Hardened Flat washers are used under bolt heads or nuts to increase the bearing area and to offer hardness so that the nut or bolt can be rotated without distortion of the bearing surface. For the construction market, there is a range of hardened washers to both BS EN14399-6/9 and 15048.
Washers provide a smooth bearing surface and are used under the head of a bolt and / or a nut. These washers are through hardened or carburized to add strength, but are physically smaller than a standard F844 flat washer. They are the recommended washer for any fastener other than a low carbon steel bolt.
Application : Hardened Flat washers are used under bolt heads or nuts to increase the bearing area and to offer hardness so that the nut or bolt can be rotated without distortion of the bearing surface.
Types : These types of washers can also be used with other fasteners such as... Washer hardness
