摘要： A multi-piece locking fastener having an intermediate component exhibiting a plurality of interior threads arrayed in a first direction. A first fastener has a first enlarged head and a first stem exteriorly threaded in the first direction. A hollowed interior is formed in an end of the stem and exhibits a further plurality of interior threads extending in a second direction opposite the first direction. A second fastener has a second enlarged head and a second stem, upon which is configured a second exterior thread pattern extending in the second direction. The first fastener is installed through the intermediate component from a first direction, with the second fastener rotationally inter-engaging the exposed interior threads of the first fastener in the second direction until the second enlarged heads contact the intermediate component, with loosening of either of the first and second fasteners being prevented.

摘要： A multi-piece locking fastener assembly including a thickened base layer having a first wider diameter passageway exhibiting a first interiorly threaded orientation and a second narrower diameter passageway exhibiting a second opposite threaded orientation and extending a distance in communication with and beyond a bottom end wall of the first wider passageway. A first bolt fastener has a first arrangement of exterior threads engageable with the wider diameter passageway of the base layer. The first fastener further includes an interior passageway. Following installation of the wider fastener into the base layer, a second narrower diameter bolt fastener having at least a partially threaded stem is threadably inter-engaged with the second passageway in the base layer to prevent loosening of either fastener via their counter-threaded orientations.

摘要： A three-piece locking fastener including an interiorly threaded intermediate component open at opposite ends. A first screw having a first exterior thread pattern rotationally inter-engages with the interior threads of the intermediate component when installed through a first selected one of the opposite ends, the first screw having a hollow shaft exhibiting a further plurality of interior threads matching a direction of the first thread pattern. A second screw has a second exterior thread pattern opposite the first pattern and, upon being installed within the other selected one of the opposite ends, rotationally inter-engages the interior threads of the first screw, so that loosening of either of the first and second screws being prevented by their counter-threaded orientation.

摘要： A fastener assembly having a nut with interior threads extending from a first end to an intermediate end wall, a narrowed diameter aperture extending from the end wall toward a second end. A first screw has a shaft exhibiting a first exterior thread pattern rotationally inter-engaging with the interior threads of the nut when installed through the first end. A recess formed in an end of the shaft exhibiting a further plurality of interior threads matching a direction of the first thread pattern. A second screw has a second exterior thread pattern opposite the first pattern and, upon being installed through the narrowed aperture, rotationally inter-engaging the interior threads of the first screw, with loosening of either screw being prevented by their counter-threaded orientation. A head of the second screw exhibiting an outer annular rim establishing a resistance fit within an entranceway location of the nut.
