Brass Flat Washer Kit,Aluminum Washers Bulk,Chrome Plated Washers

In our daily life, we often see that the bolt connection pair adopts the form of hexagon bolt + nut + flat washer + spring washer. Should such a connection pair be used in shelf installation? Or to simplify the problem, should washers be used for bolted connections in shelves?

To understand this problem, we first need to know the function of the washer.

Flat washer

The functions of a Brass Flat Washer Kit are generally as follows:

1. When the bolt needs to be removed frequently, to protect the surface of the connected part from being scratched, it is generally necessary to place a Flat Washer Kit at the nut or bolt head.

1. In some joints where the friction coefficient is required to be more accurate, such as high-strength prestressed bolts, Flat Washer Kits need to be placed at the nut end, because in this case, bolts, nuts, and washers are provided by the same manufacturer, and the bolt manufacturer needs to deal with the nuts and washers accordingly to ensure the consistency of the friction coefficient between nuts and washers.

1. When the bolt strength is relatively high and the allowable compressive stress of the connected part is relatively low, it is generally necessary to add a Flat Washer Kit to increase the area of the pressure bearing surface. The larger the pressure-bearing surface is, the smaller the compressive stress is. Adding a Flat Washer Kit can effectively protect the workpiece.

1. On some occasions, to ensure the one-to-one correspondence of bolt holes between two connectors, we need to increase the diameter of the hole; Sometimes, to facilitate installation and adjustment, the bolt hole will be made into a long hole, so that the installation position of the workpiece can be adjusted within a certain range. When this bolt hole exceeds the standard requirements, it is necessary to use a Flat Washer Kit or thickened flat washer, or even multiple flat washers.

It can be seen that the function of the Flat Washer Kit is mainly to protect the workpiece surface and ensure the reliability of the connection so that the connection can meet the design requirements.

Spring washer

At the beginning of the invention, the Aluminum Washers Bulk has two main functions: one is to improve the fatigue strength of the connection, and the other is to prevent looseness of the connection.

So, when is the spring washer used? It can be used on the following occasions:

1. It is generally used on occasions with low requirements for bolt preload and small dynamic load.

1. When the clamping length of the bolt (the thickness of the fixed plate) is relatively short, the stress relaxation of the bolt is obvious, and the spring washer can make up for the stress relaxation.

Generally speaking, when the bolt has no pre-tightening force (installation torque) demand, it only needs to be tightened, and the fixed plate is relatively thin, the spring washer still plays a role and can play a certain anti loosening effect. Once there are torque requirements during bolt installation, the spring washer is not applicable.

Conclusion

After the above analysis, the conclusion is as follows:

1. TheChrome Plated Washers is generally needed, which can be used to protect the workpiece and improve the reliability of the connection. Generally, one is used at the nut end. When it is necessary to protect the workpiece surface, another is added at the bolt head end; At long holes or oversized round holes, thickened Flat Washer Kits or multiple Flat Washer Kits are generally used, depending on the situation;

1. Whether the spring washer is required shall be determined according to the specific situation. When the bolt has a clear demand for tightening torque (preload), the spring washer is not required, such as base fixation, anchor bolt fixation, and other important plate fixation; When the connection is at a noncritical point, the bolt can be tightened, or the position that cannot be tightened due to the special cold-formed thin-wall structure of the shelf (tightening will destroy the section shape of the connected member), the spring washer can be used to prevent looseness;

1. Flange nuts, bolts, and other special lock nuts do not need washers;

1. If there is a connection directly bearing frequent dynamic load on the shelf, from the point of view of connection reliability, fastening degree, and anti-loosening effect, the best solution is to adopt a high-strength bolt friction connection design, which can achieve the effect similar to welding.
