One, the comprehensive force of the hard flat pad.
Generally speaking, when using Stainless steel flat washers, you must use two flat pads, one with a softer texture and one with a harder texture.
These two flat pads interact, among which the hard flat pad can protect the soft flat pad to a certain extent, increase the contact area with the component, disperse the pressure, and will not crush the component.
Second, increase the friction between the nut and the part.
After the flat washer is installed, the contact force between the nut and the mechanical parts can be increased to prevent the nut from being damaged by friction.
In addition to the above two functions, the function of Stainless steel flat washers is also reflected in the three words stainless steel, which can prevent the nut from being corroded by the rust of the mechanical parts.
This Stainless steel flat washers can well separate the nut and the part, so that even if the part is used for a long time, the screw will not be corroded by some harmful substances in the part.
Stainless steel flat washers are mainly thin pieces of various shapes punched out of steel plate, with a hole in the middle, which is mostly used to reduce friction, prevent leakage, isolate, and prevent pressure from loosening or dispersing.
The flat washer is round in shape and is mainly used to reduce pressure. It is usually used in conjunction with bolts, screws and nuts.
One of the generally used connectors is soft and the other is hard. Its main function is to increase the contact area, disperse the pressure, and prevent the soft from being crushed.
The stainless steel pad is to increase the fastening contact area. Spring pads are used in places with vibration to prevent loosening. No spring washers are required to tighten PVC flanges. The flat pad is to increase the contact area and prevent friction between the bolt and the workpiece; the spring pad is to prevent vibration from loosening;
When tightening the connecting parts, the main function of Stainless steel flat washers is to protect the surface of the connecting parts and prevent the bolts and nuts from scratching the surface of the workpiece during the tightening process;
However, some important connections, such as the place where the power is transmitted by the friction force generated by the pressure, cannot be used with spring pads, which are used to reduce the connection rigidity, and accidents may occur instead. You can do without spring washers.
When the strength of the connected parts is low, flat washers or flange bolts are used to increase the contact area. The flat washers mainly increase the contact area. The spring washers are anti-loosening, and the temperature of the medium is relatively large when there is vibration, pulse, and medium. When fluctuating, be sure to use spring washers. Stainless steel spring washers can increase the pre-tightening force and have an anti-loosening effect, while stainless steel flat washers do not.
