Aluminum Washers Bulk,Chrome Plated Washers,Large Bronze Washers

Generally, we often use some Chrome Plated Washers in the process of using screws, Large Bronze Washers and rubber washers.

What role can these Chrome Plated Washers bring us?

1. Prevent damage to objects caused by the use of spring pads during the removal of screws. In the process of use, we can first make the flat pad closely connected with the object and then use the spring pad outside, to prevent the damage caused by the spring pad to the object, give play to the effect of the spring pad, and also make the stress area more balanced. When used in this way, the spring pad can also prevent damage to the connected object.

1. It can increase the contact area. Generally, the contact area between the screw and the object is relatively small, so the acting force will be relatively small and easier to loosen. To make the screw lock the object more firmly, the gasket will be used to increase the contact area between the screw and the connection object.

1. It can be used in some special cases. For example, when there is no thread at the place where we want to self-tap the screw, we can use the gasket. In addition, when our screw is too long and wants to be more beautiful, we can use the gasket to make the screw look more beautiful.

1. It can help us increase friction. We all know that in the process of using high-strength bolts, they are fixed by friction. Sometimes we want to increase the friction between high-strength bolts and objects. We will choose to use gaskets to solve this problem. After testing, we found that the high-strength bolts with gaskets can greatly improve the friction.
