摘要：
A load indicating washer, or tension washer, for visually indicating pre-determined magnitudes of tension force in a tension tie member. The tension washer comprises a body portion with a deformable, curved annular flange member depending from the body portion. When the tension washer is compressed against a flat bearing surface, the flange member deforms to produce a visual or color indication of the magnitude of load in the tie member.
