ASTM Stainless Steel Washers Serrated Tooth Knurled Disc Spring Type M2

DIN9250 Stainless Steel Serrated Tooth Knurled Disc Spring Washer

Hexagonal slotted nuts are designed for use with DIN9250 Stainless Steel Serrated Tooth Knurled Disc Spring Washer with holes at the end of the screw, so that the split pin can be inserted into the hole of the screw from the slot of the nut to prevent the nut from loosening automatically. It is mainly used in occasions with vibration load or alternating load. .

The methods to prevent the automatic loosening of nuts (or bolts) in mechanical design and production are as follows:

1. Padded spring washer; (simple and easy to make)

2. Use hexagonal slotted nut + split pin; (increased processing procedures year-on-year)

3. Padded stop washer; (processing procedures added year-on-year)

4. Insert the steel wire into the hole of the hexagon head of the hexagon bolt. (Processing process increased year-on-year)

The main function of the DIN9250 Stainless Steel Serrated Tooth Knurled Disc Spring Washer is to protect the surface of the connecting piece from scratching the surface of the workpiece when the bolt and nut are tightened; the spring washer is anti-loosening. However, some important connections, such as the place where the power is transmitted by the friction force generated by compression, cannot be used with spring pads. If the rigidity of the connection is reduced, accidents are likely to occur. The spring washer can be omitted. 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. When there is vibration, pulse, and the temperature of the medium, it will be relatively large. When fluctuating, spring washers must be used. DIN9250 Stainless Steel Serrated Tooth Knurled Disc Spring Washer can increase the pre-tightening force and has the effect of preventing loosening, but the flat washer does not.
