very sharp and penetrated the alum/steel easily with little effort. I am sure I will find a lot of other uses for this product.

                  Great Item, saved the day. I was installing chicken wire to use as a gutter guard to keep the leaves from clogging the super gutter. see picture below. This had a wide enough head to grab it, make it's own hole and finally keep the chicken wire from coming up. I just had to figure out how I can do this, and did it.
