DIN 125 A Flat Washer

DIN 125 A Flat Washers, without chamfer, are a thin disk with a concentric hole and are one of the most popular flat washers. When placed under a nut or the head of a screw, the washer increases the bearing surface area and consequently distributes the clamping force over a larger area. That result is desirable when working with soft materials and holes that are too large or oddly shaped to properly support the screw head or nut. "Without chamfer" indicates that the outside edge on one side is not beveled. Steel in 140 HV, 200 HV and 300 HV, either zinc plated or plain finish (which lacks rust protection), and stainless steel can be supplied. Washers with a Hardness Class of 140 HV should only be used with bolts/screws below Class 8.8 and nuts below Class 8; 200 HV washers are suitable for Class 8.8/Class 8 and below; and use 300 HV washers for Class 10.9 bolts/screws and Class 10 nuts and below—they are not suitable for use with Class 12.9/Class 12 fasteners. Washers are listed by their nominal hole size, which indicates screw size, so if you have an M10 screw select an M10 washer. DIN 125 A Flat Washers may be the same as ISO 7089. DIN 433 is a smaller OD and DIN 9021 is a larger OD washer compared to DIN 125 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.
