These Double Retaining Washers enable secure assembly of standard screws, bolts and nuts. Once in place, these Washers press into the threads of bolt and nut resulting in effective multiple locking and sealing, which prevents leakages. Easy to fit, these Washers prevent the nut from loosening on the assembly, dampen vibration and noise, and prevent electrolytic corrosion between two different metal surfaces. Excellent chemical resistance to oil and petrol allows these Washers to be used in many difficult working environments.
