Self-tapping screws are a popular choice for many different applications. They are convenient and easy to use, However, like any other type of fastener, self-tapping screws also have some potential disadvantages that need to be considered.
1. Easy to break
Self-tapping screws are mostly made of high-speed steel or carbon steel. Although the hardness of this material is good, it also increases its brittleness. Therefore, when using self-tapping screws, once they encounter hard objects during the tightening process, self-tapping screws are easy to break.
2. Easy to slip
When installing self-tapping screws, it is necessary to pre-drill holes in the wood, and ensure that the diameter of the pre-drilled holes is equivalent to the diameter of the screws, otherwise it is easy to cause the screws to slip. In addition, the places where there are no threads on the surface of the screws are prone to sliding, resulting in the inability to insert the screws, and if the force is not enough, it is also easy to slip.
3. Drilling is easy to clog
Self-tapping screws need to pre-drill holes in the wood. When the wood is relatively hard, a slight deviation of the self-tapping screws can easily cause the hole to be clogged. At the same time, because the position of the hole is relatively fixed, it is easy to be retained by debris such as wood chips and dust, making the installation process difficult.
Although self-tapping screws have great advantages in terms of easy installation and high efficiency, these shortcomings should also be noted during use to prevent unexpected situations. It should be noted that self-tapping screws with special requirements need to be carefully considered when selecting to avoid quality problems.
