Self-tapping screws are favored in engineering construction because they do not require pre-drilling and are quick to install. Self-tapping screws can be used for wood, but need to choose the appropriate specifications according to the type of wood and the use of the environment. For pine, fir and other soft wood, self-tapping screws can generally be fixed directly, eliminating the need for pre-drilling steps to improve construction efficiency; and for hardwoods such as oak, cherry, if not pre-drilled, easy to cause wood cracks or screw damage. Therefore, in hardwood applications, it is recommended to drill holes before using self drilling screws.
In addition, the length, diameter and thread design of self-tapping screws are also very critical. Proper selection not only enhances the strength of the connection, but also extends its service life. In practice, engineers often based on the thickness of wood and load requirements to determine the specifications of the screws, if necessary, but also the use of special wood screws to ensure a solid connection. The construction process should also pay attention to the uniform force and prevent the problem of wood cracking.
Although the self-tapping screws in the wood fixed in a convenient advantage, but must be based on the characteristics of wood and engineering needs of scientific selection, reasonable operation, in order to ensure structural safety and durability. When selecting self-tapping screws, be sure to refer to the product description and conduct appropriate tests to ensure the best installation results.
