適用范圍：This standard specifies the characteristics of heat resisting steel, countersunk, load spreading washers for usein aerospace applications at temperatures not exceeding 650 ℃.They are intended primarily for use under the head of bolts with strength classification up to 1 250 MPa. Theyare used to provide sufficient bearing area to prevent indentation of parent metals with low compressivestrength at operating temperatures, thus ensuring no relaxation in the bolt load occurs.
