Abstract
A deformable fastening system includes a clamped component and a fastener including a bolt having a shaft portion extending along a longitudinal axis of the fastener and a head portion having a surface including at least one engagement portion and one or more projections formed on the at least one engagement portion. The one or more projections are formed on the at least one engagement portion generally proximate the shaft portion. The one or more projections formed on the at least one engagement portion engage a mating surface of the clamped component to clamp the clamped component when the bolt is moved into a nut member causing an increase in axial load during the tightening cycle to deform the clamped component.
