Washer application
The spring washer device is under the nut to prevent the nut from loosening. The hexagon slotted nut is specially used with the bolt with hole at the end of the screw to insert the cotter pin from the groove of the nut into the hole of the screw and prevent the nut from loosening automatically. It is mainly used in the occasions with vibration load or alternating load.
In mechanical design and manufacture, the methods to prevent the nut (or bolt) from loosening automatically are as follows:
1. Padded spring washer（ Easy to do)
2. Use hexagon slotted nut and split pin（ Processing procedure increased year on year)
3. Pad the stop washer（ Processing procedure increased year on year)
4. The hexagon head of the hexagon bolt is perforated to insert the steel wire（ Processing procedure increased year on year)
Flat washer is also called flat cushion meson. It is mainly made of iron plate. Its shape is generally round or square, with a hole in the middle. This hole size specification is generally corresponding to the bolt diameter, and can also be formulated according to customer requirements. Under normal circumstances, the same size of bolt is suitable for flat washer with the same hole diameter, different outer diameter and thickness. For example, the hole diameter of flat washer for the bolt of m10mis 10mm, but the outer diameter and thickness are not fixed.
Galvanized flat washer
Flat washers are often used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. Many materials and structures have such components to perform similar functions. Limited by the material and technology of threaded fasteners, the bearing surface of bolts and other fasteners is not large. Therefore, in order to reduce the compressive stress on the bearing surface and protect the surface of the connected parts, flat washer is often used in the use of bolts. Therefore, flat washer is an essential auxiliary accessory in bolt fasteners.
304 stainless steel flat washer
According to the different compression limit and service environment, the material of flat washer is also different. Commonly used flat washer materials are iron, carbon steel, stainless steel, copper, plastic, etc., flat washer size is generally divided into standard size, increase, thickening, increase thickening, etc.
