DIN 6798 A External Serrated Lock Washers

DIN 6798 A External Serrated Lock Washer

DIN 6798 A External Serrated Lock Washers rely upon serrations, formed from twisted tabs around the washer's outside circumference, to resist loosening. To ensure the prongs contact the head and mating surface, use with large diameter heads like pan. Having the prongs around the perimeter provides greater twisting resistance. Spring steel with a phosphate finish and zinc plated, and stainless steel are available. Washer size indicates nominal size and should be selected to match the screw size (M6 washers are used with M6 screws for instance). They are sometimes referred to as DIN 6798 Type A.

Product Filter Help

It's easy and fast to find the exact item you're looking for using these filters. Depending on the item, you can filter by Size (diameter and thread), Length, Grade/Class, Material and Finish/Plating. Here's how…

  • Click in a Select box to view the options. It may be necessary to scroll to see the entire list. The number of matching items is displayed in parentheses ( ).
  • Click on the desired item and -- Select -- will change to 1 Selected. You can select more than one item in each Select box. For example, you can select two sizes and 1 Selected will change to 2 Selected.
  • Click in other Select boxes and make more choices. Available options will be based on selections you've already made.
  • Even though there are thousands of fasteners to choose from a particular material or finish may not be available in every size and length. So, try different combinations of filters like Size, Grade and Material to see matching Lengths and Finishes.
  • To deselect a single filter option, click in the Select box and click on the selected option. It will appear at the top of the list in bold. To clear all filter selections, click on the Clear Filters button.

Even after filtering there may be several pages of items. The number of pages will be displayed to the left of the Add All Selected Items button. Click on a page number or the arrows to page forward and back.
