A tool for removal of a spring clip from a nut plate assembly includes an inner sleeve having a first cleat configured to engage a first end of a spring clip and an outer sleeve having a second cleat configured to engage a second end of the spring clip, the outer sleeve being rotatably disposed around a portion of the inner sleeve. The tool includes first and second grip tabs respectively extending radially from a longitudinally extending central axis of the inner sleeve and the outer sleeve. Movement of the first grip tab and the second grip tab towards each other rotates the inner sleeve relative to the outer sleeve, and causes the first cleat and the second cleat to rotate towards each other to engage the first and second ends of the spring clip and to enable the spring clip to be removed from an assembled nut plate.

A connecting assembly includes: a connecting pipe, an inner wall of at least one end of the connecting pipe being provided with a pre-embedded nut, and the nut being coaxial with the connecting pipe; a connecting plate, the connecting plate being provided with a fixing hole; and a fastener, the fastener penetrating through the fixing hole and being in threaded fit with the nut. The connecting pipe is a light alloy component, and the connecting plate is a steel component. The connecting pipe is the light alloy component, the inner wall of at least one end of the connecting pipe is provided with the pre-embedded nut, and the fastener sequentially penetrates through the fixing hole on the connecting plate of a steel material and is in threaded fit with the nut at one end of the connecting pipe.

A sheet metal nut includes a base having a flat planar surface. The sheet metal nut also has a sleeve that extends below the base and includes an inner surface. The sheet metal nut further includes at least two front flanges and at least one rear flange. The at least two front flanges are positioned on an edge of the base and extend to a position directly above the flat planar surface of the base. The at least one rear flange extends away from a rear surface of the base. The sheet metal nut is configured to securely fasten to a bottom side of a component through a single aperture when the bottom side of the component is restricted or inaccessible.

Screwing into wood with any sized screw can result in the wood becoming split. The wood can be pre-drilled to reduce the risk of splitting; however, if the pre-drilled hole is too small the wood is still relatively likely to split, whereas if the hole is too big the retaining force of the screw may be reduced significantly. The present invention provides an attachment apparatus for enabling a bolt to be secured to substrate that is susceptible to fracturing, the apparatus comprising: a plate 41 with a plurality of openings 42 therethrough, wherein each opening 42 is configured to receive a fixing member, and wherein the plate 41 includes a plate orifice 43 therethrough; and a receiving member 44 fixedly secured to the plate 41, the receiving member 44 having a cavity with an aperture 45 at one end that at least partially overlaps the plate orifice 43, wherein the receiving member 44 is configured to receive and retain a corresponding bolt such that the corresponding bolt is also disposed within the aperture 45, cavity and the plate orifice 43. In this way, the risk of fracturing a substrate susceptible to fracturing is reduced when securing a bolt thereto.

A tolerance compensation device includes a base device having a tubular fastening portion that includes an internal, right-hand thread for receiving a screw-like fastening element. A tubular connecting portion, for connecting to a compensation structure, has an outer jacket wall that includes an external thread for connecting to a compensation structure, and a compensation structure having a flange-like setting element. An inner jacket wall of the setting element includes a threading configured to correspond to the external thread, and a socket-like anti-rotation element is disposed in a through-opening of the setting element, and an outer jacket wall of the anti-rotation element is connected to an inner jacket wall of the tubular connecting portion in a non-rotatable manner. The compensation structure is configured for presetting a distance in axial direction between the base device and a contact wall of the compensation structure extending orthogonally to the axial direction.

One-piece molded thermoplastic L-shaped and Z-shaped support brackets are described for supporting wiring and/or tubing. The support brackets will include a lower support flange, a backing flange, and a junction region having a concave inner surface and a convex outer surface which integrally joins the lower support flange and the backing flange to one another at a substantially right angle. The support brackets may be provided with a unitarily molded nut plate boss and a metal threaded nut cylinder which is embedded within and overmolded with the nut plate boss. Alternatively, a wire, cable or tubing mount unitarily formed as a one-piece molded unit with one of the support flanges so as to dependently extend therefrom.

A joint for a modular pole comprises a lower flange, an upper flange, and a transition section. The lower flange may have a lower flange external dimension which is greater than an upper flange external dimension. A fastener which may be useful in connecting the joint to a pipe or a stud comprises a through hole having an inner thread which does not span the entire distance of the through hole, and an outer thread on an exterior surface of the fastener with the inner thread and the outer thread having opposing thread directions. A modular pole comprises P.sub.n+1 pipes, T.sub.n joints, and a plurality of fasteners where n is an integer greater than or equal to 1.

An apparatus and method for holding a lug nut. The apparatus includes a base (150), a barrel (140), a lug nut engagement assembly (130), a plunger and a cam guide (170). The barrel (140) is coupled with the base (152) in a manner allowing the barrel (140) to move upwardly or downwardly within the base (150). The barrel (140) has an internal cam track portion (145). The lug nut engagement assembly (130) includes retractable fingers (132). The lug nut engagement assembly (130) is removeably affixed to the barrel (140). The plunger (160) is disposed within a portion of the lug nut engagement assembly (130), the barrel (140) and the cam guide (170). The plunger (160) has a tip for engagement with the retractable fingers (132). The cam guide (170) is disposed and moveable within a bottom portion of the barrel (140). The cam guide (170) has longitudinal rails (172) for engagement with the internal cam track (145) of the barrel (140).

A nut fastener assembly includes a nut assembly and a fastening clip. Opposite sides of the bottom of the nut assembly are provided with a pair of protrusions. The fastening clip includes a pair of lugs arranged on opposite ends of the fastening clip and extending towards the nut assembly, and a pair of receiving channels configured to respectively penetrate the pair of lugs. At least one of the pair of lugs is an adjustable lug including a blocking part and an elastic part. The distal end of the elastic part is movable relative to the distal end of the blocking part. The corresponding protrusion in the pair of protrusions can enter the corresponding receiving channel through a space between the distal end of the blocking part and the distal end of the elastic part to be held in the receiving channel.

Embodiments of showerhead assemblies and fasteners for use in coupling components of showerhead assemblies are provided herein. More particularly, the fasteners described herein can advantageously be used to connect a gas distribution plate to a backing plate of the showerhead assembly. The fasteners described herein can further advantageously be used to robustly connect components together where the components have different coefficients of thermal expansion.
