GB93-76,spring washer, high strength spring washer, oxidation black, carbon steel 300HV
1. Product Description
The spring washer is easy to use, with higher usability, high strength, firmness and durability, corrosion resistance and not easy to rust
The washer head is flat, the force is even and the fastening effect is good, the glossiness is high and the appearance is beautiful.
Spring washer is widely used in the bearing and non bearing structures of general mechanical products, which is characterized by low cost, convenient installation and suitable for the parts with frequent assembly and disassembly. But the spring washer's anti loose ability is very low! Especially in the European and American countries, the adoption rate of high reliability products is very low, especially the important bearing structure connection parts have been abandoned for many years.

3. Application
The spring washer is installed under the nut to prevent the nut from loosening.
It is stated in national standards.
Hexagonal slotted nut is designed for use with bolts with holes at the end of the screw, so that the opening 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 situations with vibration load or alternating load.
The methods of preventing nut (or bolt) from loosening automatically in mechanical design and manufacture are as follows:
1. Padded spring washer; (Easy to do)
2. Hexagonal grooved nut + open pin; (Processing process increased year-on-year)
3. Padded stop gasket; (year-on-year increase in processing procedures)
4. The hexagonal head opening of the hexagonal bolt is inserted into the steel wire. (Processing procedures increased year-on-year)
