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.
Claims22
A deformable fastening system comprising:
- a clamped component;
- and
- a fastener including a bolt having a shaft portion extending along a longitudinal axis of the fastener, the shaft portion including a securing portion formed thereon, and a head portion having a surface including at least one engagement portion,
- wherein the shaft portion of the bolt is inserted through a passage in the clamped component to engage a corresponding thread on a nut member and the head portion of the bolt is rotated to move the bolt into the nut member during a tightening cycle,
- wherein the at least one engagement portion includes one or more projections formed on the surface of the head portion generally proximate the shaft portion and in arrangement with the longitudinal axis and shaft portion,
- wherein the one or more projections includes at least one first projection extending generally circumferentially about the surface of the head portion relative to the longitudinal axis and one or more second projections extend generally circumferentially about the surface of the head portion relative to the longitudinal axis,
- wherein the at least one first projection is formed with at least one geometric profile with multiple arcuate shaped engagement surfaces as part of the surface of the head portion to provide a sealing arrangement between the fastener and a mating surface of the clamped component,
- wherein the one or more second projections are disposed radially inward from the at least one first projection and are formed with at least one geometric profile to provide a grounding arrangement with the mating surface of the clamped component,
- wherein the one or more projections formed on the at least one engagement portion of the surface of the head of the bolt engage the mating surface of the clamped component when the bolt is moved into the nut member causing an increase in axial load during the tightening cycle to deform the clamped component.
A fastener comprising:
- a bolt having a head portion and a shaft portion extending along a longitudinal axis of the fastener, the shaft portion including a securing portion formed thereon;
- and
- at least one engagement portion formed on a surface of the head portion, wherein the at least one engagement portion includes one or more projections formed on the surface of the head portion generally proximate the shaft portion and in arrangement with the longitudinal axis and shaft portion,
- wherein the one or more projections includes at least one first projection extending generally circumferentially about the surface of the head portion relative to the longitudinal axis,
- wherein the at least one first projection is formed with multiple arcuate shaped engagement surfaces as part of the surface of the head portion,
- wherein the multiple arcuate shaped engagement surfaces are formed on the at least one first projection in offset positions to engage a clamped component at various distinct engagement depths to provide a sealing arrangement between the fastener and the clamped component.
A fastener comprising:
- a bolt having a head portion and a shaft portion extending along a longitudinal axis of the fastener, the shaft portion including a securing portion formed thereon;
- and
- at least one engagement portion formed on a surface of the head portion, wherein the at least one engagement portion includes one or more projections formed on the surface of the head portion generally proximate the shaft portion and in arrangement with the longitudinal axis and shaft portion, wherein the one or more projections includes,
- at least one first projection extending generally circumferentially about the surface of the head portion relative to the longitudinal axis, wherein the at least one first projection is formed with multiple arcuate shaped engagement surfaces as part of the surface of the head portion, wherein the multiple arcuate shaped engagement surfaces are formed on the at least one first projection in offset positions to engage a clamped component at various distinct engagement depths to provide a sealing arrangement between the fastener and the clamped component, and
- one or more second projections extending generally circumferentially about the surface of the head portion relative to the longitudinal axis, the one or more second projections are formed as a plurality of discrete members cooperatively arranged to extend circumferentially around the surface of the head portion to provide a continuous engagement with the clamped component.
