Rubber Sealing Strip Factory Introduces Why Fasteners Use Washers

Update:19 Aug

Does the rubber Sealing Strip Factory introduce why fasteners use washers?
 
1. If the base material is very soft and the periphery of the hole where the fastener is installed has been damaged, the problem of pull-through failure may occur during the screw-in process of the fastener. This is because in most cases, the application of force during tightening is sufficient to pull the fastener through the material master, and the presence of the washer helps to create less build-up pressure.
 
2. Some washers have a special structural design to prevent the nut from loosening. We commonly call this type of washer a lock washer, and there are many types of structures, such as open type, star type, and wave type. This type of lock washer needs to be used in conjunction with the nut.
 
3. If the base material is very soft, the surface of the base material will be damaged during the screwing process of bolts or screws. By using washers, this pressing force can be distributed over a larger area, avoiding damage to the motherboard surface.
 
4. When the surface of the motherboard into which the bolts or screws are screwed is not smooth and flat, the head of the fastener is likely to be stuck. By using washers, the surface of the bolts or screws can be guaranteed to slide and the installation becomes easier. Washers are very common standard parts, and we often find them in the tightening process of threaded connections such as bolts and nuts. It can be said that washers are always used with threaded fasteners such as bolts or screws.
