Custom D-Washers Help Keep Things Together

Boker’s, a manufacturer of precision metal stampings, washers, spacers and shims, offers a wide array of application-specific D-washers. Based on a “D” shape that is created by having a flat edge on either the OD, the ID, or a combination of both, D-washers provide a flat bearing surface and are used under the head of a bolt and/or a nut to disperse loads as well as prevent the washer from turning in the application. They are generally mounted with the flat edge of the washer facing a flat surface or recessed hole.


D-washers are used in numerous industries such as automotive, marine, aerospace, medical, and countless more.  Boker’s maintains over 32,000 stock tools for flat round washers, spacers, and shims without tool charges. A wide variety of sizes, thicknesses, and materials, including non-metallic are available.  With outside diameters of 0.080" to 5.140" and a wide variety of inside diameters, millions of flat and specialty-washer designs are possible.
