A spring washer assembly is placed under the nut to prevent loosening of the nut.

The difference between spring washers and flat washers

The spring washer is used for anti-loose, the flat washer has no anti-loose function, the flat washer only increases the contact area, and the spring washer can be loosened. For example, the bolt connecting the motor to the base is generally spring-loaded, because the motor vibrates without a spring pad. The nut will loosen. The fasteners on the equipment with vibration are equipped with spring washers. Generally, there is no need to add gaskets on the flanges. There is no relationship between the springs on the flanges and the medium through which the pipes circulate. Pulsed, preferably with spring washers, and high-speed fluid, the caliber changes frequently. Do not generalize. On some valves, the stuffing box gland flange needs to be spring-loaded. Spring washers are quick and easy to automate the selection. Inclusion.

The flat pad is to increase the fastening contact area. The spring pad is used for the place with vibration to prevent loosening. The PVC flange is not required to be spring-loaded. The flat pad is to increase the contact area and prevent the friction between the bolt and the workpiece; the spring pad is to prevent the vibration from loosening;

The main function of the flat washer is to protect the surface of the joint from scratching the surface of the workpiece when the bolt and nut are tightened; the spring washer is loose. However, some important connections, such as the place where the friction is mainly transmitted by the friction, can not use the spring pad, and it is easy to reduce the rigidity of the connection. Spring washers are not required. When the strength of the connected parts is low, flat pads or flange bolts are used to increase the contact area. The flat pads mainly increase the contact area. The spring washers are loose-proof, and there are vibrations, pulses, and medium temperatures. Always use a spring washer when fluctuating. The spring pad can increase the pre-tightening force and has a anti-loose effect, while the flat washer does not.
