Boker’s is a leading stamping manufacturer of D-washers.

D-washers get their name based on the “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.

Many applications require D-washers and they are used in many industries such as automotive, marine, aerospace, medical and countless more. D-washers, also referred to as clipped washers, are generally used in applications where space limitations do not allow the use of a flat round washer and/or when keeping an assembly stationary is required.
