Introduction to the design and use of spring washers-hardware

From the design perspective, the spring washer has a pre-tension, and after being compressed, it rebounds. In actual use, due to the characteristics of the thread, the nut can easily rotate in the direction of the spiral after being tightened, causing the nut to loosen. In order to solve this problem in the early days, spring washers appeared. Due to the pre-tension of the spring washer, after the nut compresses the spring washer, under the action of the pre-tension, the triangular screw buckle in the nut and the side of the triangular screw buckle of the bolt are tightly attached to each other. Under the action, the nut no longer appears loose. The ordinary washer (also called round hole washer or flat washer or ordinary washer) is a support under the pretension of the spring washer, which increases the pressing area of u200bu200bthe pretension of the spring washer. Generally speaking, spring washers and ordinary washers are used together, and it is unreasonable to use ordinary washers alone. Of course, the design and actual needs of individual applications are not excluded. For example, when the plastic shell of an electrical appliance is screwed with a self-tapping screw, the separate ordinary washer below is just to increase the force-bearing area.
