Patent abstract
A preload indicating washer assembly that operates in the elastic region for a rated compression is disclosed. Because it operates in the elastic region, the preload indicating washer assembly resumes its original shape when the compression is decreased or removed. The washer assembly elastically deforms again to the same extent as its original deformation when the predetermined compression is restored. Thus the washer assembly will indicate the proper fastener preload when used for multiple loading cycles or in multiple locations.
