Abstract
A faceted lobular threaded component and methods for making and/or installing the same. A faceted lobular threaded component may include a head, and a shank extending along a longitudinal axis away from the head. The component may also include an external faceted lobular thread in the shank extending around the longitudinal axis. The external faceted lobular thread may include at least four facets per thread revolution, and at least four lobes per thread revolution circumferentially interspersed between the at least four facets and established by the at least four facets.
Claims24
A faceted lobular threaded component, comprising:
- a head;
- a shank extending along a longitudinal axis away from the head;
- and
- an external faceted lobular thread in the shank extending around the longitudinal axis;
- wherein the external faceted lobular thread includes:
- at least four facets per thread revolution, and
- at least four lobes per thread revolution circumferentially interspersed between the at least four facets and established by the at least four facets,
- wherein the head has an internally threaded head passage, and wherein the shank extends from the head and includes:
- an internally threaded shank passage coaxial with the internally threaded head passage;
- and
- an end wall extending across the internally threaded shank passage with a vent hole therethrough in communication with the shank internal passage.
A faceted lobular threaded component, comprising:
- a head;
- and
- a shank extending from the head and including:
- a generally closed end having a vent hole;
- an internal threaded bore extending through the head to proximate the closed end and in communication with the vent hole;
- an external faceted lobular threaded portion defining an external thread, the external faceted lobular threaded portion defining at least four facets per thread revolution;
- an external unthreaded cylindrical portion between the threaded portion and the head;
- an anti-galvanic coating on the head and the external unthreaded cylindrical portion;
- and
- an adhesive coating covering an intermediate section of the threaded portion.
A faceted lobular threaded component, comprising:
- a head;
- a shank extending along a longitudinal axis away from the head;
- and
- an external faceted lobular thread in the shank extending around the longitudinal axis;
- wherein the external faceted lobular thread includes:
- at least four facets per thread revolution, wherein at least one facet of the at least four facets includes a thread tip facet and at least one thread flank facet, and
- at least four lobes per thread revolution circumferentially interspersed between the at least four facets and established by the at least four facets.
An assembly, comprising:
- an object having an unthreaded blind hole;
- and
- a faceted lobular threaded component threaded into the blind hole, comprising:
- a head,
- a shank extending along a longitudinal axis away from the head, and
- an external faceted lobular thread in the shank extending around the longitudinal axis and including:
- at least four facets per thread revolution, and
- at least four lobes per thread revolution circumferentially interspersed between the at least four facets and established by the at least four facets,
- an internal passage,
- a closed end, and
- a vent hole through the closed end.
