With the complexity of fastener products, many users will hesitate when choosing some bolt and nut accessories. For example, it will be difficult to select the flat washer. The following provides 5 flat washer selection criteria.

• When selecting flat washer materials, attention should be paid to the electrochemical corrosion of different metals in contact. The material of the flat washer is generally the same as that of the connected parts, usually steel, alloy steel, stainless steel, aluminum alloy, etc. Copper and copper alloy can be selected when there are conductive requirements.

• . the inner diameter of the flat washer shall be selected according to the larger value of the thread or screw diameter, and the larger value shall be selected for the outer diameter of the soft connected material (such as composite material) or the spring washer.

• When the w washer is placed on the bolt or screw head, in order to avoid the interference between the fillet under the head and the washer, the flat washer with inner hole chamfer can be selected.

• Steel washers shall be used for important bolts with large diameter or to increase the anti extrusion capacity. Steel washers shall be used for the connection of tension bolts or tension shear composite bolts.

• . special gaskets shall be used for special requirements. Copper gaskets can be used if conductive is required; Available sealing gaskets with air tightness requirements.

What is the difference between gasket and sealing ring?

The small gaskets and sealing rings that do not look impressive play a big role. The sealing ring is specially used for sealing, and the sealing effect is good. The gasket is also divided into non-return gasket, flat gasket, spring gasket, etc., which may not have sealing effect. The specific differences between the two are as follows:

The difference in shape and composition between washer and seal ring: washer refers to the part padded between the connected part and the nut. Seal ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap. Generally, it is a flat metal ring.

Functional difference between washer and sealing ring: washer is used to protect the surface of the connected part from scratch by the nut and disperse the pressure of the nut on the connected part. The sealing ring prevents the leakage of lubricating oil and the invasion of foreign objects.

The selection of sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the service performance of the sealing ring. In comparison, the influence of gasket material selection on its function and service life is far less than that of sealing ring.

In addition to the above, more attention should be paid to the selection of flat washers. The most basic thing is to see whether the flat washers lack edges and corners, and whether the flat washers have gaps. The selection of flat washer depends on the material and performance grade. When selecting the material of the flat washer, you need to select it according to the demand for the surface hardness of the flat washer, the specific occasion, and your own budget. More knowledge about the selection of flat washers will be shared with you in the future.
