Abstract
A bolt includes a main-bolt head, a threaded shaft, and a deformable-bolt head component. The main-bolt head has a recess. The threaded shaft extends from the main-bolt head. The threaded shaft has an external thread wrapped therearound. The deformable-bolt head component has an outer flange and an interior threaded bore. The outer flange of the deformable-bolt head component is coupled to the main-bolt head such that a relief space is formed between the deformable-bolt head component and the recess.

A method of making a bolt, the method comprising:
- providing a main-bolt head with a threaded shaft extending therefrom, the main-bolt head having a recess;
- providing a deformable-bolt head component having an outer flange and an interior threaded bore;
- and
- threading the deformable-bolt head component onto the threaded shaft (i) such that a portion of the deformable-bolt head component is positioned within the recess of the main-bolt head and (ii) until the outer flange engages a front surface of the main-bolt head, thereby forming a relief space between the deformable-bolt head component and the recess.
A method of securing a bolt to an object with a nut, the bolt having a threaded shaft extending from a main-bolt head and a deformable-bolt head component coupled to the main-bolt head such that a relief space is formed between the main-bolt head and the deformable-bolt head component, the method comprising:
- positioning the threaded shaft through an opening in the object such that a portion of the threaded shaft protrudes from the opening;
- threading the nut onto the portion of the threaded bolt shaft protruding from the opening by rotating the nut in a first rotational direction, thereby causing the nut to move axially in a first direction towards a first surface of the object;
- causing a front surface of the nut to abut the first surface of the object and causing a front surface of the deformable-bolt head component to abut a second opposing surface of the object by:
- (i) continuing to thread the nut onto the portion of the threaded bolt shaft,
- (ii) rotating the bolt in a second opposing rotational direction, or
- (iii) a combination of (i) and (ii);
- with the front surface of the nut abutting the first surface of the object and with the front surface of the deformable-bolt head component abutting the second opposing surface of the object:
- (a) applying a first rotational torque in the first rotational direction to the nut,
- (b) applying a second rotational torque in the second rotational direction to the bolt, or
- (c) both (a) and (b),
- the application of the first rotational torque, the application of the second rotational torque, or the application of both the first and the second rotational torques causing:
- (x) the main-bolt head to move axially in a second direction that is opposite the first direction, and
- (y) the deformable-bolt head component to deform, thereby entering into the relief space formed between the deformable-bolt head component and the main-bolt head.
A method of making a bolt having a reinforced head, the method comprising:
- providing a main-bolt head with a threaded shaft extending therefrom;
- positioning an angled collar about the threaded shaft such that the angled collar engages the main-bolt head, the angled collar having an angled inner surface;
- fixing the angled collar to the main-bolt head, thereby forming a recess of the reinforced head;
- and
- threading a deformable-bolt head component onto the threaded shaft (i) such that a portion of the deformable-bolt head component is positioned within the recess of the reinforced head and (ii) until an outer flange of the deformable-bolt head component engages a front surface of the angled collar, thereby forming a relief space between the deformable-bolt head component and the recess.
