An aircraft monument floor attachment stud may include a body configured to pass through an opening of an aircraft monument, and a head. The body may include a body diameter. The body may be configured to couple to a fitting inserted into a mount point installed within an aircraft cabin floor. The head may include a tool section with a tool section diameter less than the body diameter. The tool section may be configured to receive a predetermined amount of torque from a tool to secure the aircraft monument to the fitting. The head may include a shaped section with an intermediate diameter greater than the tool section diameter and less than the body diameter. The shaped section may include at least one shaped portion with at least one sloped wall, and may be configured to provide a transition between the tool section diameter and the body diameter.

A bolt comprises a first shank segment axially comprising an externally threaded segment at a proximate axial end of the bolt. The bolt also includes a second shank segment, a flange extending perpendicularly a first distance from the first shank segment and axially located between a distal axial end of the first shank segment and a proximate axial end of the second shank segment, and a head axially adjacent to a distal axial end of the second shank segment, where the head is longer than the flange in a first direction perpendicular to the first shank segment but shorter than the flange in a second direction perpendicular to the first shank segment.

The present invention relates to a press-fit nut for an assembly, a press-fit nut-bolt assembly, and a method of constructing a steel-concrete composite structure using same, wherein a process is simple and a base material does not become deformed during an installation process. The press-fit nut-bolt assembly of the present invention includes a press-fit nut, a stud bolt, a counter nut, and a washer. The press-fit nut includes: a head part formed in a typical nut shape; and a press-fitting part that is formed extending from one of the two surfaces of the head part so as to have an outer diameter less than that of the head part, and that is inserted, through press-fitting, into a base material (M) that is an object requiring fastening. A hollow having threads is continuously formed in the head part and the press-fitting part. The stud bolt includes a body part that is coupled to the press-fit nut by passing therethrough, and a pin tail which is formed extending from an end of the body part and to which a mechanism for rotating the body part is coupled. The body part includes a first threaded portion and a second threaded portion which are formed on the outer surface of the body part along the lengthwise direction of the body part and spaced apart from each other.

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 disclosed tolerance compensator system reduces or avoids bending of components when the components are fastened to each other, thereby increasing the reliability of the components. The limited number of parts of the tolerance compensator system simplifies manufacturing and reduces costs. A disclosed method for fastening components together using the tolerance compensator system reduces or avoids bending of components, increases the reliability of the components, reduces fastening times, and simplifies fastening procedures.

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 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, a first sheathing hole, and a second sheathing hole. The first sheathing hole and the second sheathing hole are arranged along the axial direction of the operating member. The first sheathing hole and the second sheathing hole are in communication with each other and together penetrating the entire operating member. A size of the first sheathing hole is smaller than a size of the second sheathing hole. A stepped surface is formed at a position where the first sheathing hole and the second sheathing hole are connected.

A mounting device for a mounting member is disclosed. The mounting device comprises a first flange configured to be fitted under a mounting surface, a second flange configured to be inserted in the first flange. Further, the second flange having a first section that is configured to provide an orifice for inserting the mounting member, a second section having a plurality of threads for receiving the first flange, a third section having a plurality of threads, and a fourth section having a plurality of threads. Further, a compression nut, having an inner surface, is configured to pass over the mounting member and tightened on the fourth section of the second flange over the plurality of threads. Thereafter, a ring is configured to be fitted over the mounting member and between the fourth section of the second flange and the compression nut.
