FEATURES

DIN 6798 J Internal Serrated Lock Washers have twisted tabs that create serrations around the inside circumference of the washer and contact the bearing surface of the screw or nut and the mating surface. Recommended for use with small diameter heads, like cheese head, and when the prongs and surface marks they create should be hidden but avoid oversized holes because the prongs may not fully contact the mating surface. Supplied in spring steel with a phosphate finish and zinc plated and in stainless steel. Select the washer size, which is its nominal hole size, to match the screw size (for example, an M8 washer matches an M8 screw). They may be specified as DIN 6798 Type J.
