The M6 safety washers made of A2 stainless steel, the shape S/DIN 53070 are locking elements shaped similar to a plate spring. The locking washers are serrated on both sides. They have an oblique serration on the top and bottom. Placed under the screw head or under the nut, the force is distributed over a larger area and protects the surface of the component. The power connection is optimised. By embossing the helical teeth into the mating support, a reliable positive fit is created. The locking washers form S/DIN 53070, are used where loosening of a screw connection is undesirable due to vibrations. Depending on the application, in addition to the pretensioning force, the securing of the connection against automatic loosening must be considered. Quantity:10pcs
