The Sunflower Screw

The sunflower screw is a simple yet important invention. It was first developed in the early 20th century in the United States by inventor William R. Harding. It is commonly used in fastening applications in a variety of industries and fields, including automotive, aeronautical, military, and industrial.

The sunflower screw is a specialized type of screw designed to create a uniform torque in a given application. This feature is achieved by its unique configuration, which includes a triangular-shaped head and an off-center thread pattern. The threads of the sunflower screw feature a series of concentric circles, which create a spiral pattern when the screw is inserted. This spiral design allows for even distribution of torque, which reduces the risk of over-torquing or premature failure of the material being tightened.

The sunflower screw has a number of advantages over traditional screws. One is that it is lighter than traditional screws, reducing the possibility of damage to the material being tightened. Another advantage is its ability to grip a greater area, allowing for more secure fastening. Additionally, the sunflower screw is more resistant to corrosion, making it an ideal choice for wet applications as well as outdoor-use. This corrosion-resistant property also allows for longer periods of use in more extreme conditions.

When determining the size of a sunflower screw, it is important to consider both the length of the screw and the thread size. The thread size should be larger than the material being fastened, but the length should be determined by the individual application. In some applications, additional lengths may be necessary, increasing the thread size accordingly. Other Fastening technology, such as lock washers, may also be necessary depending on the specific application.

The sunflower screw is a simple yet important invention that has enabled countless industries to produce better, safer, and more secure products. Its lightweight design, even torque distribution, and corrosion-resistant properties make it a popular choice for a wide range of fastening applications. If you’re in need of a reliable fastening solution, you can’t go wrong with the sunflower screw.

The Screw Lilies, commonly known as lilium speciosum, are one of the most easily recognizable parts of the Lilium family. Also known as the Elegant Lily or the Showy Lily, these plants can be found stretching their long stems and tall blooms across many gardens and yards.

The flowers of the Screw Lilies are generally large and very showy, with spades and star-shaped petals in shades of orange, yellow and white. These flowers can be seen through the summer and autumn months and the plants themselves can grow up to about 4 feet in height.

The Screw Lilies are reliable in their blooming, with often over a hundred blossoms on each stem. They are easily propagated through division of the tubers in early spring. Like other lilies, it is best to plant them in areas that are relatively sunny and in soils that have good drainage. When planted in a location that is too moist, their roots may rot and they will not survive.

The Screw Lilies can be used to create some stunning effects in a garden, especially with the backdrop of a strongly coloured fence or wall. As long as they are properly sited and the soil drains well, they can make a great addition to your garden or yard.
