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.

A device for adjusting the height of a motor vehicle body (3), including an actuator (1) for actuating a vertically adjustable spring seat of a suspension spring (15), characterized in that a pin (4) is provided for connecting the device to the vehicle body (3), an actuator side pin section (10) extends through a support eye (6) in a support plate (7) of the actuator (1), and an elastomer support (2) is disposed at least on the face of the support plate (7) facing the vehicle body, between the support plate (7) and a flange (9) provided on the bolt (4).

Tension-controlled U-bolts are disclosed having a curved rod with first and second threaded arms extending therefrom. A shearable spline is provided at the end of at least one of the threaded arms. An annular recessed channel is provided between the shearable spline and the threaded arm that provides a shear zone when a predetermined amount of torque is applied to the shearable spline.

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.

A drainage bolt having a top and a bottom, a head at the top, and a main shaft extending from the head to the bottom. The head has a flange having a top surface with a central opening. The main shaft has a threaded portion near the bottom, and a bottom opening. A drainage channel extends from the central opening to the bottom opening. Two surfaces may be joined together by the drainage bolt such that the flange rests against one of the two surfaces and a nut is tightened onto the threaded portion of the main shaft against the other of the two surfaces. Water collecting above one of the two surfaces enters the drainage channel at the central opening and exits from the bottom opening.

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.

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.

Provided is a wind turbine with a nacelle including a mounting structure to which at least one facing element is attached and/or with a hub including a mounting structure to which at least one facing element is attached, which at least one facing element is attached with several fixation devices, whereby each fixation device includes a bolt with a bolt head at one end, a threaded shaft extending through an opening in the facing element and the mounting structure and a tool mount for attaching a tool for holding the bolt, and a nut screwed on the threaded shaft, with the bolt head positioned at the outside of the nacelle or the hub and the tool mount and nut positioned at the inside of the nacelle or the hub.

A fastening assembly includes a fastening member and an operating member movably sheathed on the fastening member. The fastening member includes a threaded part and a mating part connected to the threaded part. The operating member includes a snap-fitting part corresponding to the mating part.
