Abstract

A fastening system, including a fastener including a threaded portion positioned on an outer surface of the fastener; a protrusion positioned on an outer surface of the fastener, the protrusion including a first angled surface; and an engagement surface; a nut corresponding to the fastener, including a threaded portion positioned on an inner surface of the nut; a first locking feature positioned on an inner surface of the nut, the first locking feature including a second angled surface; a first locking surface; a second locking feature positioned on the inner surface of the nut, the second locking feature including a third angled surface; a second locking surface.

First claim

What is claimed is:

1 . A fastening system, including:
a fastener including:
a threaded portion positioned on an outer surface of the fastener;
a protrusion positioned on an outer surface of the fastener, the protrusion including:
a first angled surface; and
an engagement surface;

a nut corresponding to the fastener, including:
a threaded portion positioned on an inner surface of the nut;
a first locking feature positioned on an inner surface of the nut, the first locking feature including:
a second angled surface;
a first locking surface;

a second locking feature positioned on the inner surface of the nut, the second locking feature including:
a third angled surface;
a second locking surface,

wherein, in a first state of engagement of the fastener with the nut, the first angled surface of the protrusion of the fastener engages with the second angled surface of the first locking feature of the nut to rotate the fastener with respect to the nut in response to a downward force on the fastener, and wherein in a second state of engagement of the fastener with the nut, a portion of the engagement surface of the protrusion is engaged with the second locking surface of the second locking feature to maintain a positioning of the fastener with respect to the nut.

2 . The fastening system of claim 1 , wherein a first slope of the first angled surface corresponds to a second slope of the second angled surface.

3 . The fastening system of claim 2 , wherein the first slope is complementary to the second slope.

4 . The fastening system of claim 1 , further including a spring and a washer.

5 . The fastening system of claim 4 , wherein the fastener is positioned through a through hole of a computing module such that the spring is positioned between a first surface of the computing module and a head of the fastener and the washer is positioned between a second surface of the computing module and the nut, the first surface of the computing module plate opposite to the second surface of the computing module.

6 . The fastening system of claim 5 , wherein the nut is coupled to a printed circuit board (PCB).

7 . The fastening system of claim 6 , wherein when the fastening system is in the second state of engagement of the fastener with the nut, the fastening system couples the computing module to the PCB.

8 . The fastening system of claim 7 , wherein the computing module is a heat sink.

9 . The fastening system of claim 4 , wherein the spring exerts a force against the head of the fastener such that the portion of the engagement surface is engaged with the second locking surface of the second locking feature to maintain the positioning of the fastener with respect to the nut.

10 . The fastening system of claim 1 , wherein the fastener further includes an additional protrusion positioned on the outer surface of the fastener, the additional protrusion including:
a fourth angled surface; and an additional engagement surface.

11 . The fastening system of claim 10 , wherein the nut further includes a third locking feature positioned on the inner surface of the nut, the third locking feature including:
a fifth angled surface; and a third locking surface.

12 . The fastening system of claim 11 ,
wherein, in the first state of engagement of the fastener with the nut, the fourth angled surface of the additional protrusion of the fastener engages with the fifth angled surface of the third locking feature of the nut to rotate the fastener with respect to the nut in response to the downward force on the fastener, and wherein in the second state of engagement of the fastener with the nut, a portion of the additional engagement surface of the additional protrusion is engaged with the first locking surface of the first locking feature to maintain the positioning of the fastener with respect to the nut.

13 . The fastening system of claim 12 , wherein a third slope of the fourth angled surface corresponds to a fourth slope of the fifth angled surface.

14 . An information handling system, including:
a processor; memory media storing instructions executable by the processor to perform operations; a fastening system, including:
a fastener including:
a threaded portion positioned on an outer surface of the fastener;
a protrusion positioned on the outer surface of the fastener, the protrusion including:
engagement surface;
a first angled surface; and

a nut corresponding to the fastener, including:
a threaded portion positioned on an inner surface of the nut;
a first locking feature positioned on the inner surface of the nut, the first locking feature including:
a second angled surface;
a first locking surface;

a second locking feature positioned on the inner surface of the nut, the second locking feature including:
a third angled surface;
a second locking surface,

wherein, in a first state of engagement of the fastener with the nut, the first angled surface of the protrusion of the fastener engages with the second angled surface of the first locking feature of the nut to rotate the fastener with respect to the nut in response to a downward force on the fastener, and wherein in a second state of engagement of the fastener with the nut, a portion of the engagement surface of the protrusion is engaged with the second locking surface of the second locking feature to maintain a positioning of the fastener with respect to the nut.

15 . The information handling system of claim 14 , wherein a first slope of the first angled surface corresponds to a second slope of the second angled surface.

16 . The information handling system of claim 15 , wherein the first slope is complementary to the second slope.

17 . The information handling system of claim 14 , the fastening system further including a spring and a washer.

18 . The information handling system of claim 17 , wherein the fastener is positioned through a through hole of a computing module such that the spring is positioned between a first surface of the computing module and a head of the fastener and the washer is positioned between a second surface of the computing module and the nut, the first surface of the computing module plate opposite to the second surface of the computing module.

19 . The information handling system of claim 18 , wherein the nut is coupled to a printed circuit board (PCB).

20 . A fastening system, including:
a plurality of fasteners, each fastener including:
a threaded portion positioned on an outer surface of the fastener;
a protrusion positioned on the outer surface of the fastener, the protrusion including:
a first angled surface; and
an engagement surface;
