A fastener comprising a pin and a collar. The pin comprising a shank comprising a tapered lock groove thread profile; and a head portion configured to receive a torque. The collar configured to be deformed onto and secured to the shank, wherein the collar comprises an external surface configured to receive a torque such that the collar can be removed from the shank after deformation.

A screw-latching assembly is provided. The assembly includes a screw with a head, a tip, and a body between the head and tip. The body includes a threaded portion adjacent to the tip and an unthreaded portion adjacent to the head, and the unthreaded portion includes a built-in collar with an outer diameter larger than that of the body. The assembly includes a supporting bracket supporting and partially encompassing a first portion of the screw. The supporting bracket includes a base and multiple sidewalls, with a first sidewall comprising a first opening to allow a second portion of the screw to extend out of the supporting bracket and a second sidewall comprising a second opening to allow access to the head by a torquing tool. The assembly includes a spring surrounding at least a portion of the body, with the spring positioned between the built-in collar and the first sidewall.

A pin for a coupler assembly for rotatably coupling a beam of a circle assembly of a grader machine with a bracket of a moldboard assembly of the grader machine includes a body defining a head portion and a shank portion. The shank portion integrally extends from the head portion. The head portion is adapted to be seated over one or more of the beam and the bracket. The shank portion is adapted to pass through the beam and the bracket to rotatably couple the beam and the bracket about the shank portion. A grease gallery is defined through the head portion, extending into the shank portion. The body defines multiple grease passages branching out from the grease gallery up to corresponding sections of an outer surface of the shank portion where the beam and the bracket are correspondingly adapted to lie in rotatable registration with the shank portion.

A fastening bolt fixes a plurality of stacked plates on each of which a hydraulic integrated circuit for hydraulically controlling an automatic transmission or a continuously variable transmission is formed. The fastening bolt includes a communication passage that communicates between the hydraulic integrated circuits among the plurality of plates.

Methods and devices for providing a threaded male member for a fastening arrangement are disclosed. The threaded male member can include at least one reaction portion at or towards at least one respective end of the threaded male member for use in reacting applied torque during tightening or releasing an associated nut of the fastening arrangement. The at least one reaction portion can be a permanent feature of the threaded male member and can remain part of the threaded male member after said tightening to a target torque.

A bolt for joining a first component and a second component, the bolt being capable of correcting a position of the second component with respect to the first component is provided. A bolt is fitted in a first hole of a first component and in a second hole of a second component in order to join the first component and the second component. The bolt includes a flange part, a threaded part, a head part, and a centering part. The centering part has a centering part body, and a plurality of blades. Each blade has an external-diameter increase portion in which a distance from the axis to an outer edge gradually increases toward a direction opposite to a tightening rotation direction of the bolt, and a distance from the axis to the outer edge gradually increases along an axial direction toward the flange part.

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.

A fastener structure includes a fastener having a stem portion and at least one movement portion. The stem portion has a fastening section. The movement portion is formed on the stem portion and has a retaining section. With these arrangements, the retaining section of the movement portion can be detachably assembled to a first object and the fastening section can be then detachably assembled or fastened to a second object. In this way, at least two objects can be connected to and disconnected from one another in a quick and repeatable manner.
