Flat Washers (Thru Hardened)

Click image to enlarge
Fasteners Etc., Inc. offers medium carbon steel flat washers (thru hardened) in both USS and SAE standards, in a variety of finishes for all your project needs. Flat washers are versatile in material and composition with different finishes or plating options as well. Those thru hardened flat washers may also be referred to as grade 8 in the field.

 A flat washer is simply a circular piece of metal that is primarily used for load distribution for assembly applications. The threaded fastener, or bolt, will be inserted through the center of the flat washer so that it rests between the underside head of the bolt and the connecting material. The additional surface area reduces stress and helps prevent damage or pull through. Flat washer sizing is often called out by the bolt size so if you are using a ½” diameter bolt, you will need a ½” diameter flat washer as well. This is also known as the internal diameter which is universal between standards.
 
If your project requires USA or Domestic manufactured flat washers (thru hardened) we can certainly provide you the material and certifications, no additional costs required. We carry standard sizes and metric sizes available in USA/Domestic.
