The Homesmiths ST Screw 1-1/4 X 8 is the right screw for making joins in your professional as well as DIY home projects. The screws are made from fine quality steel, which ensures that the screws are strong as well as resistant to corrosion. As the screws tap their own holes, the layers of the thread structure and of the material being joined hold each other firmly. This makes the join stronger and keeps it in place until the screw is not deliberately removed. .(1)Product dimensions are 1-1/4 X 8(2)Made from superior quality steel(3)Is resistant to corrosion and durable(4)The thread structure is fine and equally spaced(5)The threads span through the entire length of the screw.
