A ratchet fitting includes a screw portion and an operating portion. One of the screw portion and the operating portion has an engaging member, and the other one of the screw portion and the operating portion has an elastic member and a holding member formed separately from the elastic member. The elastic member and the engaging member are fitted such that a rotational force is transmittable to each other due to engagement of the projection and the protrusion and engagement between the projection and the protrusion is releasable due to deformation of the elastic member. The elastic member has a first fitting portion, the holding member has a second fitting portion, and the holding member and the elastic member are fitted such that the first fitting portion and the second fitting portion are fitted to each other in a rotation direction.

An interference fit joining method includes providing a tolerance adjuster and a die casting boss formed in a magnesium-based die casting. The method also includes positioning the tolerance adjuster over a cavity of the die casting boss. The method also includes pressing the tolerance adjuster at least partially into the cavity to form a joint assembly.

Various embodiments provide a post-to-beam fastener including a head, a tip, and a threaded shank connected to the head at a first end and the tip and a second end. In various embodiments, threaded shank includes a longitudinal axis extending from the head to the tip, and the tip includes a recess operable to removably receive a drill bit to the fastener.

A fitting includes a screw portion that is rotatable around an axis extending in one direction, an operating portion that applies a torque around the axis to the screw portion, and a rotation auxiliary member that is configured to be engageable with the operating portion. A slot extending from a first end to a second end is provided in the rotation auxiliary member, and also a first projection that protrudes outward is provided on the rotation auxiliary member. A positional relationship of the first projection is set such that an engaging force between the rotation auxiliary member and the operating portion is increased due to a change in width of the slot in a case where a force is applied to the first projection in the first rotation direction with the rotation auxiliary member engaging with the operating portion.

A collar for use on a water filtration tank adapter. The collar is formed as a ring adapted to thread onto the tank connection end of the adapter and abut the nut portion between the tank connection end and the pipe end of adapter. An o-ring, square in cross-section, is disposed on a top surface of the collar, offset medially towards the center. This top o-ring is adapted to abut the nut portion of the adapter. Another o-ring, square in cross-section, is disposed on the bottom surface, offset medially away from the center. This bottom o-ring is adapted to abut the tank head upon use. Accordingly, a water-tight seal is formed at the tank connection end and tank head, the collar functioning as both a positive stop and as a substitute for pipe tape.

Methods, systems, devices, and products for use in a pole support system. Apparatus include a hinge joint comprising: a base having an insertion end with a longitudinal slot and with a fulcrum protrusion on an inner surface; a cup having a receiving end selectively receiving the insertion end of the base; a securing assembly configured to selectively release the cup from the base, the securing assembly comprising a rotatable shaft that translates along the longitudinal slot between at least i) a lower relative position corresponding to an engaged state in which the insertion end is received by the receiving end, and ii) an upper relative position corresponding to a released state in which the insertion end is free of the receiving end; the shaft having a cam projection positioned to contact against the fulcrum protrusion and displace the shaft toward the upper relative position when the shaft is rotated.

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 solenoid assembly (100) is provided that includes a frame (104), a coil (106) positioned proximate the frame (104), and a core (114) defined by the coil (106). A plunger (108) is actuatable between at least a first position and a second position, and a guide (109) is at least partially disposed within the core (114). The plunger (108) is disposed at least partially within the guide (109). A housing (102) at least partially houses the frame (104), the coil (106), the guide (109) and the plunger (108), and the guide (109) is prevented from rotating independently of the housing (102).

A remote controller includes a remote controller body, a control stick provided on the remote controller body, and a bracket mounted on the remote controller body. The bracket includes a connecting frame and a holding mechanism. The holding mechanism includes a first clamping member rotatably connected to the connecting frame and including a first clamping part, and a second clamping member comprising a second clamping part and a limiting part. The second clamping member is slidably mounted on the first clamping member and configured to adjust a spacing between the second clamping part and the first clamping part. The holding mechanism further includes a limiter provided on the first clamping member. The limiter is fitted with the limiting part and configured to limit a relative sliding position of the first and second clamping members.
