Spring gasket is used to prevent loosening, such as the motor and the seat connected bolt generally to add spring pad, because the motor vibration if there is no spring pad, the nut will be loose generally with vibration on the equipment on the fastener equipped with spring gasket
Other classifications:
Inner tooth elastic gasket, outer tooth elastic gasket: has a lot of sharp elastic warping teeth on the circumference, thorn pressure on the support surface, can prevent the loosening of the fasteners. The inner tooth elastic gasket is used under the screw head where the head is small in size; the outer tooth elastic gasket is mostly used under the bolt head and nut. The elastic gasket with teeth is smaller than the ordinary spring gasket, with uniform force and reliable force to prevent loosening, but it should not be used for regular disassembly.
