(71) Series AI pre-stressed disc springs are used to maintain load or tension in bolted assemblies. Pressure begins at the outer radius and flattens gradually towards the bolt as deflection progresses. Disc springs exert a uniform pressure that remains constant despite tension losses caused by thermal expainsion and contraction, compression set or wear of parts. Because pressures are predictable, disc springs provide a simple and effective means of determining bolt tension that is far more accurate than "torque" readings.
