Curved Single Coil Spring Lock Washers

Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products, which are characterized by low cost, easy installation, and are suitable for parts that are frequently mounted and dismounted. Spring washers in the screw industry, are often called spring washers. It is made of stainless steel and carbon steel, carbon steel is also known as iron. Generally used spring washers specifications size M3,M4,M5,M6,M8,M10.M12,M14,M16.Saddle spring washers are a kind of washers, flat washers are generally used in the connection of a soft texture, a hard texture is more brittle, Its main role is to increase the contact area, dispersion of pressure, to prevent the texture of the soft pressure bad. Saddle spring washers a similar to horseshoe-shaped washers, mainly used to prevent the bolt from loosening, The principle of its work is to use the saddle-shaped special structure, to increase friction, to prevent fasteners from falling off. Saddle spring washers and other waveform spring washers, stainless steel spring washers have a better anti-loosening function.    

Name： DIN137A saddle-type elastic washers
Standard: DIN137A
Material: carbon steel
Saddle-type spring washers, belonging to the German standard, according to the appearance of their type can be divided into A type and B type. Compared with the national standard DIN137, saddle-type spring washers are also used to avoid the loosening of bolts and nuts in vibration after assembly. With DIN128 use, the spring washer by the external load and reserves of potential energy converted to elastic force is conducive to maintaining the bolt preload, to play a certain locking effect, but in a large vibration in the radial load, its locking effect on the device is not ideal. The washer is recommended for bolts/nuts with strength class 8.8 or lower. The surface treatment is commonly blackened and mechanically galvanized. As the material is spring steel, its hardness is generally greater than 400HV, Galvanized coating is prone to the risk of hydrogen embrittlement, so it is not recommended to use the coating. The hardness of this type A is generally 430HV-530HV. This washer can also be used for left-hand threads
