An anti-vibration fastener, including a square flange bolt to affix a first object to a second object, the square flange bolt including a first threaded portion disposed at a front end of the square flange bolt, and a second threaded portion disposed at a rear end of the square flange bolt having a diameter smaller than a diameter of the first threaded portion, and a forward nut to encapsulate at least a portion of the square flange bolt such that the first object and the second object are disposed between the forward nut and the front end of the square flange bolt, and an aft nut to encapsulate at least a portion of the square flange bolt and the forward nut.

A fastener-retaining system (100) is configured to securely couple a fastener (102) to a substrate (104). The fastener-retaining system (100) includes a compression-limiting bushing (106) including a tube defining a central passage (132), and a retainer (130) positioned within the central passage. The retainer (130) includes a first portion that securely connects to the bushing, and a second portion that is configured to securely connect to a portion of the fastener.

An anti-vibration fastener, including a square flange bolt to affix a first object to a second object, the square flange bolt including a first threaded portion disposed at a front end of the square flange bolt, and a second threaded portion disposed at a rear end of the square flange bolt having a diameter smaller than a diameter of the first threaded portion, and a forward nut to encapsulate at least a portion of the square flange bolt such that the first object and the second object are disposed between the forward nut and the front end of the square flange bolt, and an aft nut to encapsulate at least a portion of the square flange bolt and the forward nut.

A dual sided fastener kit including at least one dual sided fastener member and at least one fastener head attachment. The at least one dual sided fastener member attaches a target object to a source object. The dual sided fastener member includes a first side and a second side separated by a middle disc element. The first side and the second side each include a fastener end for insertion into a target object or a source object. The at least one fastener head attachment member includes a hollow tube attached to a head disc element for aiding in the insertion of a fastener end into a target object or a source object. The fastener head attachment member covers a fastener end at either the first side or second side for aiding in the insertion of the fastener end which is located at an opposite end from the covered fastener end.

An apparatus for anchoring fasteners includes a shaft, a guide disk and a flange. The shaft extends in an axial direction between a proximal end and a distal end. The shaft has an internally threaded axial bore, and at least one outer surface thread. The guide disk is disposed at the distal end of, and coaxially with, the shaft. The first disk has a first diameter that is less than a major diameter of the at least one outer surface thread, and greater than a minor diameter of the at least one outer surface thread. The flange is disposed at the proximal end of the shaft, and has a width exceeding the first diameter. The flange includes a drive feature configured to engage a drive tool.

A quick release fastener. The quick release fastener comprises a first end, a second, opposing end, and a main body therebetween. The main body comprises an internal lumen or passageway having a plurality of guiding surfaces and securing surfaces. The securing surfaces are preferably angled surfaces. The angled orientation provides a securing member insertion axis (which also forms the longitudinal axis) and a securing member securing axis; each axis forming a separate plane to allow the quick release fastener to quickly and easily traverse between a locked position and an unlocked position.

A system of connecting a stiffener to the sidewall of a grain bin using a stud bolt having a first threaded end, a second threaded end and a feature positioned between the first end and a second end. A sealing member is positioned over the first end of the stud bolt, which in one case is a metallic washer with an affixed compressible sealing member. The first end of the stud bolt is inserted into a hole in the sidewall and an inner nut is placed over the first end inside the sidewall. As the inner nut is tightened, the feature is pulled toward the exterior surface of the grain bin thereby causing the sealing member to form a seal with the exterior surface of the grain bin. The second end of the stud bolt is inserted into a hole in the stiffener which is tightened onto the stud bolt.

Watertight fastening devices and systems and methods for the employment thereof are disclosed. The disclosed watertight fastening device includes a head, a shank extending away from the head toward a distal end, and a cover extending outwardly and away from the head in the direction of the shank and defining a hollow region between the shank and an inner surface of the cover. The watertight fastening device may be used in conjunction with a solar power installation system that includes a base plate configured to be positioned against an installation surface. The base plate includes an aperture for receiving the shank of the fastener and protrusion surrounding the aperture configured to be received in the hollow region of the fastener, thereby providing an enhanced barrier against moisture reaching the installation surface.

A motor vehicle fastening system for fastening a first motor vehicle component to a second motor vehicle component by a fastening device is provided. The fastening device includes a bolt element, a screw-on element and a tolerance element. The bolt element is connected to the second motor vehicle component in a rotationally fixed manner by screwing the bolt element into the second motor vehicle component up to a contact surface formed on the bolt element. The tolerance element is screwed onto the bolt element and also is supported against the first motor vehicle component such that the tolerance element can be moved relative to the first motor vehicle component along a first axis and a second axis. A screw-on element is arranged on a side surface of the first motor vehicle component facing away from the second motor vehicle component and is screwed onto the bolt element. A spacing element is arranged between the first motor vehicle component and the second motor vehicle component such that the spacing element arranges the first motor vehicle component at a predefined distance from the second motor vehicle component when the screw-on element loads the first motor vehicle component against the second motor vehicle component via the spacing element.

An assembly for receiving a fluid subjected to fluctuating pressure has a housing with at least two housing parts. A tensioning bolt connects the at least two housing parts to each other. The tensioning bolt has at least two spaced-apart threaded sections, wherein the at least two threaded sections each are screwed into a respective counter thread in the at least two housing parts. The assembly can be a suction pipe or an air filter device of an internal combustion engine.
