Abstract
The present invention relates to a fastener, such as a bolt or a nut, for fastening a wheel to a vehicle, comprising: a body comprising: a cap receiving portion, a threaded portion and a central axis; and a cap, arranged to be received by and cover said cap receiving portion characterized in that said cap receiving portion comprises a recess or a protrusion against which said cap can be deformed, or has been deformed, such that said cap forms a mutual matching protrusion or recess, wherein said recess or protrusion of said cap receiving portion has a longitudinal extension essentially parallel to said central axis. The present invention also relates to a method for assembling a fastener.
Claims13
A fastener for fastening a wheel to a vehicle, comprising:
- a body comprising:
- a cap receiving portion, a threaded portion and a central axis, wherein said cap receiving portion has a hexagonal cross-section, in a plane perpendicular to said central axis, and six side surfaces and six edges each having a longitudinal extension parallel to said central axis;
- and
- a cap, arranged to be received by and cover said cap receiving portion,
- wherein said cap receiving portion comprises a recess against which said cap can be deformed, or has been deformed, such that said cap forms a mutual matching protrusion,
- wherein said recess of said cap receiving portion has a longitudinal extension essentially parallel to said central axis,
- wherein said recess is provided in a side surface of said six side surfaces, between two of said six edges,
- wherein said recess of said cap receiving portion comprises a groove having a longitudinal extension parallel to said central axis and an end stop, said end stop arranged adjacent a trailing surface of said body of said fastener, and wherein the end stop is a protrusion formed in the groove, and wherein the longitudinal extension of the recess is greater than its width.
A method of assembling a fastener, said fastener comprising:
- a body comprising:
- a cap receiving portion, a threaded portion, a central axis, wherein said cap receiving portion has a hexagonal cross-section, in a plane perpendicular to said central axis, and six side surfaces and six edges each having a longitudinal extension parallel to said central axis;
- and
- a cap,
- said method of assembling said fastener comprising the steps of:
- capping said body, by arranging said cap to said cap receiving portion, such that said cap covers said body, and
- deforming said cap such that said cap forms a protrusion, when the cap receiving portion comprises a recess, so that said formed protrusion matches said recess of said cap receiving portion,
- wherein said recess of said cap receiving portion has a longitudinal extension parallel to said central axis,
- wherein said recess is provided in a side surface of said six side surfaces, between two of said six edges,
- wherein said recess of said cap receiving portion comprises a groove having a longitudinal extension parallel to said central axis and an end stop, said end stop arranged adjacent a trailing surface of said body of said fastener,
- wherein the end stop is a protrusion formed in the groove, and
- wherein the longitudinal extension of the recess is greater than its width.
