In the process of use, we can first connect the flat pad closely with the object, and then use the spring pad on the outside, which can prevent the spring pad from causing damage to the object, and also can play the role of the spring pad, and also can make the force area more balanced. This will also prevent the spring pad from causing damage to the connected object. Generally the contact area between the screw and the object is relatively small, so the force will be correspondingly small and easier to loosen. To make the screws lock the object more firmly, shims are used to increase the contact area between the screws and the object to be connected.
Self-tapping screws are a common fastener whose principle is a little different from other screws. The following is a detailed description of the principle of self-tapping screws:
Self-tapping screws are mainly composed of three parts: head, rod, and tail. The head is usually a hexagonal head or round head, the rod has a certain taper, and the tail has slotted or cross slots and so on. There is a tapered hole between the head and the rod of the self-tapping screw, which is one of the most important structures of the self-tapping screw.
